To describe symptomatology and etiological factors of posterior fossa strokes involving only the basilar artery. (P3.257)

Conclusions:Muscle weakness, language changes were the primary symptoms recorded when patients presented with posterior fossa strokes involving only the basilar artery. LVAT and cardio-embolism were the primary etiologies. This study elucidates symptoms to look for when patients present with muscle weakness as well as language changes, and emphasizes the possibility of cardiac causes of posterior fossa strokes involving purely the basilar artery.Study Supported by:The patients evaluated with only basilar stroke and at least one of the following symptoms: 72.6% (53/73) muscle weakness, 64.4% (47/73) language changes, 40.0% (29/73) dysarthria, 23.3% (17/73) nausea/vomiting, 21.9% (16/73) sensory changes, 20.5% (15/73) vertigo, 20.5% (15/73) aphasia, and 11.0% (8/73) gait changes. Etiologies of only basilar stroke for 33 patients were recorded: 39.4% (13/33) were associated with LVAT, 27.3% (9/33) were cardio-embolic, 21.2% (7/33) were due to small vessel disease, and 12.1 % (4/33) were from dissection.Disclosure: Dr. Parand has nothing to disclose.
