Simultaneous Dual Vessel Cerebral Angiography in Gamma Knife Planning

Abstract

Summary: Gamma knife radiosurgery is an effective technique for treating arteriovenous malformations. However, treatment failures can occur as a result of incomplete visualization of the arteriovenous malformation nidus. We describe the use of bilateral femoral artery catheterization and simultaneous dual vessel cerebral angiography to facilitate treatment planning during gamma knife treatment.
