Fig 2.

Candidate for full face transplantation. A, After catastrophic loss of facial tissues, muscle flaps and skin grafts placed during >20 surgeries rendered the patient's face featureless. B, Surgical-planning volume-rendered CT angiography depicts residual arteries after previous reconstructions using bilateral free latissimus muscle and serratus muscle flap arteries (dashed arrows), which are anastomosed end-to-end to the bilateral facial artery stumps (arrows). While not ideal, those facial and/or flap arteries are technically available and considered for microsurgical anastomoses. Prior surgical clips are rendered in green using the multiobject segmentation described in the text. C, Venous images from the same CT acquisition show occluded or absent bilateral anterior, posterior facial, and left external jugular veins. Patency of the right external jugular vein (arrow) and bilateral internal jugular veins (dashed arrows) is confirmed.
