Distal arm and hand ischemia from vessel thrombosis or embolism remains a difficult clinical challenge. The causes of ischemia are variable and include connective tissue disease, embolism, atherosclerosis, and iatrogenic etiology. Although reports are limited, treatment with catheter-directed thrombolysis has favorable results in cases of acute thrombosis, with most patients (80%) demonstrating improvement. Digital amputation rates are less than 10% and the hand is often salvaged. Bleeding and access-site complications remain prevalent in patients undergoing intra-arterial thrombolysis. This review discusses etiology, treatment approaches, outcomes, and complications when thrombolytic therapy is used for distal arm and hand ischemia.
