[Preoperative evaluation of arteriosclerotic symptoms in the lower extremities by means of intravenous digital subtraction angiography].

Intravenous DSA was performed in 106 patients with symptoms of arterial insufficiency in the lower extremities, requiring treatment according to preceding clinical examination. The examinations were carried out using a 36.5 cm (14 in.) intensifier and a 5.5 F pigtail catheter located centrally. 71% of the examinations were carried out on out-patients. No complications were observed. In 96% of the cases, the intravenous DSA provided sufficient information to make decisions about treatment.
