title: Heparin-induced thromboembolism: angiographic features.
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 eache case, the lesions were located proximal to sites of arterial occlusion.
