CPT® Code 35634

The CPT® Code 35634 refers to a surgical procedure known as a bypass graft, specifically an iliorenal bypass graft using synthetic conduit rather than a vein. This procedure is performed to create a new pathway for blood flow around a diseased or obstructed segment of the renal artery, which is crucial for maintaining adequate blood supply to the kidneys. The iliorenal bypass involves the use of a synthetic graft, which is a man-made material designed to replace or support the function of blood vessels. The procedure typically requires careful dissection and exposure of the common iliac artery, followed by the placement of the graft in a manner that allows blood to flow from the iliac artery to the renal artery, effectively bypassing the obstructed area. This intervention is essential for patients who may be experiencing symptoms related to renal artery obstruction, such as hypertension or renal ischemia, and aims to restore normal blood circulation to the affected kidney.
