Abstract
Angiographic evaluation of heparin-induced thromboembolism in 3 patients who suffered disastrous consequences revealed a distinctive radiographic appearance consisting of mural filling defects quite unlike atheromatous plaques. These lesions were broad-based, isolated, gently lobulated excrescences which produced 30-95% narrowing of the arterial lumen. In each case, the lesions were located proximal to sites of arterial occlusion. Sodium heparin is considered the anticoagulant of choice for the acute prophylaxis and management of thromboembolic disease.
