Objectives: To evaluate the clinical features, radiological diagnosis of giant cerebral arteriovenous malformation (AVM). Methods: This prospective study imlpemented 26 patients admitted at Viet-Duc hospital and Bach Mai hospital between 6/2008-3/2014. Results: Female/male: 1/1.9. The clinical presentations are found with epilepsy 53.8 percent, headache 23.1 percent. On scanner, 34.6 percent canxification, and hemorrhage 19.2 percent. All AVM situate at level of cortical and subcortical region and 23.1 percent at fronto-temporal region and 23.1 percent at fronte-parietal region. 100 percent of AVM are feeded by many resources, among these, 57.7 percent have two and 42.3 percent have three feeding cerebral arteries. 84.6 percent of patients have some draining veins and drainage to deep venous system was 23.1 percent, aneurysms associated on the feeding arteries was found in 11.5 percent. Conclusions: Giant AVM often occurs young, male patients, with epilepsie severe headache. Ruptured complication was rare. Scanner shows mixed hypo-hyperdense and canxification. Angiography reveals a arterious blush at the level of fronto-parietal and frento-temporal regions, feeded by many resources including middle, anterior and posterior cerebral arteries. These AVM usually get many draining veins which come back to superficial and deep venous systems.
