TurboHawk plaque excision system combined with drug-coated balloon for the treatment of femoral popliteal artery in-stent restenosis / 中华普通外科杂志

ABSTRACT

Objective:To observe the clinical effect of TurboHawk plaque excision system combined with drug-coated balloon in the treatment of femoral popliteal artery in-stent restenosis.Methods:The clinical and follow-up data of 13 patients with femoral popliteal artery in-stent restenosis were retrospectively analyzed, ankle-brachial index (ABI) and lower extremity artery CTA before and after surgery were recorded.Results:Surgery was successful in all the 13 patients.There was perioperative death, no major complications. One patient underwent salvage stent implantation due to residual stenosis of more than 30% in the proximal end of the stent after rotary cutting and expansion . The average postoperative ABI was (0.90±0.08), significantly higher than that before the operation ( P<0.05). All patients were followed-up for mean 16.4 months, One patient died of acute heart failure after 13 months, one of the lower extremity vascular CTA confirmed in-stent restenosis was treated by drug-coated balloon. The primary patency rate was 84.6% at one year. Conclusion:The mid-term results of directional atherectomy system combined with drug-coated balloon in the treatment of femoral artery in-stent restenosis is satisfactory.
