Definition Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries. Blood pressure is continually changing depending on activity, temperature, diet, emotional state, posture, physical state, and medication use.

Cavernous sinus thrombosis is a blood clot in the cavernous sinus. The cavernous sinus is a cavity at the base of the brain that contains a vein, several nerves, and other structures. The vein carries deoxygenated blood from the brain and face back to the heart.

Causes, incidence, and risk factors
The cause of cavernous sinus thrombosis is usually a bacterial infection that has spread from the sinuses, teeth, ears, eyes, nose, or skin of the face. Persons with conditions that cause an increased risk of blood clots may also develop cavernous sinus thrombosis.
