What is cerebral arteriovenous malformation and its dangers? Cerebral arteriovenous malformation is a congenital malformation within the brain or spinal cord. The main manifestations of patients are recurrent intracranial hemorrhage, partial or generalized convulsive episodes, transient ischemic attacks, or headaches, hemiparesis, and aphasia. How to treat cerebral arteriovenous malformations? The aim of surgical treatment is to correct the disturbance of cerebral hemodynamics, improve the blood supply to the brain, and strive to eliminate the risk of lesion rupture and bleeding, so that the original neurological dysfunction will gradually improve and the convulsive attacks can be expected to be reduced or alleviated. Currently, there are three main surgical treatments for cerebral arteriovenous malformations: interventional embolization, craniotomy of malformed masses, and radiation therapy. Interventional embolization is a minimally invasive treatment method that uses catheter technology to inject embolic material into the lesion to occlude, reduce, or delay congestion of the malformed mass, thereby achieving treatment. Craniotomy: Under general anesthesia, the skull is opened and the blood supply artery and drainage vein are directly cut off to remove the malformed vascular mass. Radiation therapy involves the precise concentration of gamma rays or X-rays to the site of vascular malformation for irradiation, resulting in thrombosis and thus occlusion of the malformed vascular mass. It is indicated for small vascular malformations that are deep in the area and cannot be reached by microcatheters and are also difficult to reach by craniotomy.
