Arterial repair in upper extremity BT has excellent early and long-term outcome. In contrast to a significant risk of early occlusion, limb loss after repair, late vascular re-intervention and late arterial occlusion or stenosis are rare.
Emergency repair of civilian artery injuries with the use of vein grafts is associated with considerable risk of early occlusion and limb loss. When compared with the upper limb, limb loss rate is significantly higher in the lower extremity. Early graft occlusion is frequently followed by limb loss, especially in the lower limb. During long-term follow-up, occlusions of interposed vein grafts, vascular reinterventions, and late amputations are uncommon.
Abnormal cold intolerance is frequently seen in patients with a history of arterial repair in upper limb trauma. It is associated with significant functional impairment. Concomitant nerve injury and involvement of the subclavian or axillary artery are the major predisposing factors for development of cold intolerance after upper limb trauma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
