Fibrinolytic therapy for upper-extremity arterial occlusions.

Abstract

Acute upper-extremity arterial occlusion may be due to embolic phenomena or de novo thrombosis. If the occlusion is left untreated, claudication or ischemia necessitating amputation can occur. Operative Fogarty-balloon embolectomy has been the treatment of choice for this entity. In a 6-year period the authors used fibrinolysis on nine occasions in eight patients to treat acute upper-extremity arterial occlusions. Concomitant balloon angioplasty was helpful in four cases. Success, defined as a normal hand with at least one artery that was continuously patent to the wrist, was achieved in all patients. A single significant groin hematoma was seen. Neither stroke nor death occurred in any case, and no amputations were necessary. Local transcatheter intraarterial administration of urokinase can be considered a first-line treatment for brachial artery embolus and other causes of acute upper-extremity arterial occlusion.
