Objective This study aimed to evaluate the safety and the efficacy of primary stenting to treat Trans-Atlantic Inter-Society Consensus II (TASC) D femoropopliteal lesions.
Background Advances in wire, balloon and stent design have been reported to improve the durability of stenting of longer femoropopliteal lesions.
Methods A total of 57 limbs of 53 patients with Rutherford stage 3 to 6 due to TASC D femoropopliteal lesions were treated with a self-expanding nitinol stent in a prospective, single-centre, observational study. End points of interest included primary and secondary patency, target lesion revascularization, in-stent restenosis, major adverse cardiovascular events, Rutherford class improvement and change in walking capacity at 1 year.
Results A total of 53 patients (57 lesions) were treated with a self-expanding nitinol stent and final procedural success was 91.2%. The median length of the treated segment was 330 ± 96 mm. The median stented segment was 366 ± 71 mm and the mean number of the stents was 2.1 ± 0.9. At 1 year, primary and secondary patency rates were 63.9% and 82.1%, respectively. Major adverse cardiovascular events occurred in 11 patients (22.9%), and[[strike_start]] [[strike_end]]significant benefits were observed in Rutherford class and walking distance (both P < 0.001).
Conclusions Primary implantation of self-expanding nitinol stents for the treatment of TASC D femoropopliteal lesions appears to be safe and effective, especially in patients who have multiple co-morbidities and a high risk for surgical bypass. The risk of restenosis was higher when long stenting was extended to the popliteal artery.
