Delayed Chronic Subdural Hematoma after Total Cranial Vault Reconstruction for Sagittal Synostosis

When diagnosed and treated after the first year of life, the surgical management of sagittal synostosis typically necessitates total cranial vault reconstruction. The safety of total cranial vault reshaping has improved greatly over the past 3 decades. We report on the first published case of an asymptomatic 5-year-old patient who was found to have a large left sided chronic subdural hematoma 4 months after total cranial vault reshaping requiring surgery, detected on routine imaging. We hypothesize that augmentation of venous blood egression through the emissary veins during surgery may have led to venous hypertension and subsequently the development of the chronic subdural hematoma.
