The optimal percutaneous coronary intervention method for treating distal anastomotic lesions in bypass grafts remains controversial, despite its use as an alternative to high-risk redo surgery.
This review summarizes the incidence, pathogenesis, and treatment approaches for distal anastomotic lesions in venous and arterial bypass grafts.
Optimal PCI for distal anastomotic lesions remains controversial; leaves open the preferred approach pending prospective comparative trials.
Distal anastomotic lesions are the most common reason for venous and arterial graft failure. Redo coronary artery bypass surgery carries a higher risk for mortality and non-fatal myocardial infarction. Many operators therefore consider percutaneous coronary intervention as a good alternative for relieving angina symptoms in this subset of patients with anastomotic lesions. However, the best percutaneous method for treating these lesions is still controversial. Here we review reported data on the incidence, pathogenesis, and treatment of distal anastomotic lesions in both venous and arterial bypass grafts.

Badr et al. (2012) conducted a review in Distal anastomotic lesions after coronary artery bypass surgery. Percutaneous coronary intervention was evaluated. The optimal percutaneous coronary intervention method for treating distal anastomotic lesions in bypass grafts remains controversial, despite its use as an alternative to high-risk redo surgery.
