下肢深静脉血栓(deep vein thrombosis,DVT)是常见的周围血管疾病。针对DVT的治疗方法主要有抗凝治疗和血栓清除治疗。血栓清除治疗包括手术取栓、系统溶栓和导管溶栓(catheter directed thrombolysis,CDT)等方法。抗凝治疗是治疗DVT的经典方法,但不能直接溶栓,所以常与血栓清除治疗相结合。血栓清除治疗中的手术取栓是最早采用的血栓清除方法,但存在手术相关风险;系统溶栓通过外周静脉予以纤溶药物可达到完全溶解血栓的效果,但由于需要大量纤溶药物而且疗程长,必然增加出血风险。CDT作为近年来新发展的血栓清除技术,可以弥补手术取栓和系统溶栓的不足,成为治疗急性DVT的一种重要方法。
Deep vein thrombosis (DVT) is a common peripheral vascular disease. The treatment of DVT mainly anticoagulant therapy and thrombectomy treatment. Thrombectomy treatments include surgical thrombectomy, systemic thrombolysis and catheter-directed thrombolysis (CDT). Anticoagulant therapy is the classic method of treatment of DVT, but not directly thrombolytic, it often combined with thrombectomy. Surgical thrombectomy in thrombectomy is the earliest thrombectomy method, but there is the risk of surgery; systemic thrombolysis can be achieved by fibrinolytic drugs in the peripheral vein to achieve complete thrombolytic effect, but because of the need for a large number of fibrinolytic drugs and long course of treatment , Will inevitably increase the risk of bleeding. As a newly developed thrombectomy technique in recent years, CDT can make up for the shortage of surgical thrombectomy and systemic thrombolysis and become an important method for the treatment of acute DVT.
