Understanding Cavernous Sinus Thrombosis
Cavernous sinus thrombosis is a thrombophlebitic disease that often begins with a facial or sinus infection, leading to thrombus formation in the cavernous sinuses and obstructing venous drainage. It is a rare condition, with an annual incidence of 2 to 13 cases per million, typically affecting adults aged 20 to 50, with a mean age of 22 years. The disease has a mortality rate ranging from 10 to 30%, and neurological complications can occur in 50 to 75% of patients, making effective diagnosis crucial. Understanding the complex anatomy of the cavernous sinuses, influenced by nearby cranial nerves and arteries, is essential for recognizing how infections spread and cause thrombosis in this confined area.
