[Revascularization of the lower limbs starting from the descending thoracic aorta].

A rarely reported method for revascularization of lower limbs is the use of descending thoracic aorta and a prosthesis passing through the subpleural and subperitoneal tissues. It is nevertheless a valuable procedure in patients in good general condition in whom there is a local contraindication to the abdominal approach. It appears to be more reliable in the long term than a conventional axillofemoral shunt.

[Popliteal artery thrombosis from an osteochondroma of the upper end of the tibia. Apropos of a case].

A rare case of thrombosis of the popliteal artery due to an exostosis of upper end of tibia is reported. It is rare for exostoses to develop at the upper metaphysial region of the tibia, rare fore vascular complications to develop and particularly rare for these to consist of thromboses. This lesion is a differential diagnosis in young adults with lower limb ischemia. Follow up of these exostoses should be by Doppler, after dynamic arteriography to serve as a reference. Surgical treatment should be adapted to the degree of functional disability and the course of the exostosis or the complications it provokes.

[Crossed iliofemoral bypass].

Crossed shunts between the two femoral axes constitute a useful safeguard in unilateral iliac occlusions when the abdominal approach is contraindicated. Hemodynamic considerations suggest the need for iliac implantation from the donor side. This simple technique does not complicate the operation and provides a more satisfactory result than the interfemoral shunt.

[The anterior tibial artery and vascularization of the muscles of the anterior compartment of the leg. Application to the anterior compartment syndrome of the leg].

The arterial vascularisation of the anterior loge of the leg is supply by the anterior tibial artery. Three muscles are contained in an inextensible space. Each of this muscles received an arterial supply proportional to his volume. The fragility to ischemy of the extensor hallucis longus is not explained by insufficiency of this arterial branches.

[Bypass on a single major artery of the leg. Theoretical modalities and results apropos of 100 cases].

Sub-crural bypass operations on a single leg artery were analysed retrospectively with a follow-up period ranging from six months to eight years. The vitality of the limb was threatened in the majority of cases (91/96). Whenever possible (79/96) the internal saphenous vein was used as a graft, preferably by the in situ technique. Mortality was 6%. Morbidity with the exception of thromboses was 14.5%. Patency by actuarial analysis was 71.6% at 5 years and 65.8% beyond. The majority of thromboses occurred during the first few months and led, in the majority of cases, to amputation. Secondary thromboses were better tolerated. The influence of various parameters was studied: clinical stage, peroperative flowmeter results, material used, technique, associated procedure (sympathectomy), implantation site and permeable vessel.

[Results of surgery in 144 cases for aneurysms of the infra-renal abdominal aorta in patients over 75 years of age].

114 patients aged over 75 underwent surgery for aneurysm of the infra-renal abdominal aorta in the University Teaching Hospitals in Nantes and Angers between 1979 and 1988. A retrospective study of these patients was performed to evaluate the immediate and long-term results. The mean age of the patients was 79 (+/- 4) years, the oldest being 94. 70% were men. Half of the patients underwent emergency or semi-emergency surgery (52 cases). Cardiovascular factors (in particular coronary insufficiency in 17% of cases) were the most common risk factors. In all cases grafting after laying open the aneurysm was performed, with an aorto-aortic graft in 32% of patients, an aorto-iliac graft in 37% or an aorto-bifemoral graft in 27% of patients. Combined intestinal revascularisation was performed in 10% of case either involving the inferior mesenteric artery or at least one internal iliac artery; renal revascularisation was performed in 3.5% of cases. 75% of patients underwent simple grafting. The mean duration of hospitalisation was 14 days (+/- 6), including a mean period of 7 days in ICU. 36 patients (31%) died in the first post-operative month. The mortality rate in patients who underwent emergency surgery for a complication of the aneurysm (essentially rupture) was 61% versus 6' for elective surgery. 96% of the patients who survived the first post-operative month were independent at the end of the study or at the time of their death.(ABSTRACT TRUNCATED AT 250 WORDS)

[Aortic sarcoma. A rare pathology].

In the light of a case of endotheliosarcoma of the thoracic aorta, the authors found in the literature 33 cases of aortic sarcomas and 13 of sarcomas of peripheral arteries. The clinical diagnosis of this rare tumor is difficult. The diagnosis can be made before surgery only on the basis of angiographic and CT scan findings, whilst in most instances common arterial lesions are suspected whether of atheromatous or embolic origin. The positive diagnosis of arterial sarcoma remains histological. The diagnosis of an endothelial tumor can be made with the help of the techniques of factor VIII, antigen H and, more recently, lectins. Surgical treatment by excision and restoration of continuity has most often been used. Alone or in combination with chemo and/or radiotherapy, it would seem to be inadequate to prevent progression which involves the invasion of adjacent tissues, tumor emboli or generalized metastases. The prognosis of such a tumor remains gloomy with an average life expectancy of one year and 7 months, regardless of the histological type of arterial sarcoma.

[Primary aortoduodenal fistula of tuberculous origin].

This case of aorto-duodenal fistula was due to fistulization of a tuberculous lymph node between an atheromatous aneurysm of the infra-renal aorta and the third part of the duodenum. CAT scan provided the diagnosis of an aorto-duodenal fistula. The tuberculous origin of the fistula was confirmed by bacteriological and histological examinations. The outcome was favourable after revascularisation "in situ" combined with epiplooplasty and prolonged antituberculous drug therapy.
