CPT® Code 35633

The CPT® Code 35633 refers to a surgical procedure known as a bypass graft, specifically an ilio-mesenteric bypass graft using synthetic conduit rather than a vein. This procedure is performed to circumvent a diseased or obstructed segment of the superior mesenteric artery, which is crucial for supplying blood to the intestines and other abdominal organs. The ilio-mesenteric bypass graft aims to restore adequate blood flow to vital structures such as the liver, stomach, esophagus, spleen, and pancreas. During the procedure, the common iliac artery is accessed, and a synthetic graft is meticulously placed to create a new pathway for blood flow, effectively bypassing the affected area. This intervention is essential for patients experiencing significant vascular obstruction that could lead to ischemia or other serious complications. The use of synthetic materials in the graft allows for a durable and effective solution to restore circulation in cases where vein grafts are not feasible.
