Results of coronary angioplasty using the transluminal extraction catheter

Current techniques for the percutaneous revascularization of totally occluded vein grafts are limited by a low initial success rate, a significant incidence of distal embolization, and a high rate of early graft reclosure. This case report describes two patients in whom graft recanalization was attempted with the combined use of balloon angioplasty/intra-graft stent placement and local urokinase delivery using a new angiotherapy catheter. Successful recanalization was achieved in both patients without major complications, in spite of a large thrombus burden as demonstrated by angiography.

Recanalization of totally occluded saphenous vein grafts using local urokinase delivery with the dispatch^TM catheter

“…However, the presence of thrombus has been associated with lower procedural success and higher acute complication rates than lesions without thrombus . By contrast, TEC atherectomy may be useful for the treatment of thrombus-containing lesions because of its potential ability to cut and aspirate atheroma and thrombus [8,9].…”

Angioscopic guided interventions in a saphenous vein bypass graft

Intracoronary stents appear promising for treatment of focal vein graft lesions, but their use may be limited by the presence of intraluminal thrombus. This report describes the use of percutaneous coronary angioscopy to identify the presence or absence of intraluminal thrombus and to guide interventional therapy with transluminal extraction coronary atherectomy (TEC) and stenting in a patient with a complex vein graft stenosis.

“…This stenosis associated with thrombus could have been treated with other methods, such as the transluminal extraction atherectomy catheter [2], prolonged nonselective systemic or intragraft thrombolytic therapy [3], directional coronary atherectomy, or balloon angioplasty alone. Without a prospective randomized study, it is difficult to determine whether our approach is more beneficial than the alternative methods.…”

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.
