CPT® Code 35111

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, splenic artery

The procedure described by CPT® Code 35111 involves the surgical intervention for the repair of a splenic artery aneurysm or pseudoaneurysm, which may also include associated occlusive disease. An aneurysm is characterized by an abnormal enlargement or dilation of an artery, which can arise from various causes such as arteriosclerosis, mechanical obstruction, or malposition of the artery. Less frequently, conditions like syphilis, tuberculosis, or fibromuscular dysplasia may contribute to the formation of an aneurysm. In contrast, a pseudoaneurysm is a hematoma that forms in communication with the artery wall but does not involve all three layers of the arterial wall, typically resulting from trauma or complications from medical procedures. The splenic artery, which is the focus of this procedure, originates from the celiac trunk and is responsible for supplying blood to the spleen. Surgical repair may involve direct repair or excision of the aneurysm, along with the insertion of a graft, which can be either autogenous, such as a saphenous vein graft, or synthetic. This procedure is performed in a nonemergent, elective setting, distinguishing it from similar procedures that may be conducted in emergency situations, such as the repair of a ruptured splenic aneurysm.
