[Reoperations for early recurrent occlusions following femoropopliteal and femorocrural bypasses].

We analyse the early results of 333 patients who had been operated on because of femoropopliteal occlusions between 1996 and 2000. Most interventions (90.4%) were below knee reconstructions. The rate of crural bypasses was high (40.5%). We examined whether the length and type of the graft influenced the outcome of the primary operation. If below knee bypass was necessary in every operation autologous grafts were preferred either partially or entirely (saphenous vein or arm vein). The number of reocclusions and amputations was significantly higher if the distal anastomosis involved the crural arteries (p < 0.02), or the graft was not autologous (p < 0.01). There was no statistical difference between early results of saphena and arm vein bypasses (p = 0.2). Thirty-six reoperations were performed for early graft failures. Either the patient's general condition or local findings did not allow reoperations in 17 patients with occluded graft, they were treated conservatively. Nine patients died after surgery (2.7%). In the postoperative period 21 major amputations were necessary (6.3%), in six cases the graft was patient. After reoperations 7 patients needed amputations (19.4%), in the 17 patients not reoperated on the second time, 8 amputations were necessary (47%), the difference is significant (p < 0.05). We are convinced about the importance of urgent reoperation in case of early graft occlusion. If the run-off to the distal arteries was doubtful intraoperative angiography was performed. When distal extension of the operation was necessary we tried to use autologous grafts. The amputation rate was significantly lower after reoperations if the cause of graft occlusion was found and corrected compared to simple thrombectomies (p < 0.05).

Reoperations on cardiac valves.

As the number of patients undergoing cardiac valve replacement has grown, valve reoperations have become increasingly frequent. The newer generations of mechanical valves are far more efficient and freer from structural failure than the older ones. However, other valve and non-valve related complications still constitute a major cause of morbidity and mortality. On the other hand, bioprostheses, implanted in large numbers in the 1970's and early 1980's, have now gone into the second decade of life since implantation, when biodegradation becomes more frequent. Reoperations are technically more demanding than the original valve procedures because of the mediastinal and pericardial adhesions and the condition of the anulus after removal of the previous prosthesis. Greater awareness of the most dangerous steps and refinements to surgical technique have contributed to the decreased mortality observed in recent years. The risk is higher in certain conditions, such as the presence of prosthetic valve endocarditis and the patient being operated on an emergency basis in NYHA functional class IV. It may also be increased in females and the elderly. Multiple reoperations also carry a higher risk in most surgeon's experience. However, elective reoperations for defective mechanical valves and for replacement of a previously repaired mitral valve carry similar mortality rates to primary valve replacement procedures. The global mortality rates have not been significantly higher in the hands of experienced surgeons working in centers where reoperations are performed frequently. In smaller series high mortality rates are a constant, which underscores the importance of the learning curve. The indications for reoperation must therefore consider all risk factors and, when possible, the procedure must be performed by those who have the most experience. Under these circumstances, elective re-replacement of degenerating bioprostheses and of defective mechanical valves in asymptomatic patients may be advisable.

Minimal adhesions to ePTFE mesh after laparoscopic ventral incisional hernia repair: reoperative findings in 65 cases.

OBJECTIVES: Laparoscopic ventral incisional hernia repair involves intraabdominal placement of a synthetic mesh, and the possibility of formation of severe visceral adhesions to the prosthesis is a principal concern. Little clinical information based on reoperative findings is available about adhesions to biomaterials placed intraabdominally. We conducted a multiinstitutional study of adhesions to implanted expanded polytetrafluoroethylene (ePTFE) mesh at reoperation in patients who had previously undergone laparoscopic incisional hernia repair done with the same mesh implantation technique. METHODS: Nine surgeons retrospectively assessed the severity of adhesions to ePTFE mesh at reoperation in 65 patients. For each case, adhesions were assigned a score of 0 to 3, with 0 indicating no adhesions and 3 severe adhesions. RESULTS: The mean time from mesh implantation to reoperation was 420 days (range, 2 to 1739 days). No adhesions were observed in 15 cases. Forty-four cases received an adhesion score of 1, and 6 cases a score of 2; no scores of 3 were assigned. Thus, 59 patients (91%) had either no or filmy, avascular adhesions. No enterotomies occurred during adhesiolysis. CONCLUSIONS: In this large series of reoperations after laparoscopic incisional hernia repair, no or minimal formation of adhesions to implanted ePTFE mesh was observed in 91% of cases, and no severe cohesive adhesions were found. Comparative analyses of newer materials based on clinical reoperative findings are warranted to assess the safety of intraabdominally placed meshes.

