For the over 400,000 patients in the United States dependent on hemodialysis, arteriovenous (AV) access thrombosis may lead to missed dialysis sessions, inpatient admissions and the need for placement of temporary dialysis catheters. It is also the leading cause of permanent access loss. Percutaneous declotting is generally preferred over surgical thrombectomy. Various percutaneous approaches can be employed including the lyse-and-wait technique, thromboaspiration, pulse spray aided pharmacomechanical thrombolysis, and use of mechanical thrombectomy device.
在美国,超过40万依赖血液透析的患者中,动静脉(AV)通路血栓形成可能导致透析疗程错过、住院治疗以及需要放置临时透析导管。它也是永久性通路丧失的主要原因。经皮清除血栓通常比外科血栓切除术更受青睐。可以采用多种经皮方法,包括溶解等待技术、血栓抽吸、脉冲喷射辅助药物机械溶栓以及使用机械血栓清除装置。
