Combined DSA and 4D Flow Demonstrate Overt Alterations of Vascular Geometry and Hemodynamics in an Unusually Complex Cerebral AVM

Digital subtraction angiography (DSA) demonstrated a complex Spetzler-Martin grade 5 left parietal AVM supplied by multiple pial and dural arterial feeders with flow-induced intracranial aneurysms (notably along the basilar artery and anterior communicating artery complex). Additional DSA findings identified high-flow arteriovenous shunting, dural… (More)
