CPT® Code 61710

Surgery of aneurysm, vascular malformation or carotid-cavernous fistula; by intra-arterial embolization, injection procedure, or balloon catheter

The CPT® Code 61710 refers to a surgical procedure aimed at addressing conditions such as intracranial aneurysms, vascular malformations, or carotid-cavernous fistulas through intra-arterial embolization, injection procedures, or the use of balloon catheters. An intracranial aneurysm, also known as a cerebral or intracerebral aneurysm, is characterized by a weakened segment of a blood vessel that bulges and fills with blood. This condition can exert pressure on adjacent brain structures, potentially leading to pain and neurological deficits. Furthermore, there is a risk of rupture, which can result in a life-threatening intracranial hemorrhage. Intracranial aneurysms can be either congenital, arising from birth, or acquired due to various factors over time. A vascular malformation encompasses a range of abnormalities affecting blood vessels, which can disrupt normal blood flow and lead to various complications. A carotid-cavernous fistula is a specific type of vascular malformation that represents an abnormal connection between the carotid artery—either external or internal—and the venous cavernous sinus, located behind the eyes. The procedure involves the insertion of a catheter through the skin into an access artery, which is then navigated to the carotid artery supplying the affected area. A microcatheter is subsequently advanced to the site of the aneurysm, malformation, or fistula. During the procedure, one or more coils or a balloon catheter with detachable balloons are introduced via the microcatheter. The deployment of the coil or balloon effectively occludes the aneurysm, malformation, or fistula, thereby interrupting blood flow. In the case of coils, the formation of blood clots around the coils further aids in blocking blood flow. Alternatively, an injection procedure may be utilized to achieve the same goal. Throughout the process, angiograms are performed to confirm the correct placement of the devices. Once the targeted area has been successfully occluded or the coils are securely in place, the catheter is removed, completing the procedure.
