Intercavernous sinus disorders refer to problems that occur in the intercavernous sinuses, which are venous channels (veins) located between the two cavernous sinuses at the base of the brain. These channels help drain blood from the brain back to the heart. Disorders in this area can affect blood flow, leading to various symptoms and complications.
Types of Intercavernous Sinus Disorders
- Thrombosis: Blood clots forming in the intercavernous sinus.
- Aneurysm: Abnormal bulging in the wall of the intercavernous sinus.
- Fistula: Abnormal connection between an artery and the intercavernous sinus.
- Infection: Bacterial or viral infections affecting the intercavernous sinus.
- Inflammation: Swelling and irritation of the sinus.
- Trauma: Injury to the intercavernous sinus.
- Tumors: Growths that affect the intercavernous sinus.
- Congenital anomalies: Birth defects involving the sinus.
- Vascular malformations: Abnormal blood vessel formations in the sinus.
- Hypercoagulable states: Conditions that increase blood clotting risk in the sinus.
