[False aneurysm on dacron prosthesis, 20 years after aortofemoral bypass].

A 85-year-old male developed a false, non septic, non anastomotic aneurysm, 20 years after right aorto-femoral Dacron grafting for claudication. On account of the proximity to the femoral anastomosis, and the association with a profunda femoris stenosis, a conventional surgical repair was preferred to an endovascular treatment. The patient underwent a successful aneurysm resection followed by PTFE interposition between the primary graft and the profunda femoris artery, with uneventful recovery.

[Inguinal hernia repair in a teaching course for surgeons. A training program].

The Authors suggest a training programme for surgeons in post graduates courses. With this object in view, the inguinal hernia repair by Lichtenstein has been chosen as the most suitable one. The training course has been divided into theoretic lessons and surgical practice in the operating theatre, carried out in stages as assistant and then as operating surgeon. The good standard achieved, together with the clinical results obtained, demonstrates the effectiveness of the teaching method.

Distal polytetrafluoroethylene bypasses in patients older than 75 years.

HYPOTHESIS: Polytetrafluoroethylene (PTFE) alone is justified for infrapopliteal arterial grafting in elderly patients with critical ischemia of the lower limbs who lack a suitable, autogenous saphenous vein. DESIGN: A consecutive sample clinical study with a mean follow-up of 16 months. SETTING: The surgical department of an academic tertiary care center and an affiliated secondary care center. PATIENTS: Thirty-one patients older than 75 years with critical ischemia of the lower limbs received 34 PTFE bypass grafts to the infrapopliteal arteries: 12 patients to the anterior tibial, 8 to the peroneal, 8 to the posterior tibial, and 2 to the dorsalis pedis artery. MAIN OUTCOME MEASURES: Cumulative survival, primary graft patency, and limb salvage rates expressed by standard life-table analysis. RESULTS: Operative mortality rate was 3%. Cumulative survival rate was 80% at 2 years (SE, 9.2%) and 43% at 3 years (SE, 11.4%). Cumulative primary patency rate was 67% at 2 years (SE 9.1%), and 61% at 3 years (SE, 12.7%). Cumulative limb salvage rate was 77% at 2 years (SE, 8.7%) and 70% at 3 years (SE, 12.8%). CONCLUSION: Polytetrafluoroethylene alone is justified as graft material for infrapopliteal bypass grafts in elderly patients with critical ischemia of the lower limbs and without a suitable autogenous saphenous vein.

Transsternal approach to closure of bronchopleural fistulas after pneumonectomy. A fifteen cases report.

A treatment method for main bronchus fistula after pneumonectomy via median sternotomy was described by P. Abruzzini in 1961. This operation is performed in an area not involved with infection. Fifteen patients underwent the procedure in our surgical department; one of them died of myocardial infarction while all the others survived for different periods of time, closely associated with the original disease; seven were long-term survivors. The transmediastinal approach seems an effective means of managing such a difficult complication.

Seat-belt-related injuries to the supra-aortic arteries.

Five seat-belt-related injuries occurring in four adults are reported. One injury involved the common carotid artery, two the internal carotid and two the subclavian arteries. Three of the four injured persons were asymptomatic and one had delayed-onset symptoms; none suffered stroke. There was no operative mortality or morbidity. Overall, the functional results of arterial reconstruction were good, with satisfactory patency at follow-up averaging 15 months.

Results of distal revascularization in elderly patients for critical ischemia of the lower limbs.

Thirty eight patients over 75 years of age were operated upon of 40 distal arterial revascularizations for critical ischaemia of the lower limbs. Arterial reconstruction was proposed to ambulatory, self sufficient patients, with a patent artery of the leg or the foot in continuity with pedal arch, at arteriography. The revascularized artery was the peroneal in 14 cases, the anterior tibial in 11, the posterior tibial in 9, the dorsalis pedis in 5, and the external plantar artery in 1 case. Postoperative mortality was 2.6%. No postoperative arterial occlusion occurred and no postoperative amputation needed to be performed. The mean follow-up of 37 patients surviving operation was 21 months (ext. 2-52 months). At 36 months interval, patients' survival was 43%, primary patency rate was 57%, and limb salvage rate was 76%, at life-table analysis. Distal revascularization enables a good number of elderly patients in critical ischaemia of the lower limb, to enjoy an active, independent life, with a viable limb.

Results of bypasses to the anterior tibial artery through the interosseous membrane.

