持久，稳定的血管通路是维持尿毒症患者透析稳定性的先决条件。动静脉内瘘失功严重影响规律透析患者的生活质量。对于早期内瘘失功，可采用物理及溶栓的方式时内瘘再通，但对于内瘘闭塞时间较长的患者，则需采用介入及手术方法干预才能挽救内瘘。所以在内瘘闭塞早期采取干预，可极大提高内瘘复通率，且减轻患者的痛苦及经济负担。本文总结国内外动静脉内瘘失功后挽救的策略。

Durable and stable vascular access is the prerequisite for maintenance hemodialysis in uremic patients. Dysfunctioning of arteriovenous fistula affects the quality of life of hemodialysis patients. Physical or thrombolysis treatment can be used as a recanalization method for dysfunctioning fistula at early stage. Interventional or surgical measure has to be used for fistula occlusion for a longer period of time. Therefore, rescue management at the early stage of fistula occlusion increases the chance for recanalization of the fistula, and also alleviates the disease and financial burdens of the patients. This paper summarizes
the rescue strategies for dysfunctioning of arteriovenous internal fistula.
