The procedure described by CPT® Code 75660 involves angiography of the external carotid artery, which is a critical vessel supplying blood to the head and neck. In this procedure, a physician performs a selective angiography, meaning that they specifically target one side of the external carotid artery, either the left or the right, rather than examining both sides simultaneously. The process begins with the insertion of a catheter, a thin, flexible tube, into the artery. This catheter is carefully navigated through the vascular system to reach the external carotid artery. Once in place, a contrast dye is injected through the catheter. This dye is essential as it enhances the visibility of the blood vessels during imaging. As the dye circulates through the artery, the physician captures a series of X-ray images. These images allow for detailed examination of the artery's structure and any potential abnormalities, such as blockages or malformations. The radiological supervision and interpretation of these images are crucial for diagnosing conditions affecting the external carotid artery and planning any necessary interventions.

The procedure is indicated for various conditions and symptoms related to the external carotid artery. These may include:
The angiography procedure involves several critical steps to ensure accurate imaging of the external carotid artery. The first step is the preparation of the patient, which includes obtaining informed consent and ensuring that the patient is in a comfortable position, typically lying on an examination table. The physician then identifies the appropriate access site, usually in the groin or wrist, where the catheter will be inserted. After cleaning the area with antiseptic solution, a local anesthetic is administered to minimize discomfort during the catheter insertion.
Following the angiography, the patient is monitored for any immediate complications, such as bleeding or allergic reactions to the contrast dye. The access site is typically bandaged, and the patient may be advised to rest for a short period. Depending on the patient's condition and the findings from the procedure, further follow-up may be necessary. Patients are often instructed to hydrate well to help flush the contrast dye from their system. Additionally, they may receive specific instructions regarding activity restrictions and signs of complications to watch for in the days following the procedure.