Indications for reoperation for valvular prosthesis dysfunction in urgent and elective patients.

OBJECTIVES: Comparison analysis of indications for operation, early clinical outcomes and hospital mortality between patients reoperated for valvular prosthesis dysfunction urgently and electively. MATERIAL AND METHODS: Retrospective data analysis of 94 patients (pts) reoperated for valve prosthesis dysfunction at Department of Cardiovascular Surgery and Transplantology in Kraków, Poland between January 1999 and December 2002. RESULTS: Valvular reoperation was elective procedure in 69 pts (73.4%)--group A: 46 males (M), 23 females (F), age 23-71 (av. 51.31 +/- 10.2). Urgent operation was performed in 25 pts--group B: 17 M, 8 F, age 29-77 years (av. 5.41 +/- 13.26). In group B: 9 patients underwent reoperation for dysfunction of aortic valve (2 allogenic, 7 mechanical), 13 pts for mitral valve dysfunction and 3 pts for both aortic and mitral valve dysfunction. In group A: 24 pts for mitral valve dysfunction, 37 pts for aortic valve dysfunction (25 allogenic, 12 mechanical) and 8 pts for both aortic and mitral valve dysfunction. In group B: 16 pts (64%) were operated in NYHA class IV; 8 in cardiogenic shock; on which 8 pts with active endocarditis, 3 pts with sepsis and 1 patient in septic shock. Average operative risk calculated as Euroscore was 30.86 in group B and 13.15 in group A (p<0.05). Overall hospital mortality was 12.6% (12 pts). In group B: 7 pts died (28%), 3 pts due to multiorgan failure, 1 patient due to sepsis, 2 pts due to aorta rupture and 1 due to left ventricle rupture during cardiopulmonary rescuscitation. In group B 5 pts died (7.2%). CONCLUSION: Patients reoperated urgently for valve prosthesis dysfunction were in worse preoperative state, had significantly higher preoperative risk and in hospital mortality than patients reoperated electively.

[Quality of life after homograft aortic valve replacement and reoperation].

AIM: To evaluate quality of life (QoL) in patients after aortic homograft implantation for aortic valve disease and in those who had undergone reoperation due to homograft dysfunction. METHODS: QoL was assessed in 354 patients (72 women and 282 men, mean age 55.1 +/- 11.5 years, range 13-69) after aortic homograft implantation. Patients were divided into two groups: I--patients after aortic homograft implantation without reoperation (291 patients) and II--patients after reoperation (68 patients). We used two questionnaires: SF 36 (Short Formulation 36) and a self-developed questionnaire for patients after cardiac operation (SDQ). SF 36 has three levels: a) 36 items; b) eight scales: physical activity, social activity, limitations in every day activity, body pain, mental health, emotional problems, vitality and health perception; c) two summary measures that aggregate scales; general physical health which constitutes of physical activity, limitations in every day activities, body pain, health perception and general mental health which constitutes the rest of four scales: social activity, mental health, emotional problems, vitality. Each scale is standardized from 1 to 100 with > 50 indicating better than general population average. SDQ is focused on social and demographic factors, clinical symptoms before and after operation, risk factors and physical and occupational activity. RESULTS: By SF 36, only health perception was below general population average. We found a statistically positive relationship between QoL and high physical and occupational activity in both groups (p<0.05). The presence of dyspnea, chest pain, palpitations, edema, faints, fear/anxiety and hypertension were related to decreased general physical and mental health in both groups (p<0.05). CONCLUSIONS: Patients after aortic homograft implantation have high QoL. This holds also for those after reoperation for homograft dysfunction. Symptomatic patients have lower QoL. Higher QoL is associated with physical and occupational activity. There is no difference in general physical health in both groups. General mental health is decreased in reoperated patients. Since reoperated patients more often suffer from emotional problems, they may particularly benefit from the psychological support.

[Reoperation after limb salvage surgery with prosthesis for bone tumor].

