“…Another is the discovery of significant competitive flow. This study by Huh et al [1] is a unique report on the reopening of arterial grafts. Burning questions have occupied surgeons performing arterial grafting for years: Does a "string" arterial graft ever become useful?…”

Background We have observed reopening of the occluded “no‐touch” saphenous vein (NT SV) composite grafts on follow‐up angiograms in patients who underwent coronary artery bypass graftings (CABGs). Methods Between 2008 and 2018, 1283 patients received NT SV conduits without or with surrounding pedicle tissue as composite grafts based on the in situ left internal thoracic artery (ITA) for CABG and underwent early postoperative angiographies. Among the 1283 patients, 53 patients showed 55 occluded SV conduit anastomoses, and 46 patients who had 48 occluded SV anastomoses were re‐evaluated by 1‐year postoperative angiographies. Results Early postoperative angiographies in 1283 patients demonstrated overall occlusion rates of 1.2% (56/4518); occlusion rates of the ITA and SV were 0.08% (1/1259) and 1.7% (55/3260), respectively. One‐year angiograms demonstrated that 14 occluded SV anastomoses (29.2% [14/48 occluded SV]) of 14 patients became patent. Reopening of occluded SV conduits occurred more frequently in NT SV with pedicle tissue than in NT SV without pedicle tissue (45.0% [9/20] vs. 17.9% [5/28]; p = .057). When we examined the preoperative and 1‐year postoperative angiograms, reopening of the occluded SV conduits was not related with progression (p = .258) or preoperative reversibility score (p = .115) of native target coronary artery disease. Conclusions More than a quarter of the occluded SV composite grafts on early postoperative angiograms were patent in the 1‐year angiograms. The reopening rates were higher in patients who had received NT SV conduits with pedicle tissue than those who had received NT SV conduits without pedicle tissue.

Spasm and Reopening of the Right Gastroepiploic Artery Conduit After Coronary Artery Bypass Grafting

Abstract: Reopening of occluded RGEA conduits occurred early and midterm postoperatively. Reopening appeared related to recovery from graft spasm, and could occur as late as midterm if associated with progression of native coronary artery disease.
