Small aneurysms of the ophthalmic segment of the internal carotid artery can be treated by close observation, conservative treatment and surgery. 1. Close observation: If the aneurysm is small and has no symptoms, it can be temporarily observed and regularly reviewed. 2. Conservative treatment: Conservative treatment is mainly for some unruptured cerebral aneurysms, or patients who refuse surgical treatment or are physically unable to tolerate it, and require conservative treatment, need to control the blood pressure, keep the bowel movement smooth, and avoid emotional excitement and so on. However, it should be noted that cerebral aneurysm has the risk of rupture, and once ruptured again and bleeding, it will jeopardize the patient’s life. 3. Surgical treatment: mainly for patients with cerebral aneurysm rupture and bleeding, interventional surgery can be performed to deal with the aneurysm. The ruptured aneurysm needs to prevent vasospasm, dehydration and other complications. It is recommended that patients with small aneurysms in the ophthalmic segment of the internal carotid artery should consult a doctor in time, and actively treat the aneurysm under the doctor’s guidance, so as to avoid delaying the condition and causing serious consequences.
