Clinical efficacy and outcome of endovascular therapy for complex arteriosclerosis obliterans of the lower extremities / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate efficacy and outcome of endovascular therapy for complex arteriosclerosis obliterans of the lower extremities.</p><p><b>METHODS</b>In this single-center retrospective study, the clinical data of consecutive 114 cases with TASC II type C/D lower extremity obstructive disease and clinical stage of Fontaine ≥ IIb and ankle brachial index <0.9 underwent endovascular therapy from December 2011 to January 2013 were collected. Telephone or clinic interviews were conducted to investigate the clinical outcomes.</p><p><b>RESULTS</b>There were 39 TASC II type C patients and 75 TASC II type D patients, 78 patients were in Fontaine IIb, 30 patients in Fontaine III and 6 patients in Fontaine IV stages. Immediate procedural success rate was 94.9% (131/138). Ankle brachial index was increased from 0.54 ± 0.26 at baseline to 0.83 ± 0.30 at discharge (P < 0.01). No adverse event was observed during the perioperative period. During (15.7 ± 8.7) months follow-up, cumulative patency rate of 6, 12 and 18 months was 75.8% (94/124) , 68.7% (68/99) and 39.2% (20/51) respectively and limb salvage rate was 100%.</p><p><b>CONCLUSION</b>Endovascular therapy for complex arteriosclerosis obliterans of the lower extremities is effective and safe.</p>
