Arteriovenous fistulas are a principal mainstay of long-term dialysis access for patients with end stage renal failure. However, the patency of arteriovenous fistulas is limited, often requiring percutaneous transluminal angioplasty as a salvage procedure. We report a case of percutaneous method of arteriovenous fistula salvage.
A gentleman with brachiocephalic arteriovenous fistula created in 2015 was admitted under us for dialysis access issue. His fistula history was notable for recurrent and refractory venous outflow stenosis of the cephalic vein and the cephalic arch with multiple previous interventions. Ultrasound showed cephalic arch occlusion with high venous pressures. He underwent left brachicephalic fistula percutaneous bypass. We describe the percutaneous creation of a brachial-subclavian arteriovenous fistula via a bypass graft from a worsening brachial-cephalic fistula with cephalic arch occlusion that is not amendable to angioplasty.
Final angiogram showed smooth flow to central vein. He is 2 years post procedure, and his fistula remained patent with no interventions required.
Percutaneously created jump bypass grafts can reliably produce sustained long-term patency.
动静脉瘘是终末期肾衰竭患者长期透析通路的主要支柱。然而,动静脉瘘的通畅性是有限的,通常需要经皮腔内血管成形术作为挽救措施。我们报告了一例经皮动静脉瘘挽救的病例。
一位 2015 年建立肱动脉动静脉瘘的男性因透析通路问题被收入我院。他的瘘管病史表现为头静脉和头臂静脉反复出现难治性静脉流出道狭窄,且多次介入治疗。超声显示头臂静脉弓闭塞伴静脉压升高。他接受了左肱动脉动静脉瘘经皮旁路手术。我们描述了一种通过从闭塞的头臂静脉弓的恶化肱动脉-头静脉瘘创建旁路移植来经皮创建肱-锁骨下动静脉瘘的方法,该旁路移植不适于血管成形术。
最终的血管造影显示中心静脉血流顺畅。他在手术后 2 年,瘘管保持通畅,无需进一步干预。
经皮创建的跳跃旁路移植物可以可靠地产生持久的长期通畅性。
