A marked tortuosity of the digital arteries ("ribbon" sign) at the site of a digit amputation is a sign of a severe avulsion injury to the neurovascular bundles. When this finding is present, the artery should be resected and the gap bridged by a vein graft, if revascularization is attempted.
手指离断部位的指动脉显著迂曲（“带状”征）是神经血管束严重撕脱伤的征象。若试图进行血管重建，出现此发现时，应切除动脉并用静脉移植物桥接缺口。
