Primary cardiac osteosarcoma in a pregnant woman.

Primary cardiac osteosarcomas are uncommon tumors. Their growth pattern is aggressive and the prognosis is poor. A 34-year-old, 7-month pregnant woman with a primary cardiac osteosarcoma associated with the anterior mitral leaflet and connected to the interatrial septum, causing nearly subtotal obstruction of the mitral valve, presented with a clinical picture of heart failure. Transthoracic echocardiography demonstrated an abnormal mass located in the mitral anterior leaflet, prolapsing into the left ventricle. Radical resection of the mass and replacement of the mitral valve were performed under cardiopulmonary bypass. Histopathology showed a low-grade osteosarcoma. The postoperative course was uneventful, and the patient was discharged on the 16th day after surgery. She gave birth after 2 months to a healthy baby after the successful operation. She and her baby did not have any problem during 3 months of follow-up.

Comparison of levels of inflammatory markers and hemostatic factors in the patients with and without peripheral arterial disease.

INTRODUCTION: Peripheral arterial disease is one aspect of atherosclerosis, a disease associated with both inflammation and hypercoagulability. Many recent studies have focused on the diversity of mechanisms by which inflammation can promote blood clotting. However, the relationship between plasma concentrations of inflammatory and hemostatic markers and the severity of atherosclerosis is not yet well studied. We want to determine the relations among selected D-dimer, C-reactive protein, fibrinogen, prothrombin time and serum amyloid A, and the ankle brachial index in patients with and without peripheral arterial disease. MATERIALS AND METHODS: In a prospective cohort study, 45 consecutive patients with peripheral arterial disease of ankle brachial index<0.90, and 44 patients without peripheral arterial disease of ankle brachial index 0.90 to 1.50 were included. D-dimer, fibrinogen, C-reactive protein, serum amyloid A, and prothrombin time were measured at the recruitment. RESULTS: Median values of serum amyloid A, D-dimer, and C-reactive protein were significantly higher in the peripheral arterial disease group than in those without peripheral arterial disease group (p<0.001). The patients with PAD had moderately higher fibrinogen levels than without PAD (p<0.01). Prothrombin time levels were normal in both groups. In multivariable regression analyses adjusting for all blood factors as well as potential confounders, patients with peripheral arterial disease, levels of serum amyloid A, and C-reactive protein showed a highly significant, inverse association with the ankle brachial index. D-dimer and fibrinogen level increase were also found to be related to lower ankle brachial index, while no association was observed between prothrombin time levels. CONCLUSIONS: Higher C-reactive protein, serum amyloid A, and D-dimer levels are showing positive association with the presence of peripheral arterial disease. C-reactive protein and serum amyloid A levels are direct relations between the ankle brachial index and the extent of vascular inflammation.

Primary arteriovenous fistulas in the forearm for hemodialysis: effect of miscellaneous factors in fistula patency.

BACKGROUND: The provision and maintenance of vascular access remains a major cost to end-stage renal failure programs. In addition, vascular access occlusion, results in significant morbidity in hemodialysis patients. Age, gender, diabetes mellitus, malignancy, smoking habits, administration of heparin per hemodialysis session, previous dialysis catheter insertion, number of hemodialysis sessions and location of the fistula may be associated with survival of the primary arteriovenous fistula. We examined the effects of various factors on fistulas in 412 chronic renal insufficiency patients. METHODS: From 1995 to 2004, 412 arteriovenous fistulas were created by the Department of Cardiovascular Surgery at the Medical Faculty of Atatürk University for hemodialysis. The mean age of the patients was 45 years (range 6 to 62 years). We evaluated the effects of various factors for patency rates in the patients who had primary arteriovenous fistulas. Primary patency was defined as the duration of fistula patency without revision. Twenty-eight patients (6.7%) with ischemic cardiac disease did not require surgical interference. Analyzed data were age, gender, smoking habits, diabetes mellitus, malignant neoplasm, previous dialysis catheter insertion, number of hemodialysis sessions, and fistula location. RESULTS: In 298 patients, where lower-arm radiocephalic fistulas were created, the fistula patency was 74.1%, 64.2%, 49.8%, 33.7%, and 4.1% after 1, 2, 3, 4, and 5 years, respectively, in the other 114 patients, where upper-arm fistulas were created, these rates were 84.0%, 72.2%, 53.3%, 39.8%, and 12.3%, respectively. There was no significantly difference between the upper-arm fistulas and the lower-arm fistulas statistically (p = 0.069). Factors affecting the primary patency of arteriovenous fistulas were diabetes mellitus (p = 0.0001), hemodialysis counts > or =3 per week (p < 0.0005), presence of malignancy (p < 0.0005), previous catheter insertion (p < 0.0007), and administration of heparin per hemodialysis session (p = 0.0008). CONCLUSION: While primary arteriovenous fistula patency was shortened in chronic renal insufficiency patients with diabetes mellitus, presence of malignancy, and previous catheter insertion, patency was longer in patients with heparin used for hemodialysis and hemodialysis count per week (> or =3).