The purpose of the present study was to retrospectively evaluate the results of anatomically tunneled grafts to the anterior tibial artery for distal revascularization in terms of patency and limb salvage rates as well as local morbidity, which can lengthen the postoperative hospital stay. Twenty-three patients received 24 bypasses to the anterior tibial artery, with grafts tunneled through the interosseous membrane. The mean age was 67 years; 10 patients were diabetic, 12 were smokers, 9 presented with significant coronary artery disease, and 2 with chronic renal insufficiency. The donor vessel was the common femoral artery in 17 cases, the superficial femoral artery in 4, and the infra-articular popliteal artery in 3. The graft material consisted in the reversed saphenous vein in 4 cases, the non-reversed devalvulated ex situ saphenous vein in 11, composite polytetrafluoroethylene (PTFE) + inversed saphenous vein in 6, and PTFE alone in 3 cases. No postoperative mortality was observed, nor was there postoperative graft occlusion or need for major amputation. The average postoperative length of stay in the hospital was 9.7 days. Two local surgical wound complications were observed, which did not necessitate a postoperative hospital stay exceeding 15 days. Cumulative primary patency and limb salvage rates at 3 years were 50% and 70%, respectively. Anatomic tunneling of grafts to the anterior tibial artery yields patency and limb salvage rates comparable to those reported in the literature for distal bypasses and, considered overall, an acceptably low local morbidity and short hospital stay. Definitive superiority over externally tunneled grafts, however, is not definitely demonstrated by this study and should be prospectively tested.

Endocaval suture of aortocaval fistula.

A case of aortocaval fistula complicating a ruptured infrarenal aortic aneurysm is reported. As the length of the defect and the thickness of the aortic wall made repair from within the aorta unsafe, the defect was repaired from within the vena cava. The details of the technique are reported. It can be a useful alternative to inferior vena cava ligation, when standard repair of aortocaval fistulae from within the aorta is risky or difficult to attempt.

[Bifurcated prosthesis in infrarenal aortic position in stenosing lesions. Functional results].

Fifty-eight patients operated upon of infrarenal aortic bifurcated grafts for occlusive disease, in a 6-year period, have been followed-up with a minimum interval of 2 years. The patients were in claudication stage in 63% of the cases and in critical limb threat ischemia in 37% Bypass consisted always in a bifurcated knitted dacron graft either pre-coagulated or sealed. Infrarenal aorta has always been the donor axis, whereas distal anastomosis has been performed on both common femoral in 80% of the cases, on at least one external iliac in 20%. In 5% of the cases a femoro-popliteal bypass has been associated to the main procedure. Postoperative mortality was 3.5%. The occlusion of a prosthetic branch in the postoperative period occurred in one case, requiring a major amputation. Seven patients (12%) presented 11 late thrombosis of one prosthetic branch or both on an interval varying from 4 to 62 months. Eight occlusions required reintervention. Only one, lethal, late prosthetic sepsis was recorded. In a mean interval of 54 months, a good or fair functional result was achieved in 93% of the patients. Out of 22 patients specifically questioned upon, 82% returned to their normal work activity, whereas 18% retired but had a fully normal everyday's life. Sexual function was ameliorated or unchanged in 67% of the cases, while it was impaired in 33%. Eighty-seven percent of the followed-up patients did not require any further hospitalisation for atherosclerotic disease, while 13% of them experienced subsequent hospitalisation or reintervention for progression of the disease either at the same or at different arterial sites. Overall good results support an aggressive attitude towards aorto-iliac-femoral grafting for occlusive disease.

[Simultaneous carotid and vertebral revascularization in the aged].

Five patients of a mean age of 76, have been submitted to combined vertebral and carotid artery revascularization for a severe vertebro-basilar insufficiency. Vertebral artery revascularization consisted of a transposition to the common carotid artery in one case and of a carotid-distal vertebral artery saphenous bypass graft. The associated carotid artery revascularization consisted of a carotid endarterectomy with patch in 4 cases and without patch in one case. There were no postoperative mortality and no postoperative stroke. Postoperative morbidity included a transitory revascularization syndrome, a myocardial ischemia and a Horner's syndrome. Complete relief of vertebrobasilar symptoms was obtained in 4 patients whereas in one patient only a mild positional vertigo persisted. All vascular reconstructions have been assessed with postoperative arteriography and duplex-scan every six months. At 11 months mean follow-up, all revascularizations are patent. Combined carotid and vertebral artery surgery is effective in well selected cases, and it does not enhance the risk of the two operations performed separately. It also eliminate the possibility of failure of isolated carotid revascularization for vertebrobasilar symptoms.

Results of axillofemoral by-passes for aorto-iliac occlusive disease.

