Aneurysmal arterial dilatation is an infrequent complication following arteriovenous fistula ligation. Herein, we are describing a case in which a 49-year-old transplanted patient developed a true, symptomatic, brachial artery aneurysm 25 years after transplantation and 12 years after ligation of his radiocephalic wrist fistula. Treating strategy included aneurysmectomy and reversed vein interposition using ipsilateral, dilated branch of cephalic vein. Two years postoperatively, the patient remains without complications. Moreover, we mention the pathophysiologic mechanisms that may have contributed to this phenomenon.
动脉瘤样动脉扩张是动静脉瘘结扎术后罕见的并发症。在此，我们描述了一例49岁的移植患者，在移植25年后、桡动脉-头静脉腕部瘘结扎12年后发生了真性、有症状的肱动脉动脉瘤。治疗策略包括动脉瘤切除术和使用同侧扩张的头静脉分支进行静脉移植。术后两年，患者未出现并发症。此外，我们提到了可能导致这种现象的病理生理机制。
