ABSTRACT
Objective: To assess the clinical value of excisional atherectomy with the Turbohawk atherectomy device in treatment of lower limb vascular disease. Methods: A retrospective case study method was adopted by using clinical follow-up data between July 2016 and October 2017 from The First Affiliated Hospital of Xi'an Jiaotong University. There were 15 cases of lower limb vascular disease treated with Turbohawk atherectomy device as the atherectomy group. And 15 cases were selected out 284 ones treated with conventional endovascular therapy during the same period as the control group. Clinical features such as age, gender, clinical symptoms, risk factors for arteriosclerosis, the site and length of lower arterial lesion were considered matched with those of the atherectomy group. Analysis was carried out by comparing stenting rate and remission rate in the two groups, and modification of ABI and vascular patency rate 3 and 6 months after treatment. Results: The stenting rate of atherectomy group was 6.7% (1/15), which was lower than that of the control group (86.7%, 13/15)(P0.05). The patency rate of atherectomy group 6 months after treatment was 93.3% (14/15), which was higher than that of control group 73.3% (11/15)(P<0.05). Conclusion: The use of Turbohawk atherectomy device for treatment of lower limb atherosclerosis disease is a safe and efficient method.
ABSTRACT
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.
ABSTRACT
PURPOSE: Directional atherectomy (DA) was introduced for the management of infrainguinal arterial stenosis or occlusive lesions. The procedure success rate in the DEFINITIVE LE study was determined using radiologic imaging. The aim of our study was to determine the usefulness of intraoperative ultrasonography (USG) during DA for evaluating the early results of this procedure. METHODS: Patients who underwent DA from January to December 2014 were reviewed retrospectively. Twenty lesions from 14 patients with femoral artery stenosis (>70% stenosis) with short segment occlusive lesions (<2 cm in length) were treated. Among 20 lesions, 3 were treated with the TurboHawk system with a protective device due to lesion calcification. The percentage of stenosis during and after DA was determined with USG. RESULTS: Median follow-up was 5.1 months, and the procedural success rate (<30% stenosis at the end of the procedure) was 100% on angiography, but only 30% on intraoperative USG. On USG, median residual stenosis was 40% (range, 28%–42%) at the end of DA, 40% (range, 30%–55%) at 1 month, 55% (range, 35%–85%) at 6 months, and 64% (range, 60%–100%) at 1 year. There was one dissection, but no cases of perforation, pseudoaneurysm, or thrombosis. Primary patency, which was defined as a peak systolic velocity ratio ≤3.5 with no reintervention at 6 months, was found in 18 lesions (90%), and 11 of 14 patients (78.6%) were free of ischemic symptoms such as claudication at 6 months. CONCLUSION: Our results demonstrated that DA with intraoperative USG is an effective treatment option for short segment occlusive lesions of the femoral artery.

For recently 30 years,with the progress of science,the development of intracavitary technology has been constantly improved and expanded.Reascularization technology makes the cure of vaso-occlusive disease a great leap.Because of its small trauma,repeatable,high security,near future curative effect,interventional therapy is distinctly superior to the traditional treatment such.Peripheral vascular lumen treatments including the balloon dilatation,stent-assisted angioplasty,catheter guided thrombolysis,and percutaneous mechanical thrombectomy,etc.Although angioplasty has become the best choice but the preferred treatment has limitations,such as for long and severe calcification of arteries occlusion surgery is difficult,immediate and long-term patency rate is low,the postoperative complications is frequent;Used for plaque ulcer and potentially thromboembolic disease,body highly risks of distal embolization;Inherent retraction force for postoperative lumen,intimal inflammation restenosis,stent thrombosis cause problems frequently.However,the percutaneous mechanical thrombectomy system is aimed at solving the clinical problems with good combination of engineering and technology research.The purpose of this paper is to expound the existing mechanical embolus removal system:SilverHawk/TurbjHawk aod Straub Rotarex thrombus,that is to elaborate its development status and clinical analysis.