OBJECTIVE: To analyze the causes and the reoperation therapies after salvage limb surgery with prosthesis for bone tumors. METHODS: The retrospective analysis was performed on 85 patients undergoing the limb salvage operation with prosthetic replacement for tumors from January 1994 to December 2004. Of the patients, 21 (13 males and 8 females, aged 18-58 years) underwent reoperations for various reasons. All the diagnoses were pathologically confirmed (10 patients with osteosarcoma, 4 with chondrosarcoma, 5 with giant cell tumor of the bone, 2 with osteofibrosarcoma). The distal femur was involved in 9 patients, proximal tibia in 8, proximal femur in 2, proximal humerus in 1, and acetabulum in 1. According to the Enneking surgical grading system, there were 5 patients in I B and 16 in II B. The time between the first operation and the reoperation was 2 weeks to 20 years. The common reasons for the reoperation were tumor recurrence in 8 patients, prosthetic loosening in 5, no healing of the incision in 4, joint dislocation in 3, and implant fracture in 1. The amputation and the prosthesis revision were respectively performed on 6 patients, extensive resection of the tumor on 3, the myo-skin flap translocation on 4, internal hemipelvectomy without reconstruction on 1, and open reduction on 1. RESULTS: The follow-up in 18 patients for 1-5 years (average, 3 years and 4 months) revealed that 4 patients died of osteosarcoma with pulmonary metastasis. The other 14 patients had no tumor recurrence or loosening of the prosthesis, and the incisions healed well. The assessment on the joint function was performed on 13 of the 18 patients and the results were as follows: excellent in 2 patients, good in 5, fair in 4, and poor in 2, with a satisfaction rate of the reoperation with limb salvage of 84.6% and an excellent-good rate of 53.8%. CONCLUSION: Tumor recurrence is the most common reason for the reoperation after the limb salvage with prosthesis for tumors, and loosening of the prosthesis is an important reason, too. By the rules of the bone tumor limb savage, the limb salvage operations can also be performed, which can achieve a satisfactory result of the limb function.

Results of reoperations for coronary artery disease.

Seventy-one patients undergoing reoperation for coronary artery disease were examined on average 2.5 years postoperatively. Operative mortality was 9.9% and late mortality 6.3%. 88% of the patients improved subjectively, and although only 7.8% were angina-free, 79.9% were in NYHA Class I or II. All patients who had been working before reoperation returned to work, and either patients who were on sick-leave before resumed their activities. A follow-up examination was performed in 21 patients with a follow-up time of more than three years. The mean peak work capacity did not change after reoperation and also the ST changes during the bicycle ergometer exercise test were the same after reoperation. The mean ejection fraction diminished from 54 +/- 15.5% to 44.7 +/- 15.2%. In thallium perfusion studies areas of hypoperfusion were observed in 14 cases (67%). Coronary angiograms showed 3.0 +/- 1.0 patent anastomoses at the follow-up examination; 76% of the anastomoses performed in the reoperations were patent. It can be concluded that although the objective results of repeat myocardial revascularisation in this material are not optimal, the subjective improvement of the patients was satisfactory, and in the majority of cases reoperation ensures an acceptable quality of life for years.

[Reoperation for aortocoronary bypass].

Iterative aorto-coronary bypass. From 1978 to 1988, 106 previously revascularized coronary patients were reoperated. This represents 3.01% of all aorta-coronary bypass procedures performed in the same period. Characteristics of this group, risk factors, coronary anatomical data, perioperative morbidity and mortality are analyzed and compared to the data of primary revascularization. The progression of atherosclerotic disease, with an annual 2% attrition rate of bypass grafts after the first year, is evidenced by this study. The success rate of coronary reoperations approaches the results of primary bypass surgery. The causes of recurrent angina and graft failure are discussed. The mean age of individuals requiring reoperation is 58.5 years. The mean interval between the two operations reaches 66 months (5 to 168 months). Angiographic lesions are more extensive, with a three vessel disease in 75% of the reoperated patients and an ejection fraction lowered at 55%. A mean of 2.7 bypass grafts per patient is realized, with in 60% of cases an internal mammary artery graft. Perioperative infarction occurs in 10.5% of the reoperations and in 4.5%, an intraaortic counterpulsation balloon is necessary at the end of the procedure. Symptomatic improvement is obtained in 85% of cases. Operative mortality is 5.7%. These findings suggest that coronary reoperation can be accomplished with low morbidity, low mortality and a therapeutic benefit in the majority of cases. In recent years, cardiac transplantation has been considered for some patients with impaired ventricular function. This procedure is only limited by the insufficient number of donors.

