When a patient is told that he has an intracranial aneurysm most people choose to receive treatment. But exactly how to go about treating it often bothers patients and families. There are currently two types of treatment in neurosurgery clinics, interventional and surgical. Interventional procedure is relatively simple, but the follow-up treatment after surgery is complicated; open surgery treatment is complicated at that time, and postoperative treatment is relatively simple. Patients after interventional procedures have a significantly higher recurrence rate than surgical clamping at the 10-year follow-up. For the elderly, frail and sickly patients, or those with poor preoperative systemic conditions, we recommend intervention as a priority; for the younger ones, surgery is still the mainstay for aneurysms located in the anterior circulation. In my experience, surgical clamping of aneurysms located in the internal carotid artery system is very effective as long as the preoperative systemic condition is good and the patient is young.
