Entrapment of the brachial artery within a compound dislocated elbow joint seems not to have been reported previously. Brachial artery rupture is the usual vascular injury associated with a compound elbow dislocation. A review of the surgical literature suggests that wide spectrum of disability may follow interruption of brachial artery flow at the elbow. While most patients experience no immediate or late ischemic symptoms because of the rich collateral network about the elbow, intermittent claudication or gangrene of the hand is possible and has been well-documented in the literature. To assure adequate circulation to the hand and prevent potential complications, reanastomosis or venous graft replacement of the damaged arterial segment is recommended at the time of traumatic disruption of the brachial artery.
肱动脉被困于复合性肘关节脱位内的情况此前似乎未见报道。肱动脉破裂是复合性肘关节脱位常见的血管损伤。外科文献回顾表明,肘部肱动脉血流中断后可能会出现广泛的功能障碍。虽然大多数患者因肘部丰富的侧支循环网络而未出现即刻或晚期缺血症状,但手部间歇性跛行或坏疽是有可能的,且文献中有充分记载。为确保手部有足够的血液循环并预防潜在并发症,在肱动脉发生创伤性断裂时,建议对受损动脉段进行重新吻合或静脉移植置换。
