A dual-purpose angioplasty-drug infusion catheter for the treatment of intragraft thrombus.
An investigational angioplasty-drug infusion catheter (Transport, CardioVascular Dynamics, Irvine, CA) was used to treat a saphenous vein graft stenosis associated with a thrombus. The catheter was successfully used both to infuse urokinase at the site of angioplasty and to perform effective angioplasty, demonstrating the feasibility and utility of a dual-purpose angioplasty catheter capable of angioplasty and/or local drug infusion with the same catheter.
