A case of Hemiplegia Vegetativa Alterna, Paroxysmal Sympathetic Hyperactivity and Ogilvie's Syndrome: the role of central sympathetic pathways in their pathophysiology

Meeting Theme: Degenerative Lumbar SpineOral-Poster Presentation 1Hemiplegia vegetativa alterna (HVA) is the clinical syndrome of contralateral hemiparesis, hemisensory loss, hemihyperhydrosis and ipsilateral Horner’s syndrome1,2. The term vegetativa alterna denotes that a single brainstem lesion manifests with ipsilateral and contralateral, i.e. crossed, signs of autonomic (“vegetative”) sympathetic nervous system dysfunction. Fewer than five cases have been reported and most were a result of stroke involving the occlusion of posterior cerebral artery (PCA) perforators that supply the anterolateral mesencephalon. We describe a 46 year old male who suffered from aneurysmal subarachnoid hemorrhage and exhibited HVA as …published_or_final_versio

Territory-wide ventriculoperitoneal shunting outcomes from 2009 to 2011: Multicenter Hospital Authority Clinical Audit

Free paper 7Meeting Theme: Degenerative Lumbar SpineVentriculoperitoneal (VP) shunting for the management of hydrocephalus is one of the most common procedures performed in daily neurosurgical practice. Although surgical techniques and perioperative management have reduced the incidence of shunt failure, the procedure is still fraught with potential complications. Approaching a third of adult patients (29%) experience shunt failure within the first year and as high as 59% of patients regardless of age require shunt revision during their lifetime1. The aim of this study is to determine the rate of shunt failure in Hong Kong’s public health system and identify its causes as well as risk factors …published_or_final_versio
