Official Description

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for ruptured aneurysm, splenic artery

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 35112 involves the direct surgical repair of a ruptured splenic artery aneurysm or pseudoaneurysm, which may also include the excision of the affected area and the insertion of a graft, with or without the use of a patch graft. An aneurysm is characterized by an abnormal enlargement or dilation of an artery, which can occur due to various factors such as arteriosclerosis, mechanical obstruction, or malposition of the artery. Less frequently, aneurysms may arise from conditions like syphilis, tuberculosis, or abnormalities in the vessel wall, such as fibromuscular dysplasia. In contrast, a pseudoaneurysm is defined as a hematoma that forms in direct communication with the artery wall but does not involve all three layers of the arterial wall, distinguishing it from a true aneurysm. Pseudoaneurysms often result from trauma—either blunt or penetrating—or as a complication from medical procedures, such as catheterization. Specific causes of splenic artery pseudoaneurysms can include pancreatitis, septic emboli, or arteritis. The splenic artery itself originates from the celiac trunk, which branches off from the abdominal aorta just below the diaphragm. The surgical approach for this procedure typically involves harvesting a saphenous vein graft from the lower leg if needed, followed by a midline abdominal, transverse, or retroperitoneal flank incision to access the splenic artery. The procedure is critical in emergency situations where a ruptured aneurysm poses a significant risk of hemorrhage, necessitating immediate intervention to control bleeding and repair the artery.

1. Indications

The procedure described by CPT® Code 35112 is indicated for the surgical repair of a ruptured splenic artery aneurysm or pseudoaneurysm. The following conditions may warrant this procedure:

  • Ruptured Aneurysm A splenic artery aneurysm that has ruptured, leading to internal bleeding and requiring immediate surgical intervention.
  • Pseudoaneurysm A pseudoaneurysm of the splenic artery that may result from trauma or complications from medical procedures, necessitating repair to prevent further complications.
  • Associated Occlusive Disease Any occlusive disease associated with the splenic artery that may complicate the aneurysm or pseudoaneurysm, requiring surgical correction.

2. Procedure

The surgical procedure for CPT® Code 35112 involves several critical steps to ensure the successful repair of the ruptured splenic artery aneurysm or pseudoaneurysm:

  • Preparation and Incision The procedure begins with the preparation of the patient, including the harvesting of a saphenous vein graft from the lower leg if necessary. A midline abdominal, transverse, or retroperitoneal flank incision is then made to access the splenic artery.
  • Accessing the Aorta Once the incision is made, the overlying soft tissues are carefully divided to expose the duodenum, which is then dissected off the aorta. This allows for direct access to the aorta, where proximal control is established above the level of the celiac arteries and distal control above the iliac arteries.
  • Establishing Aortic Control Supraceliac aortic control is achieved by dividing ligaments attached to the left lateral segment of the liver and retracting this portion of the liver. The fibromuscular bands (crura) of the diaphragm are separated to facilitate the mobilization of the aorta.
  • Clamping and Repairing the Aneurysm After administering anticoagulants, the iliac arteries and proximal aorta are clamped to control blood flow. The aneurysm sac in the splenic artery is then opened longitudinally, and any thrombus is removed. The splenic artery is repaired using either an autogenous (saphenous vein) or synthetic patch or tube graft. If a tube graft is utilized, the aneurysm sac is closed over the graft.
  • Restoring Blood Flow Once the repair is complete, the clamps are released to restore blood flow to the area. The retroperitoneum is then repaired, and the abdominal incision is closed.

3. Post-Procedure

Post-procedure care following the surgical repair of a ruptured splenic artery aneurysm or pseudoaneurysm includes monitoring for any signs of complications, such as bleeding or infection. Patients may require hospitalization for observation and management of their recovery. The expected recovery period will vary based on the individual patient's condition and the extent of the surgery performed. Follow-up appointments will be necessary to assess the healing process and ensure that the repair is functioning as intended. Additionally, patients may need to adhere to specific activity restrictions during their recovery to promote healing and prevent complications.
