A Case of LMT Reconstruction Using Superficial Femoral Artery Graft in the Patient with Type A Acute Aortic Dissection.

A 76-year-old woman underwent a Bentall procedure for acute aortic dissection. A dissection involving half of the proximal portion of the left main coronary artery trunk was confirmed. The dissected site was resected, and a section of the superficial femoral artery was harvested and used as an interposition graft between conduit and the residual left main trunk. Two years after surgery, the graft remained well patent. If the coronary dissection involves only the left main artery trunk, the superficial femoral artery should be used as an artery graft for the anatomical reconstruction, potentially leading to better early and late outcomes.
