Abstract

Background: Ventriculoperitoneal shunting (VPS) is considered a risk factor for developing subdural hematomas (SDH). Treating cases of acute SDH (aSDH) in shunted normal‑pressure hydrocephalus (NPH) patients can be challenging, and data in this field are scarce. We report our experience treating shunted NPH patients presenting with aSDH. Methods: Eight patients, aged 73 ± 6 years, with a history of VPS for NPH, hospitalized because of aSDH were included in this study. We retrospectively analyzed data regarding patients’ clinical and radiological presentation, hospitalization course, the use of antithrombotics, and response to different treatment regimens. Results: Four patients had pure aSDH, three had acute on chronic SDH, and one had subacute SDH. Patients presented with GCS 13–15 and various neurological signs, mainly confusion and unsteady gate. Two cases improved following resetting of their programmable shunt valve to its maximal pressure setting. Six cases improved after evacuation of the hematomas, five of them were operated a few days after initially resetting of the valve pressure. Three patients were discharged home, whereas five were referred to rehabilitation. Extended Glasgow Outcome Scale scores at discharge and during long‑term follow‑up were 5 and 7, respectively. Conclusions: Treatment of patients with VPS for NPH, presenting with aSDH, may differ according to the neurological status, imaging, and clinical course. Treatment options include restricting shunt function, hematoma evacuation, or both.
