Prolonged intragraft urokinase with a new infusion wire: improved short-term results.
Patients with aged saphenous vein grafts and recurrent symptoms of angina are being seen with increasing frequency [Bourassa: J Am Coll Cardiol 17:1081-1083, 1991]. The treatment of these patients remains a dilemma. Direct balloon angioplasty is frequently complicated by distal embolization and early restenosis [Aureran and Gruentzig: Am J Cardiol 53:953-954, 1984]. There is evidence that thrombus plays a significant role in this occlusive process [Hartmann et al.: J Am Coll Cardiol 18:1517-1523, 1991]. Prolonged intragraft urokinase infusion with a new multiside hole infusion catheter debulks thrombus and permits balloon angioplasty without the usual complications.
