Endovascular procedure for TASC-D type iliac artery lesions / 中华普通外科杂志

ABSTRACT

Objective To evaluate recanalization for TASC-D type iliac artery lesions.Methods Between June 2006 and June 2010,26 patients with a total of 31 limbs of the TASC-D iliac artery lesions underwent endovascular procedure. Results Technical success rate was 90.3% (28/31).Clinical symptom improvement rate was 100%. Forty-four stents were placed in 28 limbs of the 24 patients.Eleven patients underwent an associated procedure; femoropopliteal endovascular procedures in 8 cases,femoro-popliteal bypass in 3 cases. Eight patients underwent an intravascular ultrasound thrombolysis.Postoperative ankle-brachial index ( ABI) was increased by more than 0. 15 in all patients. Twenty-two patients(26 limbs) were followed-up for 3 -44 mos, the primary patency rate at 12 months was 90% ,and cumulative patency rate was 95%. At 36 months primary patency rate was 70% , and secondary patency rate was 80%. Conclusions Because the technical success rate is high, endovascular techeniques are the choice of therapy in high risk patients with TASC-D type iliac artery lesions.