Role of closed mitral commissurotomy for mitral stenosis: mid- and long-term surgical outcome of 36 patients.

PURPOSE: To evaluate long-term survival and valve-related complications as well as prognostic factors for mid- and long-term outcome after closed mitral commissurotomy, covering a follow-up period of 14 years. MATERIAL AND METHODS: Between 1989 and 2003, 36 patients (28 women and 8 men, mean age 28.8 +/- 6.1 years) underwent closed mitral commissurotomy at our institution. The majority of patients were in New York Heart Association (NYHA) functional class IIB, III, or IV. Indication for closed mitral commissurotomy was mitral stenosis. Closed mitral commissurotomy was undertaken with a Tubbs dilator in all cases. Median operating time was 2.5 hours +/- 30 minutes. RESULTS: After closed mitral commissurotomy, the mitral valve areas of these patients were increased substantially, from 0.9 to 2.11 cm(2). No further operation after initial closed mitral commissurotomy was required in 86% of the patients (n = 31), and NYHA functional classification was improved in 94% (n = 34). Postoperative complications and operative mortality were not seen. Follow-up revealed restenosis in 8.5% (n = 3) of the patients, minimal mitral regurgitation in 22.2% (n = 8), and grade >or=3 mitral regurgitation in 5.5% (n = 2) patients. No early mortality occurred in closed mitral commissurotomy patients. Reoperation was essential for 5 patients following closed mitral commissurotomy; 2 procedures were open mitral commissurotomies and 3 were mitral valve replacements. No mortality occurred in these patients. CONCLUSIONS: The mitral valve area was significantly increased and the mean mitral valve gradient was reduced in patients after closed mitral commissurotomy. Closed mitral commissurotomy is a safe alternative to open mitral commissurotomy and balloon mitral commissurotomy in selected patients.

Left ventricular pseudoaneurysm after myocardial infarction.

In this report, a case of a left ventricular (LV) pseudoaneurysm due to a previous myocardial infarction, which was repaired successfully, is described. A 62-year-old man, with a history of acute anterior wall myocardial infarction 6 months previously, was admitted with the complaints of acute dyspnea and palpitation. Echocardiography revealed an LV aneurysm, and ventriculography showed ventricular dysfunction and an LV pseudoaneurysm. Coronary angiography showed total occlusion of the proximal segment of the left anterior descending artery with a very thin lumen and insufficient retrograde filling. Under cardiopulmonary bypass and beating heart, the pseudoaneurysm was resected and the defect on the ventricular free wall was closed by the remodeling ventriculoplasty method of Dor. Histopathologic examination of the resected material confirmed the diagnosis of pseudoaneurysm. The postoperative course of our patient was uneventful. He was discharged on the ninth postoperative day.

An evaluation of histomorphometric properties of coronary arteries, saphenous vein, and various arterial conduits for coronary artery bypass grafting.

PURPOSE: We evaluated the histomorphological properties of the coronary arteries, saphenous vein, and five arterial conduits for coronary artery bypass grafting, and compared them with each other. METHODS: All vessels were harvested from seven cadavers, eight autopsied individuals, and 14 patients. The length, lumen diameter, wall thickness, and histological structures were examined based on samples obtained from the coronary arteries and the conduits. The dimensions and wall thicknesses of the coronary arteries and the conduits were compared using a one-sided variance analysis. The similarities between the coronary arteries and the conduits were investigated by Duncan's multiple range tests. RESULTS: The internal mammary and intercostal arteries were elastic, while the others were muscular. The lengths of all conduits were adequate for use as coronary artery grafts. The dimensions and wall thicknesses of the coronary arteries and the conduits showed no statistically significant differences, except for the proximal portion of the saphenous vein. CONCLUSIONS: These findings emphasize the justification of continued use of the ideally matching internal mammary artery, either as an in situ or free graft, in coronary artery bypass grafting, although other arterial grafts can be used in coronary artery bypass grafting. In addition, the intercostal artery was found to have relatively favorable properties regarding its potential suitability as a coronary bypass conduit.

Influence of cardiovascular risk factors on the outcome of coronary artery bypass surgery.

