Stenting as a bail-out option after failed percutaneous transluminal angioplasty in infrainguinal vein bypass grafts.

<bold>Objectives: </bold>To study the safety and efficacy of bare and covered stents in infrainguinal vein grafts after failure of PTA for treating graft stenoses.<bold>Methods: </bold>An analysis of a prospective database of all patients who underwent stenting of infrainguinal vein bypass grafts at this institution between 1 January 2008 and 31 December 2012 was carried out. The main outcome considered was primary patency, which was reported at 1, 6 and 12 months.<bold>Results: </bold>A total of 18 patients with a mean age of 73 years (range: 56 to 86) were included. The indications for stent placement were significant recoil (7, 39%), graft rupture (6, 33%), residual vein cusps (3, 17%) and aneurysmal degeneration (2, 11%). There was a high overall technical success rate of 94% (17/18) and arrest of haemorrhage was achieved in all cases of graft rupture. The primary patency at 1, 6 and 12 months was 89%, 71% and 59%, respectively.<bold>Conclusion: </bold>The use of bare and covered stents in infrainguinal vein grafts appears safe and effective. They are an excellent bail-out option for the treatment of graft rupture and give acceptable short-term results. [ABSTRACT FROM AUTHOR]
