case_images: Photographs of dog 1, showing (A) the soft tissue sarcoma preoperatively, (B) the delineation of the superficial brachial artery using the IC-Flow  camera system intraoperatively, and (C) flap edema at day 20 postoperatively.

case_images: The near infrared camera was turned on, and within 65 s after injection of the ICG-dye, the superficial brachial artery was fully visible (Figure 1B). Seroma formation was observed at first re-check and treated with warm packing three times daily until regression (Figure 1C).

case_images: Photographs of dog 2, showing (A) the dehiscent wound on the left medio-proximal antebrachium at presentation, (B) the delineation of the superficial brachial artery using the VisionSense VS3-IR-MMS camera system intraoperatively, and (C) the discoloration of the distal edges of the flap on day 6 postoperatively.

case_images: It was then transferred for wound management and further treatment of the incompletely resected mast cell tumor (Figure 2A). The VisionSense VS3-IR-MMS  camera system was operated in angiography setting (30-cm working distance, 90  angle) and used to map the course of the superficial brachial artery (Figure 2B). Three and 6 days postoperatively, the flap showed no sign of edema or seroma; however, the craniodistal and caudodistal borders showed dark red discoloration but had no signs of induration or temperature differences compared to the surrounding tissues (Figure 2C).

case_images: The left superficial cervical lymph node was identified transcutaneously as the draining lymph node (Figure 3A). A 2 cm incision was made directly overlying the NIR signal of the node, and the node was excised after separation of the muscle fibers of the brachiocephalic muscle (Figure 3B).
