Overview of superior sagittal sinus thrombosis

Cerebral vein thrombosis is rare, and its causes are inflammatory and non-inflammatory, most of which are due to the spread of venous sinus thrombosis. Thrombosis of the inflammatory intracranial venous system is common in cavernous and sigmoid sinuses. Sigmoid sinus thrombosis is mainly caused by suppurative otitis media, mastoiditis, and the bone wall of the sigmoid sinus, forming a thrombus, or causing a vein in the vein leading to the sigmoid sinus to spread to the sigmoid sinus. Upper sagittal sinus thrombosis is often caused by frontal sinus, nasal inflammation, encephalitis, or brain abscess. Or caused by the spread of venous thrombosis of the transverse sinus, cavernous sinus, rock sinus, pterygoid plexus, etc. to the superior sagittal sinus.

Most of the sagittal sinus thrombosis is non-inflammatory, and it is related to factors such as pregnancy, consumption and cachexia. It is more common in young children, the elderly and mothers. The main clinical manifestations are increased intracranial pressure, damage to the upper frontal cortex, scalp vein bloating, and sigmoid sinus thrombosis.

Description of superior sagittal sinus thrombosis

Most of them are non-infectious, in view of severe dehydration and cachexia in maternal, gestational, infants or the elderly at 1-3 weeks postpartum; infectivity is rare.

Signs and symptoms of superior sagittal sinus thrombosis

Acute or subacute onset, common systemic weakness, increased intracranial pressure as the first symptom, forehead edema, no focal fire formation of nerve signs. Infants and young children can see cranial suture separation, superficial frontal venous tortuosity, elderly patients with mild symptoms, only headaches, dizziness, etc .; some patients have focal or generalized seizures early. Hemiplegia, anaesthesia, dark occlusion (occipital cortex), bladder insufficiency, and paralysis of the lower extremities (involvement of the lateral central lobules) can occur. Cerebral pressure increased, CSF white blood cells, protein increased.

Causes of superior sagittal sinus thrombosis

Obstruction of the superior cerebral vein flow into this sinus leads to severe edema, bleeding and softening of the cerebral cortex.

Pathophysiology of superior sagittal sinus thrombosis

Obstruction of the superior cerebral vein flow into this sinus leads to severe edema, bleeding and softening of the cerebral cortex.

Treatment of superior sagittal sinus thrombosis

The treatment of this group of diseases is first to reduce dehydration and reduce intracranial pressure and control seizures. Broad-spectrum antibiotics can be used to treat septic thrombosis. Anticoagulants and thrombolytic drugs can be used to treat sterile thrombosis, which may promote recanalization and improvement Clinical prognosis, but the efficacy is not fully confirmed; because of the possibility of inducing intracranial hemorrhage, the case should be strictly selected, and the condition should be closely observed and detected.
