Embolization of extensive peripheral angiodysplasias. The alternative to radical surgery.

We describe two patients with extensive pelvic and lower limb angiodysplasias, in whom hemodynamic complications subsequently developed. These have been treated by selective angiography and multiple percutaneous transcatheter embolizations with satisfactory results (1 1/2 to four years of follow-up). One patient had had three previous operations with no improvement; amputation was the only surgical alternative. In the other patient, hip disarticulation and hemipelvectomy was seriously considered because of cardiac failure not responding to medical therapy. We review the literature and use our cases to illustrate points of technique and reemphasize the essential role of therapeutic embolization in the management of extensive angiodysplasia.
