What is the brain venous sinus thrombosis?
Cerebral venous sinus thrombosis is a type of cerebrovascular disease in which one of the venous cavities occurs, resulting in infarction or death of brain cells. This heart attack is more often known as stroke. Although symptoms depend on the site of sinus thrombosis, the symptoms commonly reported include headache, blindness and weakness. The diagnosis is confirmed by imaging modalities such as scanning computed tomography (CT) and magnetic resonance imaging (MRI). The treatment of the brain venous cavity of sinus thrombosis involves medical stabilization and thrombolytic therapy.
There are two main types of thrombosis based on the type of affected blood vessels. Arterial thrombosis involves artery and venous thrombosis involves veins and duralumin cavities or spaces. In arterial thromboembolic strokes, a blood clot is thrown into the arterial circulation, reaches the middle brain artery (MCA) and causes stroke. It is a difference from the brain venous cavity thrombosis where in sInus spaces are a blood clot. Different causes of this disease have been identified. Venous thrombosis of lateral or sagittal sinus may occur as a complication of prolonged use of oral contraceptive agents and pregnancy. Another cause is infection of paranasal and frontal cavities, usually from Staphylococcus. Trauma, whether because of accidents or neurosurgical procedures, can also cause brain venous dununus.
other factors that increase the risk of brain venous thrombosis of sinus, include inflammatory missions and the use of corticosteroids, deficiencies of anticoagulant proteins and blood diseases. People who have a systemic lupus erythematosus nebonephrotic syndrome is also exposed to an increased risk. Other factors include dehydration and housing at high altitudes. All these risk factors generally produce hypercoagulation and increase blood vulnerablea width to form a clot.
The primary regime of brain venous sinus thrombosis is the display. CT scan is often the first desired imaging modality, but provides limited information and is usually normal if bleeding is not present. However, it is important to eliminate suspicion of other conditions. Venography of magnetic resonance (MRV) provides a better view of the pattern of the heart attack and may show the absence of normal blood flow in the brain venous channels. MRV is generally the display of choices for durela venous cavities and brain veins.
Treatment of brain vein sinus thrombosis involves medical and surgical treatment. In the standby room, the patient's head is raised at an angle of about 30 to 40 degrees to reduce the intractlak to run. If seizures are present, anticonvulsants such as phosphate, sodium valproate or phenobarbital are injected. Anticoagulant or thrombolytic therapy is then initiated to restore venous blood flow and reduce intracranial pressure.
