Prolonged selective urokinase infusion in totally occluded coronary arteries and bypass grafts: two case reports.

Reports are presented demonstrating a technique for dissolving thrombus in coronary arteries and bypass grafts by using prolonged selective infusion of urokinase via an infusion wire. This allows one to pass a steerable guide wire through the culprit stenosis and perform angioplasty on a distal lesion which could not be previously seen.
