Retrograde tibial approach for endovascular recanalization of popliteal and tibioperoneal artery occlusion / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVES</b>To describe a procedure of the retrograde approach for endovascular treatment of complex popliteal and/or infrapopliteal occlusions and to determine its safety and efficacy in minimizing failure rates.</p><p><b>METHODS</b>Between January 2010 and March 2012, 28 patients (16 male and 12 female patients) received retrograde tibial approach after failure of antegrade intervention. There were 3 patients with severe claudication (Rutherford category 3) and 25 patients with critical limb ischemia (Rutherford category 4 to 6). From this group, two techniques were employed. Twenty-four patients were treated via a retrograde transpedal access site and 4 patients via a transcollateral loop technique. The clinical and follow-up data of these patients were analyzed retrospectively.</p><p><b>RESULTS</b>The technique success rates were 92.8% (26/28). No major complications and 3 (10.7%) minor sequelaes were documented in this study. Twenty-three patients were followed up for 3 to 29 months, with a mean of (14 ± 9) months. Overall patency was 73.9% (17/23) and 47.8% (11/23) at 6 and 12 months. Overall survival and limb salvage was 95.7% (22/23), ulcer were healed in 9/10 patients.</p><p><b>CONCLUSION</b>The use of retrograde tibial or pedal approach seems feasible and safety in case of failure in antegrade revascularization of popliteal and/or infrapopliteal occlusions.</p>
