[Total removal through the ventricle in 2 cases of pallidocaudal arteriovenous abnormalities under deep hypotension].
Two cases of A.V.M. situated in the pallido-caudal area and directly nourrished by the anterior perforated space arteries have been investigated using three angiographic techniques: selective internal carotid angiography, angiotomography including pneumoencephalography and angiography under deep hypotension at 30 mm Hg (mean pressure) induced by sodium nitroprusside. These investigations led to the conclusion that the A.V.M. could be removed through the lateral ventricle. Both were radically removed using the retrograde technique under deep hypotension and the operative microscope. Both patients are alive without additional neurological deficit.
