Two cases of vein patch blowout were observed five and seven days after carotid bifurcation endarterectomy with patch angioplasty. Both patients died in spite of emergency reoperation. One patient developed respiratory failure with subsequent fatal cardiac arrest seven days after reoperation; the other died of extensive hemispheric infarction on the fifth postoperative day. At reoperation both ruptures were found to be located in the middle of the patch whereas the suture lines were intact. Both patients were hypertensive. In the first case, an accessory saphenous vein retrieved from the calf had been the only venous material available for the patch, while the other patient had varicose veins in the contralateral leg. Pathology revealed central transmural tissue necrosis in one of the disrupted patches. A review of the literature regarding morphologic alterations of free vein grafts placed within the arterial circulation as well as hemodynamics in patched arterial segments may provide additional insight as to the inherent benefits and risks of vein patch angioplasty after carotid endarterectomy. When considering vein patch angioplasty, particular attention should be directed to the gross aspect of the vein to be used as well as to any antecedent history of phlebitis. [less ▲]

We present one case of arterial hypertension that had rapidly developed in a 23-year-old patient. Arteriography demonstrates a light stenosis of the root of the right renal artery and an obstruction of the superior mesenteric artery. After an attempt of intraluminal dilatation had failed, we decided to carry out double revascularization with a venous graft. Postoperative control arteriography demonstrated early thrombosis in both grafts. Our second operation directly approached the lesion on the root of the renal artery, which was stenosed by muscle fibers from the right column of the diaphragm muscle. The resection of these fibers released the renal artery, which was otherwise normal, as was confirmed by the postoperative arteriogram. In a second part, we discuss the etiology of this double stenosis and our surgical strategy. [less ▲]

We report two recent observations of giant hemangiopericytoma of the lung, one in a 4-year-old child and another in a 65-year-old man. There were no specific clinical signs, but the radiologic appearance was rather characteristic in both cases, as were the histologic findings. Pneumonectomy was carried out, complicated in each case by rupture of the fragile, incomplete pseudocapsule and diffuse dissemination of necrotic tumor tissue in the operative field and opposite bronchial tree. Outcome was fatal in both cases within a few months, with extensive, rapidly growing metastases in the subcutaneous scar tissue of the thoracotomy and in the other lung and in one case with diffuse diaphragmatic and intraabdominal metastases. These two observations will offer some guidelines for better understanding of this rare localization of hemangiopericytoma, its natural history, and its optimal treatment, with special reference to the malignant potential and local recurrence rate.

From 1981 to 1987, 29 patients (14 women and 15 men, with a mean age of 56 +/- 15 years) underwent a carotid-subclavian bypass for occlusive lesion of the subclavian artery (or of the left common carotid artery). The symptomatology included vertebrobasilar insufficiency, arm ischemic symptoms, or combination of both symptoms. Twelve patients (42%) have had a previous transient ischemic attack, or a cerebrovascular accident. There were 22 stenoses or occlusions of the left subclavian artery, and 6 of the right subclavian artery. On arteriography, 9 patients had significant associated lesions on the internal carotid artery, either homolateral (n = 7), or heterolateral, or bilateral. Carotid to subclavian bypasses were performed either with autogenous saphenous vein (n = 15), or with prosthetic graft (n = 14). In 5 cases, a carotid endarterectomy was done simultaneously to the bypass. Operative mortality was 3.4% (1/29). Early patency (less than 1 month) was 97% and late patency 89%, with a mean follow-up of 40 +/- 24 months. The patency rates were not significantly different whether a prosthesis or a vein was used for the bypass. All patients were improved and complete relief of symptoms was achieved in 92%. No patient experienced symptoms of carotid steal after the bypass. We concluded that carotid-subclavian bypass is a safe and efficient method for revascularization of the subclavian artery of of the left common carotid artery in selected cases. [less ▲]

A series of 73 simultaneous carotid and coronary revascularizations (Group I) is presented (January 1980-December 1988). Age, sex, risk factors, severity of angina, coronarography, neurological symptoms, angiographic carotid lesions and operative outcome of these 73 patients are compared with the aspects of 3544 coronary bypass patients (Group II) and 1001 carotid endarterectomized patients (Group III) during the same period. The angina in Group I is more severe, with 22% belonging to NYHA class IV and 26% having a stenosis of the left main coronary artery, vs 14% and 13% in Group II. Seventy percent of the carotid lesions in Group I are asymptomatic vs 33% in Group III. Group I patients had more problems in the perioperative period, with 16.4% needing prolonged high-doses analeptics and 5.4% intraaortic counterpulsation balloon. Operative mortality is higher (7%) in Group I compared with Group II (2.3%) and Group III (1.7%). These results permit to define a population of polyvascular patients with concomitant coronary and carotid disease, characterized by a more diffuse atherosclerosis and a higher operative risk. Operative morbidity and mortality after combined myocardial and cerebral revascularization remains nevertheless inferior to the cumulated surgical risk of the sequential procedures (74 patients with coexistant coronary and carotid lesions operated in two sessions before 1986).

