This case report describes the method and feasibility of near-infrared angiography (NIRA) to improve the surgical procedure of two superficial brachial axial pattern flaps intraoperatively using two camera systems. Two client-owned dogs were treated for tumors on their antebrachia with wide surgical excision. The defects were closed with a superficial brachial flap in both cases. A different NIRA camera system was used for each case to identify the perforator vessel and flap margins accordingly. Case 1 developed a seroma and healed without further complications. Case 2 developed partial flap necrosis, underwent revision surgery, and healed by secondary intent. NIRA proved useful intraoperatively in identifying the perforator vessel and determining flap margins. As these are only two cases, caution should be used in extrapolating the results.
本病例报告描述了使用两个摄像系统在术中通过近红外血管造影（NIRA）改善两个臂浅轴型皮瓣手术操作的方法及可行性。两只客户拥有的犬因前臂肿瘤接受了广泛手术切除。两例均用臂浅皮瓣关闭缺损。每例使用不同的NIRA摄像系统来相应地识别穿支血管和皮瓣边缘。病例1出现了血清肿，愈合过程无进一步并发症。病例2出现了部分皮瓣坏死，接受了修复手术，并通过二期愈合。NIRA在术中被证明有助于识别穿支血管和确定皮瓣边缘。由于仅为两例，外推结果时应谨慎。
