BACKGROUND: The aim of the present study was to assess the mid-term patency rate of @entity5648 stent implantation in @entity1 with long superficial femoral artery (SFA) @entity850 or @entity432 . This is a retrospective, single-center study. METHODS: The data of 138 @entity1 were retrospectively assessed in our center to determine the patency rate after @entity5648 stenting of the SFA. MATERIALS: Data for 165 limbs from 138 @entity1 were collected. Each limb showed a long lesion with a total @entity432 of >10 cm and mean lesion length of 20.35    9.46 cm (range, 10-32 cm). @entity5648 self-expanding stent implantations were performed in each limb. A total of 258 stents were implanted into 165 limbs (average, 1.56 stents/limb). Each @entity1 received clinical and ultrasound/computerized tomographic angiography/magnetic resonance angiography evaluations before the procedure and underwent clinical status evaluation and an ankle-brachial index test at discharge and at 12, 24, and 36 months thereafter. RESULTS: The initial technical success rate of revascularization was 91.51% (151/163). During follow-up, nine @entity1 died because of @entity583 , @entity385 , and @entity55 , and 14 @entity1 were lost to follow-up. The mean follow-up period for 150 limbs from 124 @entity1 was 25.46 months (range, 6-51). During follow-up, 19 in-stent restenoses and 15  occlusions were diagnosed. In all, 30 re-interventions were performed, including six balloon angioplasties, three secondary cutting balloon angioplasties, 10 restenting procedures, four bypass surgeries, two bone marrow stem cell transplantations, and five limb amputations. Analysis showed the primary patency rates at 12, 24, and 36 months were 92.4%, 78.3%, and 62.1%, respectively, and the overall assisted-primary patency rates were 94.4%, 84.6%, and 75.8%, respectively. CONCLUSIONS: @entity5648 self-expanding stent implantation seems to be a good choice for older @entity1 with long SFA occlusions. Although the short- and mid-term patency results were good, more observations are needed to assess its long-term efficiency.
