Official Description

Obliteration of carotid aneurysm, arteriovenous malformation, or carotid-cavernous fistula by dissection within cavernous sinus

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 61613 involves the obliteration of a carotid aneurysm, arteriovenous malformation, or carotid-cavernous fistula through dissection within the cavernous sinus. This complex surgical intervention is performed to address issues related to the carotid artery, which is a major blood vessel supplying blood to the brain and face. The conditions treated by this procedure may include a carotid aneurysm, which is a bulging or ballooning in the artery wall that can lead to rupture; an arteriovenous malformation, which is an abnormal tangle of blood vessels connecting arteries and veins; or a carotid-cavernous fistula, which is an abnormal connection between the carotid artery and the cavernous sinus, a cavity at the base of the skull. The dissection within the cavernous sinus allows the physician to access and repair these vascular abnormalities, thereby preventing potential complications such as hemorrhage or neurological deficits. This procedure is critical for restoring normal blood flow and reducing the risk of serious health issues associated with these vascular conditions.

1. Indications

The procedure described by CPT® Code 61613 is indicated for specific vascular conditions affecting the carotid artery. These include:

  • Carotid Aneurysm A bulging or ballooning in the wall of the carotid artery that poses a risk of rupture and subsequent hemorrhage.
  • Arteriovenous Malformation An abnormal tangle of blood vessels that can disrupt normal blood flow and lead to complications such as bleeding or neurological issues.
  • Carotid-Cavernous Fistula An abnormal connection between the carotid artery and the cavernous sinus, which can result in increased pressure and potential damage to surrounding structures.

2. Procedure

The procedure for obliterating a carotid aneurysm, arteriovenous malformation, or carotid-cavernous fistula involves several critical steps:

  • Step 1: Anesthesia Administration The patient is placed under general anesthesia to ensure comfort and immobility during the procedure. This is essential for the safety and effectiveness of the surgical intervention.
  • Step 2: Surgical Access The surgeon makes an incision to access the cavernous sinus, which is located at the base of the skull. This step is crucial as it allows direct visualization and manipulation of the vascular structures involved.
  • Step 3: Dissection The surgeon carefully dissects through the surrounding tissues to reach the carotid artery and the affected area within the cavernous sinus. This step requires precision to avoid damaging adjacent nerves and blood vessels.
  • Step 4: Obliteration of the Affected Area Once access is achieved, the surgeon performs the necessary techniques to obliterate the aneurysm, arteriovenous malformation, or fistula. This may involve clipping, suturing, or other methods to ensure that the abnormality is effectively addressed.
  • Step 5: Closure After the obliteration is complete, the surgeon carefully closes the incision in layers, ensuring that the tissues are properly aligned and secured to promote healing.

3. Post-Procedure

Following the procedure, patients are typically monitored in a recovery area for any immediate complications. Post-procedure care may include pain management, monitoring for signs of infection, and neurological assessments to ensure that the patient is recovering appropriately. Patients may be advised to limit physical activity for a specified period to allow for proper healing. Follow-up appointments are essential to evaluate the success of the procedure and to monitor for any potential recurrence of the vascular condition.
