Selective stenting in subintimal angioplasty: Analysis of primary stent outcomes

Abstract

Selective stents placed for suboptimal results after subintimal angioplasty produce similar patency rates to primary SIA without stents. Patients receiving stents with prior lower extremity bypass surgery will have worse outcomes than those without. Use of a stent diameter < or =6 mm and indication of critical limb ischemia will likely produce worse results. It appears that other stent variables (location, number, length, and overlap) do not alter patency. Finally, selective stent use after SIA provides excellent limb salvage.

Subintimal angioplasty of chronic total occlusion in iliac arteries: A safe and durable option

“…8 Type and number of stents used were also at the judgment of the individual surgeon. When bilateral common iliac artery lesions were treated, a kissingballoon technique was utilized, otherwise, a unilateral balloon was utilized.…”

Subintimal Angioplasty of Long Chronic Total Femoropopliteal Occlusions: Long-Term Outcomes, Predictors of Angiographic Restenosis, and Role of Stenting

“…However, predictors for better angiographic patency after SIA have not been adequately investigated so far. In addition, the role of bare stent or stent-graft placement during subintimal recanalization of chronic total occlusions (CTOs) has been only touched on [12][13][14][15]. The investigators herein report the results of a prospective single-center registry with the aim to investigate the immediate result as well as the longterm clinical and angiographic outcome of SIA plus bailout stenting for the treatment of chronic total occlusive atherosclerotic disease of lesions located in the SFA and/or PA.…”

Comparison of Clinical outcomes of Infragenicular Angioplasty between diabetic and non-diabetic patients with Peripheral Arterial Occlusive Disease

“…However in other study by Schmieder & colleagues [42] in the patients underwent subintimal angioplasty of the femoral and popliteal arteries, one-year 1ry and 2ry patency for angioplasty plus stenting group versus angioplasty alone group was 50% vs. 45% and 70% vs. 78%.…”
