Creation of arteriovenous fistulas (AVF) for providing vascular access in patients dependent on hemodialysis is a very frequent type of surgery. One of the common complications of such a fistula is the formation of an aneurysm or a pseudoaneurysm and the risk of impending rupture. These are a few of the reasons why such surgically created AVF have to be taken down surgically. Some of these may be taken down for cosmetic reasons electively while some present in an emergency due to rupture of the aneurysm itself.
This is a retrospective study of 26 patients who underwent AVF takedown at our center over a period of 4 years.
We intended to study the patient profile, the surgery that they underwent and the post-operative course of these patients.
We found that aneurysm formation was the most common reason for a takedown, although we did see a good percentage of patients who presented to us with a ruptured AVF aneurysm. Our procedure was a ligation of the aneurysm with resection of the aneurysmal segment and maintaining arterial continuity. No attempt to preserve the fistula was made in any of these cases.
This article gives a brief overview of our experience in AVF takedown.
为依赖血液透析的患者建立动静脉内瘘（AVF）以提供血管通路是一种非常常见的手术类型。这种内瘘的常见并发症之一是动脉瘤或假性动脉瘤的形成以及即将破裂的风险。这些是必须通过手术拆除此类手术创建的AVF的一些原因。其中一些可能出于美容原因选择性地拆除，而一些则由于动脉瘤本身破裂而在紧急情况下出现。
这是一项对我们中心在4年期间接受AVF拆除手术的26例患者的回顾性研究。
我们旨在研究患者概况、他们接受的手术以及这些患者的术后病程。
我们发现动脉瘤形成是拆除手术最常见的原因，尽管我们确实看到相当比例的患者是因AVF动脉瘤破裂前来就诊。我们的手术方法是结扎动脉瘤并切除动脉瘤段，同时保持动脉连续性。在所有这些病例中均未尝试保留内瘘。
本文简要概述了我们在AVF拆除方面的经验。
