Cranial venous outflow obstruction, also referred to as impaired cranial venous outflow, impaired cerebral venous outflow, cerebral venous impairment is a vascular disorder that involves the impairment of venous drainage from the cerebral veins of the human brain.[1][2]
The cause of cranial venous outflow obstruction is not fully understood. It is believed to be associated with various factors including anatomical abnormalities, thrombosis, posture, and increased intracranial pressure.[3]
The obstruction can occur in any part of the venous system involved in draining blood from the brain, like vertebral venous system (VVS) or cerebral venous sinus (CVS), but it is most commonly seen in the dural venous sinuses.[4]
