Subdural haemorrhage has occurred due to venous bleeds. Which veins are involved (AIIMS Nov 2014)
1. Subdural haemorrhages result from rupture of cortical bridging veins. These connect the venous system of the brain to the large intradural venous sinuses and lie relatively unprotected in the subdural space.
2. The bridging veins drain the superior cerebral region and are also called as superior cerebral veins.
