Short-segment saphenous vein interposition for left coronary artery reconstruction during redo valve-sparing root replacement resulted in preserved valve function and satisfactory coronary flow.
Case Report (n=1)
Short-segment saphenous vein interposition represents a practical bailout option for left coronary artery reconstruction during complex redo aortic root surgery when direct reimplantation is unsafe.
Abstract Redo aortic root surgery for acute type A aortic dissection is technically demanding, particularly when coronary reconstruction is complicated by tissue fragility. Reliable bailout strategies are required when direct coronary reimplantation is unsafe during valve-sparing root replacement. A 52-year-old man previously underwent total arch replacement with a frozen elephant trunk for acute type A aortic dissection. He later developed progressive aortic root dilatation and a proximal anastomotic pseudoaneurysm, and redo valve-sparing root replacement was performed. Intraoperatively, the left coronary artery was severely dissected and unsuitable for reimplantation. A short segment saphenous vein graft was interposed between the trimmed left main trunk and the neo-aortic root. Postoperative imaging confirmed preserved valve function and satisfactory coronary flow. Short-segment saphenous vein interposition represents a practical bailout option in complex redo aortic root surgery.
Kinoshita et al. (Tue,) conducted a case report in Redo type A aortic dissection (n=1). Valve-sparing root replacement with short saphenous vein interposition was evaluated on Valve function and coronary flow on postoperative imaging. Short-segment saphenous vein interposition for left coronary artery reconstruction during redo valve-sparing root replacement resulted in preserved valve function and satisfactory coronary flow.
