A cerebral arteriovenous malformation may not be detected until it bleeds. The bleeding caused by a ruptured cerebral arteriovenous malformation is called a subarachnoid hemorrhage. An unruptured cerebral arteriovenous malformation may be treated, depending on the size of the aneurysm, location, and a person's age.

Treatment for cerebral arteriovenous malformation may include:

• Surgery for cerebral arteriovenous malformation
• A clip closes the abnormal communication between the artery and the vein
• Endovascular embolization for cerebral arteriovenous malformation
• A catheter is used to insert a plug, in order to close the abnormal communication between the artery and the vein.
• Focal beam radiation for cerebral arteriovenous malformation:
• Small doses of radiation gradually closes the aneurysm.
• Cerebral arteriovenous malformation clinical trials

Treatment for subarachnoid hemorrhage may include:

• Intravenous fluids
• Oxygen therapy
• Medication for cerebral aneurysm
• Surgery for cerebral aneurysm
• Cerebral aneurysm clinical trials
