Figure 2. Facial appearance at the time of anastomosis. After creation of the AV anastomosis with venous outflow the flap exhibited good perfusion. Overlayed vessel schematic showing the flow of blood from the patient’s facial artery to the flap-side facial vein to provide retrograde perfusion to the flap (red-to-blue lines). Outflow of the flap runs through a separately identified facial vein to the patient-side facial vein (solid blue lines). Arrows denoting direction of blood flow. AV: Arteriovenous.
