Analysis of related factors affecting prognosis of shunt surgery in patients with secondary normal pressure hydrocephalus.

Objective: The management of secondary normal pressure hydrocephalus (sNPH) is controversial. Many factors may affect the surgery effect. The purpose of this study was to identify the possible factors influencing prognosis and provide theoretical basis for clinical treatment of sNPH.

Zero drift of intraventricular and subdural intracranial pressure monitoring systems.

Objective: To assess zero drift of intraventricular and subdural intracranial pressure (ICP) monitoring systems.

Methods: A prospective study was conducted in patients who received Codman ICP monitoring in the neurosurgical department from January 2010 to December 2011. According to the location of sensors, the patients were categorized into two groups: intraventricular group and subdural group.

Which side of lateral ventricles to choose during external ventricular drainage in patients with intraventricular hemorrhage: ipsilateral or contralateral?

Background: We attempted to investigate the effect of external ventricular drainage (EVD) plus intraventricular fibrinolysis from ipsilateral or contralateral ventricle on clinical outcomes in patients with intraventricular hemorrhage.

Methods: We undertook a prospective controlled study. Patients with acute obstructive hydrocephalus after intraventricular hemorrhage were randomized to receive EVD from ipsilateral ventricle (ipsilateral group [IG]) or contralateral ventricle (contralateral group [CG]).
