Cerebral Venous Sinus Thrombosis (CVST) Stroke Stories

Cavernous sinus thrombosis means a blood clot in the cavernous sinuses. The cavernous sinuses are hollow spaces behind each eye socket, under the brain. The jugular vein (a major blood vessel) carries blood through these cavernous sinuses and away from the brain.

An infection in the face or skull that spreads to the cavernous sinuses can cause blood clots to develop. They develop to prevent the infection spreading further but they can restrict the blood flow from the brain. This restriction can damage the brain, eyes and nerves running between them. Sometimes, clots can develop without infection.
