RESUMO
Objective To evaluate the efficacy and safety of TurboHawk plaque resection system in the treatment of lower extremity arteriosclerosis obliterans.Methods Clinical data of 36 patients with atherosclerotic occlusion of lower extremity treated with TurboHawk from January 2016 to August 2017 were retrospectively collected.The characteristics of lesion,improvement of symptoms,ankle brachial index (ABI) and postoperative complications were analyzed.The measurement data were expressed as ((x) ± s),All patients were reviewed every 3 months after operation,followed up for 3-18 months,with an average of (9 ± 0.5) months.And the ABI comparison before and after treatment were performed by paired t test;the counting data were expressed as rate (％),and the comparison of different stages was performed by chi-square test.Results In 36 patients,the technical success rate was 100％,and the symptoms of lower limbs were significantly improved.The ABI (0.85 ±0.07) and ABI (0.75 ±0.10) were significantly better in 3 days and in 3 months after operation than before operation (0.29 ±0.10)(t =37.76,P ＜0.001).Postoperative complications occurred in 2 cases,in one case,the artery dissection was covered with a bare scaffold,and in the other case,the blood vessel was ruptured after resection,and was closured by using balloon angioplasty.Conclusion TurboHawk plaque resection system is an effective,less traumatic and safer option for the treatment of lower extremity arteriosclerosis obliterans.
