Thalamic hemorrhage may lead to brain herniation. Brain herniation is the displacement of part of the brain tissue due to intracranial pressure difference after an increase in intracranial pressure due to various reasons, and it is called brain herniation when the displacement exceeds a certain anatomical limit. Brain herniation can be caused by an intracranial hematoma caused by a thalamic hemorrhage, which compresses the brain tissue around it and increases intracranial pressure. When brain herniation occurs, early general treatment is needed, such as respiratory distress, tracheal intubation, mechanical ventilation, etc.; drug treatment, such as intravenous infusion of cranial pressure-lowering drugs, such as 20% mannitol, diuretics, etc.; surgical treatment, such as ventricular drainage, decompression of desmoid flap, cerebrospinal fluid shunt, etc.. It is recommended that patients with thalamic hemorrhage should go to regular hospitals in time and be treated under the guidance of doctors so as not to delay the diagnosis and treatment.
