[Early experience with self-expanding flexible stent for the treatment of atherosclerotic diseases in the popliteal artery].

Introduction: The incidence of peripheral arterial diseases and the rate of chronic limb-threatening ischaemia are increasing year by year. Minimally invasive peripheral interventions have gradually replaced traditional operations. Earlier steno-occlusion of the popliteal artery was an indication for femoropopliteal bypass below the knee. Nowadays, endovascular procedures are also used, but the indication of the stent placement into the popliteal artery is controversial. Aim: We have been using Jaguar stent for the treatment of popliteal artery steno-occlusion since January 2016. The aim of our study was to evaluate the efficacy of this treatment. Method: We included patients who underwent popliteal artery angioplasty with Jaguar stent placement between 1 January 2016 and 31 December 2017 in our department. During the one-year follow-up, we examined the popliteal stent patency, amputation-free survival and risk factors that influence stent patency. Statistical analysis: For the comparison of mean values, two-sided t-tests were used. Categorical data were analyzed by using chi-square test. Results: 33 patients underwent popliteal or femoropopliteal endovascular intervention with Jaguar stent placement into the popliteal artery. Postoperative complications that required surgical treatment occurred in 2 patients. At the end of the follow-up, the primary patency of the popliteal stents was 58.1%, the secondary patency was 74.2% and amputation-free survival was 96.8%. Conclusion: Compared with international data, the primary patency of the Jaguar stents in our study is relatively lower, but amputation-free survival is much better, and in most cases there is less operative strain compared with traditional operations.
