[Clinical case of the month. Popliteal artery entrapment syndrome: a cause of non-atherosclerotic arteriopathy in a young patient].

Popliteal artery entrapment syndrome is one of the most frequent causes of non atheromatous arteriopathy among young people without any vascular risk factor. The physiopathology is an extrinsic compression of the artery by muscular structures. It is important to make the right diagnosis because surgery is the only treatment.

["Isolated" thrombi of the aorta: retrospective study of 10 observations].

Introduction: Thrombi of the aorta are mostly linked to atheromatous plaques on the aortic wall of patients with classical risk factors for cardiovascular disease. The thrombus rarely appears on sound arteries and in this case is called "isolated".

Methods: We present a retrospective study of ten patients with "isolated" thrombi of the aorta treated between 1995 and 2004 at the Hospital of Grenoble.

[Digital ischaemia and gemcitabine. Two new cases].

Chemotherapy generates numerous adverse effects, but digital ischemia is usually associated with a paraneoplastic mechanism. In addition to thrombotic microangiopathy or hepatic or pulmonary venoocclusive disease gemcitabine appears to induce this type of complication. This study presents two cases of digital ischemia, which are very likely attributable to gemcitabine.
