Steroid anabolic drugs and arterial complications in an athlete--a case history. Serious side effects and complications have been attributed to anabolic and androgenic steroids when used for medical reasons or when taken in sports in hopes of increasing strength and, hence, performance. The author presents a case of an athlete who experienced two metachronous arterial complications after taking these drugs: a cerebrovascular accident caused by a carotid artery thrombus that partially embolized to the brain and, later, a severe ischemic episode in a lower limb caused by a diffused distal arterial thrombosis. This patient represents the first reported case of vascular events in an otherwise healthy athlete taking androgens to increase his skeletal muscle mass.
