D. The interval to reperfusion limits their utility in the treatment of advanced ischemia.

DISCUSSION: The balloon catheter technique for embolectomy and thromboembolectomy was introduced in 1963. Lytic agents were undergoing clinical investigation at that time. Streptokinase, derived from streptococci, is antigenic. Urokinase is a naturally occurring enzyme and is not antigenic. Lytic agents have yet to play a major role in the treatment of advanced ischemia in the periphery because of delayed reperfusion, cost, risk of complications, the danger of increased tissue loss.
