头静脉弓狭窄的研究进展

Research progress of cephalic arch stenosis

自体动静脉内瘘是维持性血液透析患者首选的永久性血管通路类型,狭窄是其主要并发症,可能导致发病率和死亡率增加。近年,我国肱动脉-头静脉内瘘逐年增多,头静脉弓狭窄是最常见的并发症。由于特殊的解剖结构及几何构型,在发病机制、临床表现、治疗等方面与其他部位狭窄有诸多不同。本文拟就近年头静脉弓狭窄研究进展作一综述。

Arteriovenous fistulas serve as the preferred permanent vascular access type for maintenance hemodialysis patients,stenosis is the main complication,which may lead to increased morbidity and mortality. In recent years,brachiocephalic fistulas are increasing year by year in China,cephalic arch stenosis( CAS) is the most common complication. Due to its special anatomical structure and geometric configuration, there are many differences in pathogenesis,clinical feature and treatment from stenosis in other parts. In this review we sunnarized research progress of CAS in recent years.
