Introduction
Cerebral venous sinus thrombosis refers to the formation of a blood clot within the intracranial venous sinuses, which can lead to venous wall injury, slowed blood flow causing blood stasis, and a hypercoagulable state. The causes of venous sinus thrombosis are mainly divided into infectious and non-infectious types. Non-infectious venous sinus thrombosis typically occurs due to significant dehydration, hypovolemia, the postpartum period, or hematological disorders that result in blood hemoconcentration.
Cerebral venous sinus thrombosis refers to the formation of a blood clot within the intracranial venous sinuses, which can cause damage to the venous wall, slow blood flow leading to blood stasis, and a hypercoagulable state. The causes of venous sinus thrombosis are mainly divided into infectious and non-infectious types; careful differentiation is recommended, and prompt medical treatment at a hospital is essential.
Non-infectious venous sinus thrombosis typically occurs due to significant dehydration, hypovolemia, the postpartum period, or hematological disorders that lead to blood concentration. The infectious type is usually associated with facial infections or inflammation of the cavernous sinus, which can increase blood viscosity and narrow blood vessels, thereby predisposing individuals to thrombus formation.
Once venous sinus thrombosis occurs, initial management includes fluid replacement and administration of antithrombotic medications, along with measures to reduce intracranial pressure. Since cerebral venous sinus thrombosis often leads to elevated intracranial pressure, drugs to lower this pressure should be used promptly to prevent severe headaches and other complications.