[Reoperation in patients with heart valve prostheses. Analysis of risk factors affecting perioperative mortality].

Sixty-two patients with at least one prosthetic heart valve each underwent a total of 70 reoperations. Their cases were analysed with special regard to the risk of perioperative mortality and to the factors affecting that risk. The age of the patients studied was 47 +/- 14.6 years (mean +/- 1 SD), and 4.75 +/- 4 years had elapsed since their previous operation. A total of 85 prostheses were implanted at the time of initial surgery. Forty-nine of those were mitral, 28 were aortic, and 8 were tricuspid prostheses. There were 48 mechanical valves, 24 bioprostheses and 13 Carpentier rings (9 of the latter being mitral and 4 tricuspid). At reoperation (n = 70) 95 valves required treatment. Eighteen patients died following their first reoperation (18/62, 29%), and two more died after a second reoperation (2/8, 25%). Actuarial probability of hospital survivors being alive 8-9 years following reoperation was 47 +/- 15%. It was found by multiple regression analysis that the duration of cardiopulmonary bypass (p less than 0.01), surgical priority (p less than 0.05) and the patient's age (p less than 0.05) were the only independent predictors of hospital death. A review of the literature and our own results suggest that surgical problems encountered with reoperation have unfavourably affected surgical results in the past. Objective risk factors are currently more related to the operative outcome. For these to be neutralised, patients with dysfunctioning prosthetic heart valves should be operated at an early stage before they reach a critical one. Only patients with stable, mild dysfunction unlikely to worsen acutely may probably be followed-up safely.

Reoperation for coronary artery disease. 10 years of clinical follow-up.

From a 15-year follow-up study of 743 patients who underwent initial operation for coronary artery disease, 64 patients required reoperation for recurrence of angina and were followed-up for 15 years or less (mean, 6.2 years). Patients undergoing reoperation tended to be older but not significantly so (50.9 +/- 8.3 years vs. 57.5 +/- 9.7 years), had more left main coronary artery disease (p less than 0.001), and had more triple-vessel disease (p less than 0.001) than those undergoing the initial operation. There were no significant differences in sex, prior myocardial infarctions, or prevalence of abnormal ventriculograms between the two groups. The cumulative survival rate during a 10-year follow-up period after reoperation did not differ from the rate after the initial operations. There was less relief of angina in the first year after reoperation than after initial operation, but thereafter, the annual increases in recurrence of angina were similar. Although there were more myocardial infarctions after reoperation in the first 6 postoperative years, the cumulative incidence after 10 years did not differ between the two groups. We conclude that reoperation yields a similar survival benefit but produces less early relief of angina than initial operation.

Reoperation within 2 years of aortofemoral bypass.

The authors analysed 267 consecutive primary aortofemoral grafts to identify the reasons for reoperation within the first 2 years postoperatively. Forty-one (8%) of the 521 limbs required a second operation. Precursors to reoperation were: occlusion of a superficial femoral artery (12%), gangrene (27%) and severe acute ischemia (35%). The rationale for reoperation was classified as technical 11, questionable selection (candidates for percutaneous transluminal angioplasty or inappropriate operation) 9, disease progress 11, residual symptoms 9, contralateral symptoms 1. The commonest technical problem was blind endarterectomy which preceded seven reoperations, five for thrombosis of the graft or a superficial femoral artery which was patent initially. Although 218 limbs had an occluded or severely stenosed superficial femoral artery, only 26 (12%) required reoperation within the first 2 years. The authors believe that the incidence of reoperation after aortofemoral bypass can be reduced by identifying the limbs at risk, by appropriate selection for percutaneous transluminal angioplasty, avoiding blind outflow endarterectomy and considering concomitant femoropopliteal bypass when gangrene is present.

Reoperation for polytetrafluoroethylene bypass failure: the importance of distal outflow site and operative technique in determining outcome.

