The procedure described by CPT® Code 61705 involves the surgical intervention for conditions such as an intracranial aneurysm, vascular malformation, or carotid-cavernous fistula. An intracranial aneurysm is characterized by a weakened area in the wall of a blood vessel within the brain that can expand and fill with blood, potentially leading to pressure on adjacent brain structures, pain, and neurological deficits. In severe cases, these aneurysms may rupture, resulting in a life-threatening intracranial hemorrhage. Vascular malformations encompass a range of abnormalities in blood vessel formation and function, which can lead to various complications depending on their nature and location. A carotid-cavernous fistula represents an abnormal connection between the carotid artery and the cavernous sinus, a venous structure located behind the eyes, which can disrupt normal blood flow and lead to significant clinical symptoms. The surgical approach for this procedure combines both intracranial and cervical techniques to effectively interrupt blood flow to the affected area. This is achieved by clamping the internal or external carotid artery, thereby reducing the risk of complications associated with these vascular conditions. The procedure requires careful dissection and manipulation of the carotid artery and surrounding tissues, utilizing microsurgical techniques to ensure precision and minimize damage to adjacent structures.

The procedure described by CPT® Code 61705 is indicated for the following conditions:
The surgical procedure for CPT® Code 61705 involves several critical steps to ensure effective treatment of the targeted vascular condition.
Post-procedure care following CPT® Code 61705 involves monitoring the patient for any signs of complications, such as neurological deficits or signs of infection. Patients may require imaging studies to assess the success of the occlusion and to ensure that there are no residual vascular issues. Recovery may vary depending on the individual patient's condition and the extent of the surgery performed. Follow-up appointments are essential to evaluate the patient's progress and to manage any potential complications that may arise during the recovery period.
