Secondary rupture of an iliac artery aneurysm after exclusion-bypass.

We report a case of secondary rupture of a common iliac artery aneurysm into the common iliac vein. Exclusion of the iliac aneurysm had been performed 2 years earlier in association with reconstruction of an aortic aneurysm that had ruptured into the interior vena cava. After closure of the aortocaval fistula by the endoaneurysmal route, aortobifemoral bypass grafting had been performed and a caval clip had been placed.

[Atheromatous pseudo-occlusive stenosis of the internal carotid].

Pseudo-occlusion of the internal carotid artery is defined as an angiographically occluded but anatomically patent artery. Between january 1980 and december 1990, 14 cases were diagnosed in our institution. Preoperative Doppler examination of the internal carotid artery suggested almost complete thrombosis in 11 patients and occlusion in 3.

Persistent hypoglossal artery.

During embryological development, the hypoglossal artery serves as a transient anastomosis between the internal carotid artery and the vertebro-basilar system. This artery occasionally persists into adult life. Two cases of persistent hypoglossal artery we have recently encountered are reported here.

Hydronephrosis after aortofemoral bypass graft. A prospective study.

This prospective study was designed to determine the frequency and natural history of hydroureteronephrosis (HUN) after placement of an aortobifemoral vascular graft. A total of 30 patients were evaluated by the study protocol, which included: pre and postoperative biological kidney function tests, preoperative and early postoperative (14th day) intravenous pyelograms and a late (mean 18th month) urologic examination by renal ultrasonic tomography. Four asymptomatic, early cases of HUN were observed in the 57 ureters examined (7%); all four complications regressed in less than 30 days.

Carotid endarterectomy plaques: correlations of clinical and anatomic findings.

To establish possible relationships between the structure of carotid plaque and neurologic symptoms, 187 consecutive endarterectomy specimens were studied prospectively. Each specimen was examined for gross and histopathological features. Intraplaque hemorrhage, although found infrequently, was closely correlated with the presence of symptoms.