Of 724 bypasses with polytetrafluoroethylene grafts performed for critical ischemia during a 6-year period, 165 (23%) failed and necessitated reoperation for continued limb salvage. Forty-three failures occurred in 199 femoral-above-knee-popliteal bypasses (F-AKP), 33 failures in 177 femoral-below-knee-popliteal bypasses (F-BKP), 52 failures in 182 femorodistal bypasses (F-D), 28 failures in 85 axillofemoral bypasses (Ax-F), and nine failures in 81 femorofemoral bypasses (F-F). Our reoperative approach consisted of dissection of the distal anastomosis, longitudinal incision in the hood of the graft directly over the anastomosis, and proximal graft thrombectomy. Intimal hyperplasia was treated by patch angioplasty, proximal or distal progression of atherosclerosis was treated by a graft extension, and thrombectomy alone was performed when no cause of graft failure was identified. More recently, a totally new bypass was constructed in 27 cases of F-BKP or F-D failures. Reoperations featuring graft salvage for failed extra-anatomic and F-AKP bypasses yielded 3-year patency rates from the time of first reoperation of 71% and 52%, respectively, whereas for F-BKP and F-D reoperations, 3-year patency rates were 13% and 15%, respectively, at 3 years. However, totally new grafts to a different outflow artery in these settings had 3-year patency rates of 48% and 39%. These data support the aggressive use of reoperation with graft salvage when F-AKP or extra-anatomic graft failure reproduces critical ischemia. Conversely, a new bypass to a virginal outflow site, preferably with autologous vein, should be performed when a polytetrafluoroethylene F-BKP or F-D bypass fails.

[Reoperation on valve bioprostheses. Apropos of 64 cases].

Sixty-four patients with one or more bioprostheses were reoperated between 1970 and 1982. Reoperation was performed for degenerative lesions in cases (48%), for aseptic periprosthetic leaks in 18 cases (28%), for infectious lesions in 13 cases (21%) and for thrombosis in 2 cases (3%). Degenerative and infectious lesions were commoner in aortic bioprostheses whilst periprosthetic leaks were commoner in mitral bioprostheses. The average interval between operations was 38 months. This was shorter in patients reoperated for mechanical problems (6 months) than those with infections (28 months) or degenerative (5 years) complications. At reoperation 14 prostheses were reinserted and 50 were replaced. The global hospital mortality was 21% (14 deaths). The mortality was related to the surgical indication: mechanical lesions (11%), degenerative lesions (16%), infectious endocarditis (38%), thrombosis (100%). The mortality rate also varied with time (36% during the period 1970-1978 and 18% during the period 1979-1982). This improvement was related to two factors: the use of cardioplegic solutions for myocardial protection and earlier recognition of surgical indications before the onset of irreversible haemodynamic complications. When choosing a valvular prosthesis, the mortality of reoperation for degenerative changes is the only disadvantage of the bioprosthesis which is silent, rarely complicated by thromboembolism and which does not require anticoagulant therapy for life. The mortality has decreased with time and will continue to fall if the indications for reoperation are based on stethacoustic, electrical, radiological and echocardiographic criteria of valvular dysfunction and not on the presence of overt cardiac failure as is still often the case.

Reoperation for complications of renal artery reconstructive surgery undertaken for treatment of renovascular hypertension.

Seventy-two secondary operations for complications of prior renal artery reconstructive surgery were undertaken in 58 patients. This experience evolved from the management of 373 patients who underwent 425 primary operations for renovascular hypertension. Secondary operations were performed 10 times in pediatric patients following 42 primary procedures (24%); 44 times in adult fibrodysplastic patients following 199 initial operations (22%); and 18 times in atherosclerotic patients after 184 primary operations (10%). The overall reoperation rate was 15.5% (58 of 373 patients). Reoperation typically followed persistent or recurrent hypertension caused by graft thromboses, perianastomotic graft narrowing, or progressive nonanastomotic graft stenoses. Aneurysmal deterioration of vein grafts was an uncommon reason for reoperation. Secondary reconstructions included nephrectomy (31), bypass with vein grafts (15) or prosthetic grafts (8), angioplasty or reimplantation (12), thrombectomy (4), and operative dilation (2). Benefits regarding hypertension control were afforded 91% of these patients. One death occurred among the 72 reoperations, representing a 1.4% operative mortality rate. Reoperative renal artery reconstructive surgery for complications of renal revascularization may present formidable technical problems. Early diagnosis and prompt reoperation with exacting vascular surgical techniques are most likely to provide optimal results.

[Reoperation for primary hyperparathyroidism].

