CPT® Code 35091

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for aneurysm, pseudoaneurysm, and associated occlusive disease, abdominal aorta involving visceral vessels (mesenteric, celiac, renal)

The procedure described by CPT® Code 35091 involves the surgical intervention for an abdominal aortic aneurysm or pseudoaneurysm that also affects the visceral vessels, specifically the mesenteric, celiac, and renal 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. The causes of such aneurysms may include arteriosclerosis, mechanical obstructions, or less common factors such as infections or vessel wall abnormalities. A pseudoaneurysm, on the other hand, is a hematoma that forms in communication with the artery wall but does not involve all three layers of the arterial wall, often resulting from trauma or procedural complications. The surgical approach for this procedure may involve direct repair or excision of the aneurysm, along with the insertion of a graft, which may be accompanied by a patch graft if necessary. This intervention is critical for restoring normal blood flow and preventing potential rupture, which can lead to life-threatening situations. The procedure is performed in a controlled, elective setting, ensuring that all necessary precautions and preparations are in place to manage the patient's condition effectively.
