Research Article: Predictors of shunt insertion in patients with aneurysmal subarachnoid haemorrhage—a single-centre retrospective analysis
Introduction:
Treatment for acute hydrocephalus following aneurysmal subarachnoid haemorrhage (aSAH) with an external ventricular drain (EVD) has been standard care since the mid-1980s [6]. However, when and how to discontinue the EVD have proven challenging. This is in part because 30–40% of patients with an EVD following aSAH will remain dependent on CSF diversion after the initial phase [1, 2, 18] but are hard to identify. Thus, premature removal of the EVD may increase the risk of subsequent hydrocephalus, render EVD…