Twenty-one patients in a series of 283 treated surgically for primary hyperparathyroidism between 1960 and 1982, underwent reoperation. Eleven had been previously treated elsewhere. The initial cervicotomy was negative in fourteen cases, but had led to the ablation of one or more adenomas in seven. The reason for reoperation was recurrence or persistence of hyperparathyroidism (HPT). It was commenced by cervicotomy in the eleven patients initially treated elsewhere, and by cervicotomy and/or sternotomy for the others. Reoperation involved ablation of adenomas in thirteen cases, but was negative in the remaining eight. Three of the eight underwent a second reoperation, with success in two cases. Overall, reoperations led to ablation of sixteen adenomas in fifteen patients. Ten adenomas were ectopic, including eight located mediastinally . Ten sternotomies were performed, leading to ablation of four mediastinal adenomas. Postoperative complications included five recurrent paralyses and two severe cases of hypocalcemia. One patient with parathyroidal carcinoma died of malignant hypercalcemia. Fifteen of the twenty one patients (71%) were cured of their HPT. Basing themselves on these cases, and a review of the literature, the authors describe the indications and practical management of reoperative surgery for primary HPT.

Reoperation after correction of tetralogy of Fallot.

Forty-one patients underwent reoperation after total correction of tetralogy of Fallot from 1962 through 1979. The indications for surgical repair were recurrent or residual lesions alone or in combination with other lesions. The reoperation consisted of closure of a residual ventricular septal defect (VSD) in 28 patients, relief of residual right ventricular outflow tract (RVOT) gradient in 11, tricuspid value replacement, repair or annuloplasty in six, aneurysmorrhaphy or excision of an RVOT aneurysm in five, insertion of a right ventricular-pulmonary artery valved conduit in five, insertion of an RVOT valve in three, closure of a patent foramen ovale or atrial septal defect in three, repair of a residual surgical shunt in three, mitral valve replacement in one patient, and aortic valve repair in one. Thirty-eight patients (93%) survived the operation. The surgical mortality decreased from 25% during 1962 through 1970 to 0% during 1971 through 1979 (p = 0.02). There was one late death. Five patients (12%) required a second-reoperation for recurrent VSD. Even a small residual shunt, especially when associated with other defects such as pulmonary insufficiency or tricuspid insufficiency, may cause clinical deterioration that can be improved by reoperation. This study tends to support the policy of recommending reoperation when either RVOT obstruction (gradient greater than or equal to 50 mm Hg) or isolated VSD (Qp/Qs greater than 1.5) is present. Reoperation is associated with a low mortality and good long-term results.

Reoperation in patients with a bioprosthesis in the mitral position: indications and early results.

Our experience with 221 patients undergoing a first reoperation for bioprosthesis failure in the mitral position is reviewed. Most, (196, 89%) were reoperated because of structural valve deterioration, 16 (7%) had periprosthetic leak and nine (4%) had prosthetic endocarditis. Operative mortality (23 patients overall, 10.4%) was significantly higher in those patients who were in NYHA functional class IV or had impaired left ventricular function, in those reoperated because of prosthetic endocarditis and those undergoing emergency reoperation. Those patients who had structural valve deterioration, good left ventricular function and who were reoperated electively had the lowest operative risk. With increasing experience and the use of standardized surgical techniques, the results of reoperation for bioprosthetic failure have improved considerably in recent years. A further reduction in operative risk can be expected with better patient selection, obtained through more careful non-invasive assessment of valve performance to detect the initial signs of bioprosthetic failure.

[Reoperative coronary revascularization without cardiopulmonary bypass].

We report a case of successful reoperation of coronary revascularization without cardiopulmonary bypass. The patient was a 62-year-old man, who had undergone coronary artery bypass grafting (CABG) to the LAD and CX with two saphenous vein grafts (SVG) for the left main lesion 12 years before. He required reoperation for unstable angina due to progressive ischemic heart disease and the diseased SVG. Preoperative coronary angiogram revealed total occlusion of major 3 branches and the diseased SVG to the LAD. The reoperation was performed without cardiopulmonary bypass through the repeated median sternotomy for revascularization of the LAD and RCA. The left internal thoracic artery and the gastroepiploic artery were anastomosed to the LAD and RCA under the beating heart without any hemodynamic or electrocardiographic deteriorations. The operation was uneventfully finished in 3 hr 40 min. without the use of blood products. Postoperative angiogram showed both new grafts were widely patent, and he was discharged 14 days after the operation without angina. We also performed 4 other cases of reoperative CABG without cardiopulmonary bypass, and conclude that this technique is a safe and effective alternative in a carefully selected group of patients for reoperative CABG to reduce several technical problems related to coronary reoperation.
