Cocaine-associated dissection of the thoracic aorta

Patients present to emergency departments with a variety of complications related to cocaine abuse. Emergency physicians must be aware of the life- and limb-threatening complications to avoid undue mortality and morbidity. We present the case of a patient with aortic dissection who developed the acute onset of abdominal pain 5 minutes after subcutaneous cocaine use. Four previous reports of cocaine-associated aortic dissection are reported in the literature. These cases and other reports of intra-abdominal vascular injuries related to cocaine use are reviewed. Cocaine's mechanism of action as it relates to aortic dissection and some of the pharmacologic agents available for treatment are discussed.
