There was no evidence of mechanical obstruction of the ventricular system by the AVM nidus itself or a draining vein. However significant reflux into periventricular and trans-medullary veins was demonstrated. Following partial targeted embolization of the AVM, no further reflux was observed, the patient's clinical deficits resolved, and the hydrocephalus improved. We suggest a hydrodynamic disorder as a potential pathomechanism of hydrocephalus in this adult patient with an unruptured AVM.<\/jats:p>","DOI":"10.1177\/159101991101700212","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T09:10:34Z","timestamp":1484125834000},"page":"212-216","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Hydrocephalus Secondary to Hydrodynamic Disequilibrium in an Adult Patient with a Choroidal-Type Arteriovenous Malformation"],"prefix":"10.1177","volume":"17","author":[{"given":"J.O.","family":"Ebinu","sequence":"first","affiliation":[{"name":"Departments of Surgery and Medical Imaging, The University of Toronto Brain Vascular Malformation Study Group, The Toronto Hospital, Western Division;
