Efficacious use of nitinol stents in the femoral and popliteal arteries

摘要: Abstract Objective To evaluate the performance and identify predictors of outcome after use self-expanding nitinol stents in treatment femoropopliteal arterial occlusive disease. Methods A retrospective analysis a prospectively collected database was performed. Outcomes patients who underwent placement stent femoral or above-knee popliteal arteries between 1999 2002 were studied. Patency, limb salvage, patient survival determined by Kaplan-Meier estimation intergroup comparisons log-rank test Cox proportional hazards model. define individual factors associated with clinical outcomes, stepwise regression Results total 41 (mean age, 70 ± 10 years; gender, 26 men 15 women) percutaneous stents. Limb salvage indication for intervention 68% patients. Diabetes present 54%, 36% had end-stage renal Nitinol placed superficial (35 patients) (6 arteries. The mean postprocedural increase ankle-brachial index 0.32 0.19. 6-month, 1-year, 2-year primary patency limb-salvage rates 95%, 84%, 92%, 89%, respectively. Major amputations occurred only undergoing procedures presenting major tissue loss. No statistically significant differences seen regard to diabetes, disease, runoff score, length vessel stented (median, 80 mm), hypertension, smoking. Conclusions Our initial experience disease appears demonstrate acceptable at these early time points. Further evaluation devices this larger groups is warranted.