PURPOSE: To assess the impact of gender, age, and other cardiovascular risk factors on the outcomes of patients undergoing coronary artery bypass grafting (CABG). METHODS: A total of 5067 consecutive patients undergoing isolated CABG between 1995 and 2000 were divided into the age groups: 25-49 years, 50-59 years, 60-69 years, and 70-84 years. Data on patient age, gender, smoking, serum cholesterol, blood pressure, body mass index, diabetes, family history, morbid obesity, and renal failure were retrospectively analyzed. RESULTS: The percentage of women aged > 60 years undergoing CABG was higher than the percentage of men aged > 60 years (45.6% vs 36.6%). Most of the cardiovascular risk factors, except for smoking, were favorable in women (P < 0.001). The in-hospital mortality was 2.0% in women and 1.7% in men (P = 0.409). CABG was performed on significantly more men than women, accounting for 80.7% and 19.3% of the 5067 patients, respectively (P < 0.001). However, the incidence increased remarkably in women aged > 60 years. CONCLUSIONS: The risks of CABG may vary to some degree in accordance with the major cardiovascular risk factors. The risk of operative mortality was independent of gender in this study.

Involvement of the coronary artery in a patient with thromboangiitis obliterans. A case report.

We report a case of coronary artery bypass grafting (CABG) using the left internal mammary artery (LIMA) and a saphenous vein graft in a 36-year-old man with Buerger's disease. He was hospitalized in the coronary intensive care unit with a diagnosis of acute myocardial infarction. His coronary angiography showed total occlusion of the proximal segment of the left anterior descending artery (LAD) and right coronary artery. Left ventricular dysfunction was detected by ventriculography. The patient had undergone bilateral sympathectomy of the lumbar branches for distal arterial occlusions due to thromboangiitis obliterans 12 years previously. Under cardiopulmonary bypass and aortic cross-clamping, we performed endarterectomy and a complex bypass procedure to LAD. Aorta-right coronary artery bypass was also applied. A histopathological study of an endarterectomy specimen showed characteristic features of thromboangiitis obliterans. The postoperative course was uneventful and the patient was discharged on the ninth postoperative day.

Arterial embolism caused by a ruptured hydatid cyst in the heart: report of a case.

Cardiac hydatid cysts are extremely rare and, although patients may remain asymptomatic for many years or have only minor nonspecific symptoms, they are associated with life-threatening complications. We report the case of a 32-year-old woman with an acute arterial embolism caused by a ruptured hydatid cyst in the heart. An emergency operation revealed that the embolism originated from the left cardiac chamber caused by a cyst in the left ventricle. There were also three cystic lesions in the right lung. The patient underwent surgery to remove the hydatid cysts from the right lung on the 13th day after the first operation. Her postoperative course was uneventful and she was discharged from hospital on the 27th day after admission.

Comparison of the topical haemostatic agents for the prevention of suture hole bleeding. An experimental study.

OBJECTIVE: using a rabbit vascular graft model we investigated the use of fibrin glue (FG), gelatin-resorcinol-formaldehyde (GRF), and collagen (C) as a means of reducing suture hole bleeding. MATERIALS AND METHODS: twenty-eight rabbits were divided into four groups: fibrin glue, gelatin-resorcinol-formaldehyde, collagen and control. A 1 cm incision was made in the abdominal aortic wall of each animal. Incisions were covered with a polytetrafluoroethylene patch sutured with a 7-0 polypropylene. Fibrin Glue, GRF, and C were applied to cover suture holes in the groups 1, 2 and 3, respectively, but nothing in controls (group 4). The fibrin clot was allowed to achieve strength for 3 minutes before the clamps were reopened. After reopening the clamps, blood was collected from the surgical site using a syringe for a total of 2 min. RESULTS: mean blood loss was significantly lower in the FG, GRF, and C compared with control group (p=0.0022, p=0.0022, and p=0.0017, respectively). The volume of blood lost and the time of haemostasis in the group 1 (FG) was less than those in groups 2 and 3 (GRF and C, respectively) (p=0.001). The haemostasis (defined 2 min later) was achieved only in group 1 (FG) (p=0.00067). CONCLUSIONS: FG, GRF and C all reduce blood loss. Fibrin glue containing factor XIII was the most effective.

[Replantation in the complete amputation of the upper extremity].

Trauma of the upper extremity can be a cause of significant morbidity and disability to otherwise productive people. Wounded extremity can be saved by replantation of the amputated parts. Replantation of traumatic amputations can be performed with reasonable success at a regional medical center when experienced surgeons, appropriate and experienced equipment, and skilled ancillary care are available. Successful replantation significantly reduces the morbidity of upper extremity amputations. We presented one case that, 9 year-old, was bridged to our hospital because of total arm amputation after sustained during use of a lawn mover. His arm was saved by urgency surgery.