From June 1976 to June 1989, 138 previously revascularized coronary patients were reoperated upon. This represents 3.28% of all aortocoronary bypass procedures performed during the same period in our institution. Characteristics of this group, risk factors, coronarographic data, perioperative morbidity and mortality are analyzed and compared to the data of the general population undergoing bypass surgery. The mean age of individuals requiring reoperation was 59 years. The mean interval between the two operations reached 73 months (5 to 180 months). Angiographic lesions were more extensive with three-vessel disease in 65% of the reoperated patients. The mean ejection fraction was 55%. A mean of 2.1 bypass grafts per patient were inserted with 60% of cases having an internal mammary artery graft. Perioperative infarction occurred in 8.0% of the reoperations and an intraaortic balloon counterpulsation was necessary in 4.3% at the end of the procedure. Operative mortality was 5%. Symptomatic improvement was obtained in 85% of the cases. In recent years, cardiac transplantation has been performed for 11 previously bypassed patients with severely impaired ventricular function. There were no postoperative deaths. Cardiac transplantation can be considered as a more valuable alternative to repeat coronary artery bypass grafting in such cases. [less ▲]

The authors report their recent experience with renal autotransplantation (3 cases). In one case it concerned a complex aneurysm of the renal artery involving secondary arterial renal branches, and associated with hydronephrosis (case 1); another patient presented a high ureteral injury unsuccessfully repaired by previous surgery (case 2), and the third patient had diffuse fibrodysplasia of intrahilar arterial branches (case 3). The procedures were technically successful and gave good functional results. They describe the technique of kidney refrigeration, extracorporeal vessel repair and ureteral preservation or reimplantation. Indications and technical advantages of this organ-saving reconstructive approach are discussed. [less ▲]

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. [less ▲]

Five cases of Marfan's syndrome with cardiovascular lesions are presented. Among these five patients, two with type I aortic dissection, one with true aneurysm of the ascending aorta and one with aortic regurgitation underwent composite grafting of the ascending aorta according to the Bentall technique. The fifth patient died preoperatively, due to extensive dissection of the transverse aorta. Marfan's syndrome is transmitted in an autosomal dominant manner. Fifty percent of the patients die at a mean age of 32 years, and 95 p. 100 of the deaths are caused by cardiovascular lesions. These lesions predominantly affect the left cardiac valves (aortic or mitral regurgitation) and the ascending aorta. Except in emergencies, replacement of the ascending aorta by a composite graft must be envisaged in subjects with Marfan's syndrome presenting with aortic regurgitation and dilatation of the aortic root.

We report the case of an infected aneurysm of the abdominal aorta in a 18 month-old child, discovered by routine palpation of the abdomen during hospitalization for pneumonia. Ultrasonography and arteriography showed a 6 cm aneurysm of the abdominal aorta beginning distal to the renal arteries which occluded the right common iliac artery. The aneurysm was treated by interposing a 6 mm Gore-Tex graft between the infrarenal aorta and the aortic bifurcation. Pathologic examination of the aneurysmal wall demonstrated a leukocytic infiltrate and the presence of encapsulated Gram positive organisms. Arterial aneurysms are exceedingly rare in children. Their etiology is varied: infection, connective tissue disease, trauma, inflammatory arterial disease or other rare diseases such as tuberous sclerosis, neurofibromatosis, or Behcet's disease.

Polyvascular patients. Among a consecutive series of 4200 patients submitted to vascular surgery, a group of 292 people operated on, in at least two anatomically and physiologically different sites, is individualized as polyvascular patients. A subgroup is characterized by simultaneous procedures in two separated fields; 32 have benefited in the same time from carotid and coronary procedures, i.e., 0.6% of all coronary patients and 2% of all carotid patients. The carotid-coronary group exhibited a more severe anatomical disease both in the carotid and the coronary vasculatures. Apart from simultaneously operated patients, others were sequentially treated over a 7 years period: people with carotid (25%) or visceral (40%) arterial disease were more prone to become polyvascular. Polyvascular patients differ from monovascular patients in that hypertension is more frequent and more severe, mean cholesterol level higher and incidence of severe hypercholesterolemia more frequent.

Between 1977 and 1987, eleven isthmic ruptures and three chronic posttraumatic pseudoaneurysms of the thoracic aorta have been seen in our cardiovascular surgery service. The hemorrhagic intraabdominal wounds were treated first during the same or a staged procedure. Two patients died prior to the vascular intervention. In the other cases, partial femorofemoral extracorporeal circulation has been used after systemic heparinization (3 mg/kg). The perfusion flow was approximately 2 to 3 l/min. Three patients (25%) died following operation. Only one death caused by decerebration is potentially related to heparinization. No paraplegia occurred. The partial extracorporeal circulation is a reliable method to prevent paraplegia and to diminish the left ventricular post-charge during aortic clamp time. [less ▲]
