    Author: Yamakami I, Hirai S, Ono J, Yamaura A, Karasudani H, Uozumi A.
    Journal: No To Shinkei; 1997 Sep; 49(9):834-9. PubMed ID: 9311002.
    Abstract:
    We report three patients with dural arteriovenous malformation (DAVM) in the posterior fossa presenting the venous ischemia and the pathophysiology and the clinical characteristics of DAVM presenting the venous ischemia are discussed. Associated with occlusive changes in the venous sinuses, DAVM in the posterior fossa develops the venous hypertension of the straight sinus and the venous ischemia of cerebral white matter and basal ganglia. The venous ischemia presents progressive symptoms consisting of dementia with or without the ensuing consciousness disturbance. Multiple parenchymal lesions and abnormally dilated and tortuous veins are the characteristic findings in MRI/CT.
