The clinical analysises of percutaneous mechanical thrombectomy apply to vascular disease / 国际外科学杂志

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.

Clinical application of a mechanical thrombectomy:Straub Rotarex System / 介入放射学杂志

Objective To evaluate the clinical application of a mechanical thrombectomy Straub Rotarex System in peripheral artery.Methods Nine cases,3 men and 6 woman,aged 36-85 years,were included in this study,with 5 of atherosclerosis,and 4 suffering from carcinogenic emboli.All patients were treated with Straub Rotarex System(Straub Rotarex System,patent pending,Straub medical,Wangs,Switzland) under subacute or acute occlusion of lower-limb arteries,including 4 popliteal arteries,3 femoral arteries and 2 iliac arteries,with only one complicated popliteal artery.The lengths of occluded segments were 5.0-13 cm. Results All the thrombi were removed through this intervention accompanied by further bolloon dilation for those greater than 50% stenosis post-operatively,and the arteries were undergone recanalization without any complications.Conclusions Thrombectomy by Straub Rotarex System is safe and effective for patients with peripheral artery occlusion.
