Bypass graft revision is a surgical procedure used to revise or replace a previously placed bypass graft that has become blocked, narrowed, or failed over time. Bypass grafts are commonly used in procedures such as coronary artery bypass grafting (CABG) or peripheral artery bypass. The revision procedure involves either replacing the old graft with a new one or using other techniques to restore blood flow through the affected area.

Bypass graft revision is crucial for ensuring continued circulation, preventing complications like tissue damage or amputation, and improving the patient's quality of life.
