Aortic Arch Graft Wrapping with Pedicled Omentum: Angiographic Assessment of the Omentum

Although the placing of a pedicle of omentum to wrap replaced aorta in an infected field is a well established procedure, there have been few reports that have demonstrated the postoperative vascular supply to such omental wraps. In our series of patients undergoing this procedure, postoperative selective angiography of the right gastroepiploic artery (RGEA) was performed in one case, and showed well developed vascularity of the omentum surrounding the replaced graft. This ample blood supply might explain the role played by omentum in the prevention of postoperative graft infection.