The purpose of this study was to review our results with axillofemoral by-passes performed for aorto-iliac occlusive disease. Fifty patients receiving 51 axillofemoral by-passes from January 1989 to December 1994 were retrospectively reviewed. The 30-day post-operative mortality was 4%. Seven patients (14%) presented graft-related local complications and all but one required reoperation. Five patients were lost to follow-up, the mean length of which was 36 months (16-74 months). Forty-nine per cent of the patients died during the follow-up period. At 36 months, the primary patency rate was 51%, the secondary patency rate was 69%, and limb valvage rate was 87%. A statistical difference was seen in the secondary patency rate between axillobifemoral by-pass (87%) and axillo-unifemoral by-pass (56%) at 36 months (P < 0.01), but no difference was seen in the limb salvage rate at 36 months between the two configurations of the by-pass (94% vs 81%) (P = NS). Twenty patients (40%) operated upon for acute ischemia had a significantly higher post-operative mortality rate (10% vs 0), a significantly higher amputation rate (20% vs 6.6%) and a significantly lower patency rate of by-pass (26% vs 63%) (P < 0.01), than the 30 patients (60%) operated on for claudication, rest pain or trophic ulcers. Our findings indicate that the results of axillofemoral by-pass are significantly influenced by the selection of patients for operation, namely the clinical status of ischaemic symptoms, and that since the overall results of axillofemoral by-pass are inferior to those of aortofemoral by-pass, this treatment should be restricted to patients at high risk of aortic clamping.

Infectious aneurysm of the interosseous artery at the forearm. Case report.

The case of an infectious aneurysm of the interosseous artery at the right forearm is reported, with presenting symptoms consisting in pain, loss of motor functions and paresthesias. The association of occupational trauma and hematogenous bacterial grafting were the possible etiologic agents. Diagnostic evaluation included ultrasound, Doppler study, CT-scan and arteriography, but the exact origin of the mass from the interosseous artery could be detected only at operation. As good collaterals were present at preoperative evaluation, simple excision followed by debridment and ligation was performed with a good result. The isolated infecting agent belonged to the salmonella species.

Local anaesthesia with eutectic cream of lidocaine and prilocaine for treatment of cicatrizial phimosis in outpatients.

The authors report their experience in ambulatory treatment of cicatrizial phimosis in outpatients, by using local anaesthesia with eutectic cream of lidocaine and prilocaine. This preliminary study shows that preparation seems to be effective and well tolerated. To the aim of getting a good analgesic result the most important aspects are a careful application of the cream all over the concerned area and an occlusive bandage for 60-90 minutes at least.

Neurinomas of the brachial plexus: case report.

Neurinomas, also referred to as neurilemmomas and schwannomas, are rare benign tumours of the peripheral nerves, a low proportion of which arise from the brachial plexus. Authors report a case of an ancient schwannoma arising from the brachial plexus. The tumour, usually asymptomatic, may cause sensory radicular symptoms, or rarely motor deficits in the involved arm. Enucleation of the tumour from the nerve without damage to any of the fascicles is the correct treatment.

Surgical treatment of T3 lung cancer invading the chest wall.

Lung tumors invading the chest wall are classed as belonging to the T3 group and are considered potentially resectable. Their management, however, is controversial, and extrapleural resection, when possible, is preferred to en bloc resection which is regarded as a far more invasive and dangerous operation. Five year survival rates for completely resected cases range in the literature from 25 to 35%, but survival rates are much worse if lymph node metastases are present. These poor outcomes have prompted the development of combined surgical approaches: preoperative radiation therapy, with or without chemotherapy, has been used with an improvement in resectability rates, but only modest results in terms of median survival; in a number of case series, increased operative morbidity and mortality have been reported with this approach. The present report relates to 122 patients treated by en bloc (20 cases) or extrapleural (102 cases) resection, 31 of whom also received neoadjuvant treatment. The operative mortality was 4.6%. Median survival was 17 months after en bloc resection and 19 months after extrapleural resection. Though no statistically significant difference was found, extrapleural resection would appear to yield better results than the en bloc procedure.

Second primary lung cancer: possible prediction, treatment and prognosis.

The incidence of second primary lung cancer (SPLC) seems to have increased in recent years. In our series that included more than 4000 patients with lung cancer and 1600 operations, we observed 26 cases of SPLC up until June 1999. We considered the standard criteria accepted by most authors for the selection. Characteristics of patients and tumors at the time of the first operation were compared with the statistical data of our general series. Age, sex, performance status and smoking were all considered, as well as cancer site, histology, stage and type of first surgical operation. No significant independent factor could be identified for the prediction of a new tumor at that time. A second operation was possible in 16 cases: two patients died in the postoperative period, two survived for 12 and 24 months, respectively, 12 are still alive 8-87 months after the new resection. The high rate of surgical cases (16/26 = 62%) and a good survival rate is clearly correlated with an early diagnosis of SPLC.
