Fatal lipid embolism following intraarterial angiography at an early stage of arteriosclerosis.

Abstract

Intraarterial angiography was performed on a patient with peripheral arterial occlusive disease (Fontaine IIb). No relevant risk factors were known, and a previous angiography had been undertaken without incident. After administration of contrast medium, the patient complained of acute pain in the lower abdomen and both legs, and a sudden rise in blood pressure was observed. The patient subsequently lost consciousness and died within 1.5 h. Postmortem examination showed that death was due to peripheral atheromatous microembolism of lipids, and not cholesterol as is usual in these cases. The differential diagnosis is discussed and a review of the literature is presented.
