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.

[Value of axillofemoral bypass in the elderly].

The aim of this retrospective study was to assess the merits of axillofemoral bypass in elderly patients. 69 axillofemoral grafts were laid from 1981 to 1985 in 56 patients, all older than 70. They always were aimed at limb salvage due to aortoiliac obliterating lesions (the indications of sepsis of aorto-bifemoral prostheses have been excluded).

[Behçet's disease with multiple arterial lesions and voluminous hemangioma of the brain].

A case of a 43-years-old patient with a 9-year history of Behçet's disease is reported. The diagnosis was based on the past of bilateral hypopion iritis, oral aphthous ulceration and venous thrombosis. A right lower limb monoparesia occurred.

[Prognosis of acute ischemia of the lower limbs in patients over 80 years of age. A prospective study].

To demonstrate the importance of age in the prognosis of acute lower limb ischemia, a prospective study was performed in 137 patients over 24 months. Group I contained 75 patients aged under 80 years and group II 62 patients aged over 80 years. Risk factors and previous history were equally distributed in the two groups.

Neurologic complications of axillary and brachial catheter arteriography in atherosclerotic patients: predictive factors.

Catheter arteriography by the axillary or brachial route can be responsible for central neurologic complications. The objectives of this prospective study were to define the predictive factors of these complications and determine their incidence. This report is based on 288 consecutive arteriography sessions performed between January 1985 and June 1987.

Human umbilical vein grafts as infrainguinal bypasses: long-term clinical follow-up and pathological investigation of explanted grafts.

This retrospective study examines 105 consecutive infrainguinal bypasses using human umbilical vein (HUV) grafts as blood conduits over a 9 year period. In addition, 39 segments of these grafts were harvested at reoperation and submitted for morphologic, histologic, and scanning electron microscopy examinations. Fifty-two below-knee femoro-popliteal and 53 femoro-distal bypasses were performed in 93 patients.

Synchronous reconstruction for combined aortoiliac and femoropopliteal occlusive lesions. The role of proximal bypass.

Between January 1984 and December 1986, 31 patients underwent synchronous revascularization (SR) because of the serious clinical condition of a lower limb and presence of arteriographically visible lesions. Average follow-up was 30 months. Operative mortality was 10%.

Femorodistal bypass using the chemically processed human umbilical vein graft: 9-year experience.

To evaluate patency, limb salvage rates and complications associated with the use of human umbilical vein as an arterial substitute, the authors carried out a retrospective review of 52 femorodistal bypasses performed over 9 years using human umbilical vein. Indications for operation included acute ischemia, rest pain and nonhealing ulceration or gangrene. There were 28 early occlusions, which resulted in a 1-month primary patency rate of 46% and a secondary patency rate of 52%.

An histo-morphological evaluation of ninety surgically excised human umbilical vein grafts.

Morphological, histological, and scanning electron microscopy examinations were performed on 90 surgically excised human umbilical vein grafts. Most of the explanted grafts were removed because of thrombosis or infection and were removed typically from a patient in the mid 60s and after an average duration of implantation of 11 months. Multiple structural defects were found including deep folds, breaks on the luminal surface, and delamination.

Traumatic fistula between the aorta and the left renal vein: case report and review of the literature.

This report of an aorto-left renal vein fistula (ALRVF) of traumatic origin is the sixth such case on record. The fistula was successfully repaired, with preservation of the kidney, by autotransfusion. Review of the English language literature revealed the differences between spontaneous and traumatic ALRVF.

[Venous involvement in the thoracic outlet syndrome (apropos of 30 cases)].

This paper present 30 patients with subclavian venous compression caused by a thoracic outlet syndrome. 3 stages are differentiated: intermittent compression: 15 patients; acute occlusion: 5 patients; chronic occlusion: 10 patients. Every stage corresponds with a clinic and radiologic unit: venous claudication of the upper limb; phlebitis; post-phlebitis syndrome.

[Chlormetiazole in anaesthesia (author's transl)].

The use of a vitamin derivate (chlormethiazole) in anaesthesia. Owing to its hypnotic properties and its wide margin of safety, "chlormethiazole" (a derivate of vitamin B1) was used in 30 patients which underwent varying surgical procedures. Since the drug exhibits no analgetic effect, fentanyl was added to maintain a sufficient depth of anesthesia.
