Endovascular treatment for critical limb ischemia in patients with TASC C/D femoropopliteal lesions / 中华普通外科杂志

ABSTRACT

Objectives To assess outcomes of endovascular treatment for critical limb ischemia in patients with TASC C and D femoropopliteal lesions.Methods Between January 2009 and January 2012,patients with critical limb ischemia for TASC Ⅱ C or D lesions underwent endovascular treatment.Patients demographic,pre-and post- procedure ABI,primary patency rate,limb salvage at 1,3,6,12,24 months were reviewed.Results There were 58 males,38 females, mean age was (76 ± 10 ) years,with Rutherford Ⅳ in 68 limbs,Ⅴ in 23 limbs,Ⅵ in 5 limbs.Successful rate of procedure for target lesions was 94.80％,angioplasty alone was performed in 13 limbs,stent in 80 patients,thromblysis assisted angioplasty and stent in 8 limbs.Stents of popliteal artery were implanted in 47 limbs.Major complication rate was 19.80％,two patients died within 30 days.Mean ABIs were 0.25 ±0.17 and 0.76 ±0.23 before and after procedure.Mean time of follow up was (12 ± 6) months.Primary patency rates and limbs salvage rate were 94.79％ and 95.83％,93.73％ and 95.83％,88.01％ and 93.42％,78.34％ and 93.42％,68.38％ and 83.04％ on 1,3,6,12,24 months respectively.Conclusions Patients with critical limb ischemia caused by TASC C/D lesions often suffer from significant comorbid medical conditions.Endovascular procedure has a high risk of morbidity and restenosis,but short term limb salvage rate is satisfactory.
