经皮机械血栓旋切术在下肢血管疾病中的临床分析

The clinical analysises of percutaneous mechanical thrombectomy apply to vascular disease

近30年来，随着科学的进步和发展，血管腔内技术也得到了不断的完善和拓展，血运重建技术使血管阻塞性疾病的治疗有了飞跃的发展。介入治疗因其创伤小、可重复、安全性高、近期疗效显著等优点已逐渐代替了传统的开放治疗。外周血管腔内治疗手段包括经皮腔内血管成形术、支架置人术、导管溶栓术、经皮机械血栓旋切术等。经皮腔内血管成形术已成为大多数血管狭窄疾病的首选治疗，但其具有局限性，比如用于偏心性长段及严重钙化的动脉闭塞手术难度大、近期和远期通畅率低、术后并发症多；用于溃疡性斑块的治疗肢体远端栓塞的概率高；术后管腔的固有回缩力、血管内膜炎症反应、支架内血栓形成致使再狭窄等问题频发。然而经皮机械血栓旋切术是为解决上述临床问题而与工程技术良好结合所研发的新技术，本文旨在阐述现有经皮机械血栓旋切器械SilverHawk／TurboHawk和StraubRotarex的发展现状及其临床麻，崩疗效分析．

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 fi）rce for postoperative lumen, intimal inflammation restenosis, stent thrombosis cause problems frequently. However,the percntaneous mechanical thrombectomy system is aimed at solving the clinieal problems with good combination of engineering and technology research. The purpose of this paper is to expound the existing mechanical embolus removal system： SilverHawk/TurboHawk and Straub Rotarex thrombus.that is to elaborate its development status and clinical analysis.
