title: Localization of velum interpositum AVM with metrizamide ventriculography and simultaneous stereoangiography. Case report.
abstract: The combination of metrizamide (Amipaque) ventriculography and vertebral angiography with stereoradiography provided precise localization of an arteriovenous malformation of the velum interpositum and an associated hematoma in the lateral ventricles that had not been detected by computerized tomography. This dual technique is recommended for precise localization of suspected intra- or periventricular lesions before surgery.
