The VasQ device was designed to improve the outcome of arteriovenous fistulae by optimizing the hemodynamics of the flow in the juxta-anastomotic region of the arteriovenous fistulae through tailored external support. The aim of the study was to evaluate the impact of the VasQ on outcome of radiocephalic arteriovenous fistulae in a real-world setting.
This was a single-center, retrospective analysis of patients with either fistula creation before or after dialysis initiation with implantation of the VasQ device during creation of end-to-side radiocephalic arteriovenous fistulae between June 2018 and May 2019. The flow rate and vein diameter were evaluated intraoperatively, at discharge within 48 h postprocedure and at a follow-up of 1, 3, 6, 9, and 12 months.
Thirty-three VasQ devices were implanted during 33 radiocephalic arteriovenous fistula procedures. The study population comprised mostly of men, with an average age of 66 years. Mean intraoperative flow was 428 mL/min (range: 130-945). All patients were discharged with patent arteriovenous fistulae and mean fistula flow of 740 mL/min (range: 230-1300 mL/min). The primary patency was 100% and 79% at 3 and 6 months, respectively. Cumulative/secondary patency was 100% and 90% at 3 and 6 months, respectively.
Data presented here suggest that the VasQ device has the potential to provide benefit to the functionality of radiocephalic arteriovenous fistulae.
VasQ 装置旨在通过对动静脉吻合口近吻合区域的血流进行定制化的外部支撑，优化血流动力学，从而改善动静脉瘘的结果。本研究的目的是评估 VasQ 在真实环境中对桡动脉-头静脉动静脉瘘结果的影响。
这是一项单中心、回顾性分析，纳入 2018 年 6 月至 2019 年 5 月期间在建立端端桡动脉-头静脉动静脉瘘时植入 VasQ 装置的患者，这些患者要么在透析开始前，要么在透析开始后创建瘘管。术中、术后 48 小时内出院时以及术后 1、3、6、9 和 12 个月时评估流量和静脉直径。
33 例桡动脉-头静脉动静脉瘘手术中植入了 33 个 VasQ 装置。研究人群主要为男性，平均年龄为 66 岁。平均术中流量为 428mL/min（范围：130-945）。所有患者均出院时瘘管通畅，瘘管平均流量为 740mL/min（范围：230-1300 mL/min）。3 个月和 6 个月时的一期通畅率分别为 100%和 79%。累积/二期通畅率分别为 100%和 90%。
这里提供的数据表明，VasQ 装置有可能为桡动脉-头静脉动静脉瘘的功能提供益处。
