Objective To discuss the application of retrograde popliteal artery puncturing under X-ray guidance in the interventional therapy for superficial femoral artery occlusion. Methods Retrograde popliteal artery puncturing under X-ray guidance was carried out in nine patients with long-segment occlusion of superficial femoral artery as antegrade recanalization via femoral artery approach had failed in them. After retrograde route was successfully established, the balloon dilation and suhsequent stent placement for occluded vessel were performed. Results The technical success was obtained in all patients. The occluded superficial femoral arteries were reopened and the symptoms of intermittent claudication disappeared. No serious complications such as injuries of adjacent nerves or vessels occurred. The ankle-brachial index (ABI) increased from preoperative (0.38 ± 0.13) to postoperative (0.92 ± 0.11) with the difference being statistically significant (P ＜ 0.01). A follow-up period lasting for 2-16 months was conducted. Eleven months after the treatment, intermittent claudication recurred in one case, and CT angiography showed that the distal part of the stent was narrowed. The symptoms were improved after percutaneous transcatheter angioplasty was performed again. Conclusion Retrograde popliteal artery puncturing under X-ray guidance is an effective and safe technique for the treatment of superficial femoral artery long-segment occlusion with stent placement,especially for patients in whom antegrade recanalization via femoral artery approach fails.
