Endovascular Treatment of Aortic Arch Vessel Stent Migration: Three Case Reports.

Percutaneous angioplasty and stenting is nowadays the treatment of choice for atherosclerotic stenotic lesions of the supraaortic trunks. Stent migration is a seldom published complication that can alter the short-term results of these procedures. Herein, we report three cases, from three different institutions, of secondary autoexpandable stent migration, after endovascular treatment of major arch vessel stenosis, and their subsequent endovascular management using three different retrieval techniques. Technical success was achieved in all cases. There were no immediate complications related to the retrieval of the migrated stents. A late complication of iliac thrombosis required complementary surgical intervention. Percutaneous retrieval of migrated self-expanding stents is feasible and can be effectively performed with few complications as a first-line option.
