Rotarex血栓清除系统在下肢动脉栓塞中的应用

Application of Rotarex Thrombectomy System in Lower Limb Arterial Embolism

下肢动脉栓塞是血管外科常见疾病之一,多见于心源性或主动脉源性栓子脱落,引发下肢动脉栓塞并继发血栓形成,导致组织缺血或坏死。虽然开放手术在清除新鲜血栓方面效果显著,但对于陈旧性血栓则清除困难,且手术对血管内膜损伤较大,易导致血栓再发。经皮导管接触性溶栓对新鲜血栓清除效果较好,但陈旧性血栓清除困难,耗时较长且易发生远端栓塞事件。Rotarex血栓清除系统在急性和亚急性下肢动脉栓塞治疗中表现出良好的清除效果,且创伤较小,因此在临床应用日益广泛。本文将详述Rotarex血栓清除系统治疗下肢动脉栓塞的手术技巧及相关治疗经验。

Lower limb arterial embolism is one of the common diseases in vascular surgery,which is mostly caused by the shedding of embolus from heart or aorta,leading to lower limb arterial embolism and secondary thrombus formation,resulting in tissue ischemia or necrosis.Although open surgery has a significant effect in removing fresh thrombus,it is difficult to remove old thrombus,and the surgery causes great damage to the vascular intima,which is easy to lead to thrombus recurrence.Catheter-directed thrombolysis has a good effect on the removal of recent thrombus,but it is difficult to remove old thrombus,which takes a long time and is prone to distal embolism events.Rotarex thrombus removal system has shown good removal effect in the treatment of acute and subacute lower limb arterial embolism,with less trauma,so it is increasingly widely used in clinical practice.This article will elaborate on the surgical skills and related treatment experience of Rotarex thrombus removal system in the treatment of lower limb arterial embolism.
