Recurrent Chronic Subdural Hematomas in Normal Pressure Hydrocephalus Patient Shunted with Nonprogrammable Shunt

Subdural hematoma (SDH) can occur as a complication of ventriculoperitoneal shunt (VPS) in normal pressure hydrocephalus (NPH) cases. The prevalence of shunt-related complications involving over-shunting in NPH varies considerably in many studies. The decreasing size of the ventricles that occurs in NPH patients who have undergone VPS may result in stretching of the bridging veins in the subdural space causing them prone to bleeding that is caused by slightly minor traumas. An 87-year-old male patient presented with a chief complaint of weakness in the left half of the body since 1-day before admission. In addition, cough, fever, and shortness of breath were also reported by the patient 3 days before admission. From history taking and diagnostic procedure we found that the patient had recurrent chronic SDH (CSDH). Previously the patient was diagnosed with NPH and had undergone VPS procedure 6 months before. The patient also tested positive for COVID-19. The patient has undergone burr hole drainage with 1-hole only and without irrigation, followed by the removal of VPS suspected as the cause of recurrent CSDH.
