CPT® Code 35511

The CPT® Code 35511 refers to a surgical procedure known as a bypass graft, specifically a subclavian-subclavian bypass graft. This procedure is performed to create an alternative pathway for blood flow around a diseased or obstructed segment of the subclavian artery, which is a major artery supplying blood to the upper limb and parts of the head and neck. In this context, the term "subclavian-subclavian" indicates that the bypass is performed between the two subclavian arteries, typically to address issues in the proximal subclavian artery that may affect blood flow to the contralateral subclavian artery. During the procedure, an incision is made at the base of the neck, just above the clavicle, to access the first subclavian artery. A similar incision is made on the opposite side to expose the second subclavian artery. A vein graft, often harvested from the saphenous vein in the leg, is then used to create a new pathway for blood flow. The surgical steps involve careful dissection, clamping of the arteries, and suturing of the vein graft to ensure proper connection and functionality. The procedure is critical for restoring adequate blood circulation in cases where the subclavian artery is compromised due to disease or obstruction, thereby improving overall vascular health and function in the affected areas.
