Turbo Hawk斑块旋切系统治疗下肢动脉硬化闭塞症的疗效评估

Efficacy of Turbo Hawk atherectomy system in treatment of lower extremity arteriosclerosis obliterans

目的探讨Turbo Hawk斑块旋切系统治疗股浅动脉硬化狭窄或闭塞患者的临床疗效及应用价值。方法本研究回顾分析新疆维吾尔自治区人民医院2016年1月至2017年12月经下肢动脉成像确诊股浅动脉硬化闭塞或狭窄,且使用Turbo Hawk斑块旋切系统治疗的60例患者的临床资料,评估术后患者临床症状改善程度、管腔通畅度及血流动力学改善情况。采用t检验比较术前术后患者股浅动脉病变处管腔狭窄程度和踝肱指数(ABI)的差异。结果60病例符合Rutherford分类法3~6级的患者,术后临床症状明显改善的占46.67%(28/60),术后临床症状中度改善占53.33%(32/60)。术后数字减影心血管造影术(DSA)示管腔狭窄程度较术前明显下降[(0.26±0.05)分vs(0.90±0.08)分],差异具有统计学意义(t=2.847,P=0.015),术后ABI较术前明显升高(0.85±0.11 vs 0.25±0.13),差异具有统计学意义(t=1.546,P=0.023)。结论Turbo Hawk斑块切除术可以清除股浅动脉硬化闭塞斑块,开通狭窄或闭塞的动脉管腔,改善患者临床症状,是一种有效地腔内减容方案。

Objective To assess the clinical efficacy and application value of the Turbo Hawk atherectomy system in treating patients with superficial femoral artery stenosis or occlusion. Methods This study retrospectively analyzed the clinical data of 60 patients with superficial femoral arteriosclerosis occlusion or stenosis diagnosed by lower extremity artery imaging and treated with the TurboHawk plaque circumcision system at Xinjiang Uygur Autonomous Region People′s Hospital from January 2016 to December 2017. The clinical symptoms, lumen stenosis degree, and ankle brachial index (ABI) of patients with superficial femoral artery lesions before and after operation were observed to evaluate the improvement of clinical symptoms, lumen patency, and hemodynamics. Results Of the 60 patients who had grades 3-6 disease according to the Rutherford classification criteria, 46.67%(28/60) showed significant improvement in clinical symptoms after surgery, and 53.33%(32/60) showed moderate improvement in clinical symptoms Postoperative digital subtraction angiography (DSA) showed a significant decrease in lumen stenosis compared with preoperative value (0.26±0.05 vs 0.9±0.08, t=2.847, P=0.015). Postoperative ABI was significantly higher than preoperative value (0.85±0.11 vs 0.25±0.13, t=1.546, P=0.023). Conclusion Turbo Hawk plaque resection can remove the plaque of superficial femoral arteriosclerosis occlusion, open the narrowed or occluded arterial lumen, and improve the clinical symptoms, representing an effective intraluminal volume reduction method.
