Mid and long term results of endovascular procedures for diabetic below-the-knee lesions / 中华普通外科杂志

ABSTRACT

Objective To analyze the mid and long term results of endovascular procedures for diabetic below-the-knee lesions.Methods We retrospectively analyzed data of 762 patients (797 limbs in Wagner Grade 1 to 4) who suffered ischemic symptoms of diabetic below-the-knee lesions,admitted for endovascular procedures from Aug 2005 to May 2012.Technical success rate and complications,anklebrachial index,wound healing,limb salvage and survival were evaluated.Results 762 patients (797 limbs) underwent 857 endovascular procedures with immediate technical success in 805 times (success rate 93.93％).30 day complications included 33 cases (4.33％) of hematoma or pseudoaneurysm related to access site,20 cases (2.62％) of vasovagal reflex,38 cases (4.99％) of belowthe-knee arteriorrhexis,75 cases (9.84％) of inflow-limited dissection,23 cases (3.02％) of arterial embolism,4 cases (0.52％) of blue-toe sign.Postoperative mean ABI was improved significantly,from 0.33 ± 0.20 to 0.68 ± 0.17,P ＜ 0.005.722 patients (751 limbs) were followed up for more than 12 months (35 ± 23 months),wound healing rate within 3 months was 72.28％,limb salvage rate after 12 months was 85.62％,survival rate was 95.01％.Conclusions Immediate technical success rate of endovascular procedures for diabetic below-the-knee lesions is high,complications rate is low,medium and long term efficacy is satisfactory.
