Arteriovenous access can result in complications including extremity ischemia and swelling. Use of the nondominant upper extremity is preferred because complications will result in less severe disability. The distal axillary vein in the axilla is usually considered to be the end point for arteriovenous access in the upper extremity. Vascular surgeons are familiar with exposure of the proximal axillary artery via an infraclavicular incision. The axillary vein is also easily exposed through this technique. Use of this vein for arteriovenous graft outflow can preserve the dominant arm for future use. Nine patients with arteriovenous grafts with venous outflow in the proximal arm for future use. All patients had exposure to the proximal axillary vein via an infraclavicular incision. There were six women and three men. All patients had multiple failed access in the ipsilateral extremity. One patient had a loop configuration graft, while the six others had a straight graft with arterial inflow via the brachial artery. One patient had a bovine mesenteric vein graft, while the remaining six had expanded polytetrafluoroethylene grafts. Six of the seven patients had ambulatory surgery, while one patient was admitted postoperatively with mental status changes. Patency rates were 78%, with mean follow-up of 16 months. One patient had early failure due to steal and one patient failed at 22 months. Six of seven patients are alive at current follow-up. Three patients required secondary procedures including venous angioplasty (n=2) and subclavian artery stenting (n=1). The infraclavicular axillary vein can be used as an effective outflow for arteriovenous grafts. This procedure can be done as an outpatient surgery with a low complication rate. This procedure can preserve the dominant arm for future access and provides a possible alternative to surgery on another extremity.
动静脉通路可能导致包括肢体缺血和肿胀在内的并发症。首选使用非优势上肢,因为并发症导致的残疾程度较轻。腋窝处的腋静脉远端通常被认为是上肢动静脉通路的终点。血管外科医生熟悉通过锁骨下切口暴露腋动脉近端。通过该技术也很容易暴露腋静脉。将此静脉用于动静脉移植物流出可保留优势手臂以备将来使用。9例患者的动静脉移植物的静脉流出位于近端手臂以备将来使用。所有患者均通过锁骨下切口暴露腋静脉近端。其中有6名女性和3名男性。所有患者同侧肢体的通路均多次失败。1例患者的移植物为袢状结构,其余6例为直形移植物,动脉流入通过肱动脉。1例患者使用牛肠系膜静脉移植物,其余6例使用膨体聚四氟乙烯移植物。7例患者中有6例行门诊手术,1例患者术后因精神状态改变入院。通畅率为78%,平均随访16个月。1例患者因窃血早期失败,1例患者在22个月时失败。7例患者中有6例在目前随访时存活。3例患者需要二次手术,包括静脉血管成形术(n = 2)和锁骨下动脉支架置入术(n = 1)。锁骨下腋静脉可作为动静脉移植物的有效流出道。该手术可作为门诊手术进行,并发症发生率低。该手术可保留优势手臂以备将来通路使用,并为另一个肢体的手术提供了一种可能的替代方案。
