Cavernous sinus thrombosis or thrombopheblitis causes clotting to occur in the cavernous sinus. This is one of the venous channels draining blood away from the brain produced where the dura, or linings of the brain, abut one another. In this sinus, however, not only does blood pass back to the heart from the eye and brain, but the carotid artery passes through the sinus as do several cranial nerves which control movements of the eye and sensation of the face. The cavernous sinus is located at the base of the skull, behind the eyes.
Causes of Cavernous Sinus Thrombosis
The condition is usually the result of infection of one of the sinuses of the skull.
Signs and Symptoms of Cavernous Sinus Thrombosis
A history of sinus infection with pain and tenderness is commonly elicited. Headache, fever and chills occur. The eye on the side of the head which is affected appears red, swollen and may bulge outwards. Double vision may occur associated with numbness around the eye or forehead.
