Accelerated atherosclerosis, aneurysmal disease, and aortitis: possible pathogenetic association with cocaine abuse.

Cocaine abuse and its association with vascular disease has become common in the medical literature. A variety of vascular problems have been described including neurovascular complications, cardiovascular complications, aortic dissection, venous thrombosis, mesenteric artery thrombosis, and renal infarction. The pathogenesis of these vascular complications has largely been related to increased adrenergic activity leading to vasospasm. Interaction of cocaine with the vascular endothelium resulting in thrombosis or vasculitis has also been suggested. We report a case of diffuse aneurysmal change of the aorta associated with an atypical inflammatory component consistent with possible cocaine induced vasculitis.
