EXTRADURAL HAEMATOMA AT THE VERTEX

Abstract

The wider use of angiography in the investigation of cases of head injury in Bristol has revealed several cases of extradural haematoma at the vertex associated with raised intracranial pressure. It is submitted that a median extradural effusion at or near the vertex compresses the sagittal sinus, and, probably more importantly, the venous lacunae, resulting in a degree of engorgement of the hemispheres.
