Abstract

Objective The role of endografts in the treatment of extensive superficial femoral artery (SFA) occlusive disease is enlarging. Results are limited by the occurrence of edge stenosis. The aim of the study was to retrospectively evaluate the efficacy of treatment of edge stenosis of endografts inserted for SFA occlusive disease. Methods All patients, treated between November 2001 and December 2011, with a self-expandable polytetrafluoroethylene-endograft were gathered in a prospective database in three hospitals. The incidence of primary edge stenosis and the incidence of re-edge stenosis after treatment were retrospectively noted and a comparison was made between the results of percutaneous transluminal angioplasty (PTA) and extension of the endograft. Results A total of 88 patients presented with 115 edge stenoses, of which the majority presented within 1 year after insertion of the endograft (mean time to edge stenosis 10.7 ± 8.2 months). Seventy-three stenoses (63%) manifested at the proximal and 42 at the distal edge (37%). The 1-year incidence of restenosis and/or occlusion was 45% after PTA and 43% after endograft extension, with 1-year patency rates of 81% and 92%, respectively. The incidence of restenosis/occlusion after treatment with PTA was 12% higher at two years compared to extension of the endograft (55% vs. 43%, respectively). Conclusion Edge stenosis may well be treated with either PTA or extension of the endograft. The incidence of restenosis and/or occlusion after both PTA and extension is high, but patency rates are acceptable. Aggressive surveillance is needed during the first year after insertion.
