We describe the usefulness of intraoperative angiography (IOA) in identifying a recipient artery in extracranial-intracranial (EC-IC) bypass surgery. A 38-year-old woman presented with transient ischemic attacks that were resistant to aggressive medical treatment. Circulation delay at the M4 segment of the central artery was considered to be responsible for her symptoms. Due to the resistance to aggressive medical therapy, EC-IC bypass was planned. IOA was employed because of the need for definite detection of the central artery. The modality was helpful in determining the location of the skin incision and craniotomy as well as in identifying the recipient artery. The bypass was successfully constructed, and her symptoms were significantly reduced after the surgery.
