Whether a brain hemangioma can be operated on depends mainly on the location, size, and shape of the hemangioma. Therefore, the simultaneous presence of four hemangiomas may also be treated surgically. In general, the key to determine whether a cerebral hemangioma can be operated is the patient’s own condition and the size of the hemangioma. If the patient is in good condition, has no contraindications to surgery, has a strong desire for treatment and the size and shape of the aneurysm meets the criteria for surgery, even multiple aneurysms can be operated on. If the aneurysms are of different sizes, there is an option to treat only the larger ones that are at risk of rupture. Untreated aneurysms are reviewed regularly. If the aneurysm is small and the patient has no obvious clinical symptoms, you may choose to have regular follow-ups and then have surgery after detecting a tendency for the aneurysm to increase in size. If the patient’s condition is not suitable for surgery or his or her general condition cannot tolerate surgery, surgery cannot be performed. Multiple aneurysms have more chances of bleeding than single ones, so it is advocated that it is better to treat one aneurysm than none, and better to treat all of them than just one. It is in the patient’s best interest to treat all aneurysms with a single incision in a single operation.
