Rupture of abdominal aortic aneurysm into the inferior vena cava: a study of seven cases.

The authors report seven cases of abdominal aortic aneurysm rupturing into the inferior vena cava system. Symptoms were protean, but included local clinical manifestations and general findings due to the high-flow arteriovenous fistula. In spite of different types of clinical presentation, the correct preoperative diagnosis was made when a continuous bruit with systolic accentuation was heard over the abdomen.

[165 bilateral atherosclerotic carotid occlusive lesions. Surgical and secondary risk].

Operative treatment was applied in 139 patients with hemodynamically significant bilateral stenosis of the carotid arteries due to atherosclerosis. Three groups could be distinguished: group I--stenosis greater than 75% on one side and between 50 and 75% on the other side; group II--stenosis greater than 75% on both sides; group III--obstruction on one side and stenosis greater than 50% on the other side. The risk of clamping did not appear abnormally high, while the peroperative neurologic risk was slightly enhanced due to the possibility of accidents in the region which lies contralateral to that of the operated side, or in the region of the brain stem.
