To assess the clinical efficacy and application value of the Turbo Hawk atherectomy system in treating patients with superficial femoral artery stenosis or occlusion.

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.

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).

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.
