The type of hemodialysis access and its preservation impact the quality of life and survival of patients undergoing hemodialysis. Vascular access complications are among the top causes of morbidity, hospitalization, and catheter use, with significant economic burden. Poor maturation and stenosis continue to be key impediments to upper arm arteriovenous fistula feasibility. Cephalic arch is a common location for vascular access dysfunction due to its distinctive anatomy, complex valves, and biochemical alterations attributable to renal failure. Understanding cephalic arch stenosis is critical due to its high prevalence and treatment failure. The appropriate management option is highly debatable and mostly dependent on patient characteristics and interventionist's preference. Current options include, percutaneous transluminal balloon angioplasty, stent grafts, bare metal stents, cutting balloon angioplasty, endovascular banding, and surgical procedures. This article discusses the etiologies of cephalic arch stenosis as well as currents trends in management including endovascular and surgical options.
血液透析通路的类型及其保护会影响接受血液透析患者的生活质量和生存。血管通路并发症是发病率、住院和导管使用的主要原因之一,具有显著的经济负担。上臂动静脉瘘的可行性仍然受到不良成熟和狭窄的限制。由于其独特的解剖结构、复杂的瓣膜以及与肾衰竭相关的生化改变,头臂动脉弓是血管通路功能障碍的常见部位。了解头臂动脉弓狭窄很重要,因为它的患病率高且治疗失败率高。适当的治疗选择存在很大争议,主要取决于患者的特征和介入医生的偏好。目前的选择包括经皮腔内血管成形术、支架移植、裸金属支架、切割球囊血管成形术、血管内带环和手术。本文讨论了头臂动脉弓狭窄的病因以及目前包括血管内和手术在内的治疗趋势。
