CPT® Code 35103

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for ruptured aneurysm, abdominal aorta involving iliac vessels (common, hypogastric, external)

The CPT® Code 35103 refers to the surgical procedure for the direct repair of a ruptured abdominal aortic aneurysm or pseudoaneurysm, particularly when there is involvement of the iliac vessels, which include the common, hypogastric, and external iliac arteries. An abdominal aortic aneurysm is characterized by an abnormal enlargement or dilation of the abdominal aorta, which can lead to serious complications if not addressed promptly. The condition may arise from various factors, including arteriosclerosis, mechanical obstructions, or less common causes such as infections or vessel wall abnormalities. A pseudoaneurysm, in contrast, is a hematoma that forms outside the arterial wall and is typically the result of trauma or procedural complications, distinguishing it from a true aneurysm that involves all three layers of the artery wall. During the procedure, a surgical incision is made to access the abdominal aorta, allowing the surgeon to directly repair or excise the aneurysm and insert a graft, which may or may not include a patch graft. This intervention is critical in emergency situations where a ruptured aneurysm poses an immediate risk of significant blood loss. The surgical approach involves careful dissection and clamping of the aorta and iliac arteries to control bleeding, followed by the removal of any thrombus within the aneurysm sac and the placement of a synthetic graft to restore normal blood flow. The procedure is complex and requires meticulous attention to detail to ensure successful outcomes and minimize complications.
