[Persistent sciatic artery: possible false negative imaging].

Persistent sciatic artery is a rare congenital malformation due to the lack of regression of the dorsal arterial axis of the embryo that can be revealed by serious complications. We report a case of bilateral persistent sciatic artery revealed by subacute distal ischemia. This case illustrates the possibility of false negative imaging and the importance of ruling out this diagnosis in case of recurrent and apparently idiopathic distal embolism.

Objectifying exercise ischemia in peripheral vascular disease: a study in 120 patients.

This study presents the results of transcutaneous oxygen pressure (TcPO2) monitoring during a treadmill test walk performed in the early stages of peripheral obliterative vascular disease. The study population consisted of a first group of 50 known arteriopathic patients presenting, on questioning, with intermittent claudication; a second group of 50 known arteriopathic patients void of any symptoms of intermittent claudication; and a third group, which was a control cohort of 20 nonarteriopathic, nonclaudicating patients. Though resting TcPO2 cannot be used to aid the clinical diagnosis of exercise ischemia it may be useful in revealing asymptomatic chronic resting ischemia (9% of cases in this series).

Tuberculous aneurysm of the femoral artery: a complication of bacille Calmette-Guérin vaccine immunotherapy--a case report.

A case of bilateral femoral mycotic aneurysms resulting from bacille Calmette-Guérin vaccine, is reported in a 74-year-old man treated by intravesical immunotherapy. The diagnosis was made after histologic and bacteriologic examinations and biochemical analysis of the acid-fast-baccilli. Treatment consisted of resection and replacement of the femoral arteries, with an expanded polytetrafluoroethylene graft on the left side and a saphenous vein graft on the right side.

[Mesenteric and retroperitoneal fibrosis. A case report. Review of the literature].

The authors report a case of combined mesenteric and retroperitoneal fibrosis resulting in vascular and digestive compressions. Diagnosis was established by laparoscopy and biopsy. No etiologic factors were found.
