Effect analysis of the technique of retrograde puncture of popliteal artery applied in the interventional therapy of lower extremity arteriosclerosis obliterans patients

Abstract

To investigate the effectiveness of retrograde puncture of popliteal artery in lower extremity arteriosclerosis obliterans(ASO) patients classified as TASC(Tans-Atlantic Inter-Society Consensus)C/D. Retrospective analysis of 35 lower extremity ASO patients, 28 male and 7 female , the mean age was 72±8, 23 cases of Rutherford 3, 8 cases of Rutherford 4 and 4 cases of Rutherford 5. Preoperative ABI was 0.35±0.14, Lesion length in CT angiography (CTA) was (18±5) cm. The technique success rate of 35 cases was 100%. The puncture time was (6±4) min.6 cases used 4 F sheath and 29 cases used no sheath technology at the puncture site. In 27 cases guide wires passed retrograde through the occluded superficial femoral artery lesion and returned to the true lumen.8 cases of SAFARI technology to established the guild wire track. The complication rate of retrograde puncture was 14.2%(5/35), 2 cases of postoperative hematoma appeared at the puncture site the next day, 2 cases of pseudoaneurysms emerged and 1 case of postoperative arteriovenous fistula at the puncture site of popliteal area were found by Doppler ultrasonography before discharged. All 5 patients were recovered by conservative treatment. The retrograde puncture of popliteal artery is a safe and reliable method. Key words: Arteriosclerosis; Popliteal artery; Punctures
