Radial artery occlusion leading to hand ischemia is a serious problem that may require prompt surgical intervention. Due to the rarity of these events, consensus on the most effective surgical approach has not yet been reached. There is even scarce literature on appropriate management of symptomatic radial occlusion in patients with a congenital variation in hand vasculature. We report on a case of a 38-year-old woman with radial artery occlusion who underwent a successful distal radial artery bypass to the deep palmar arch due to a diminutive ulnar artery and the absence of a superficial palmar arch. Radial artery bypass to the deep palmar arch using a reversed vein graft is a viable treatment option for preventing further digital ischemia or necrosis in patients with a compromised vasculature of the hand.
桡动脉闭塞导致手部缺血是一个严重问题，可能需要及时进行手术干预。由于这些事件罕见，尚未就最有效的手术方法达成共识。关于手部血管先天性变异患者有症状的桡动脉闭塞的适当管理，文献甚至也很匮乏。我们报告了一例38岁桡动脉闭塞的女性患者，因其尺动脉细小且掌浅弓缺如，成功接受了桡动脉远端至掌深弓的旁路移植术。对于手部血管受损的患者，使用静脉移植进行桡动脉至掌深弓的旁路移植是预防进一步手指缺血或坏死的可行治疗选择。
