Extraanatomic bypass surgery

The term "extraanatomic bypass" applies to grafts that pass through a different anatomic pathway than do the natural blood vessels they replace. These grafts are devised to circumvent complex problems when conventional vascular procedures are not possible or are too hazardous to perform. There are various indications, advantages, and disadvantages to each of these grafts. Extraanatomic bypass grafts are an accepted technique with known patency rates. Quality nursing care plays a significant role in successful patient outcome.
