Spontaneous Restoration of Patency in the Free Gastroepiploic Artery Graft: The Living Transplanted Vascular System for Coronary Revascularization

Comparison of saphenous vein graft versus right gastroepiploic artery to revascularize the right coronary artery: A prospective randomized clinical, functional, and angiographic midterm evaluation

“…An evaluation of graft patency or function based on clinical symptoms or angiographic controls driven by ischemic episodes could only provide a truncated vision of the actual revascularization status of the patients. 20 Several observations have demonstrated the capacity of internal thoracic arteries 21 or RGEAs 22 to recover a function at long term after having been found nonfunctional (string sign) at early follow-up. This capacity seems related to endothelial protection mechanisms that are probably absent in SVGs.…”
