A small bump, who did not care, but nearly led to big trouble. Recently, Zhaoqing Second People’s Hospital neurosurgery department came to a patient Chen moncler. A month ago, Master Chen’s head accidentally hit the corner of the table, the pain for a while and did not care. Recently, he suddenly felt headache, nausea, limb hemiplegia, to the second hospital examination only to learn that the small collision has led to chronic subdural hematoma. The director of the Department of Neurosurgery of the Second City Hospital, Fang Kai, introduced the chronic subdural hematoma is often due to the cerebral cortex to the sinus of the bridge vein tear, the early injury bleeding is small, will not immediately appear clinical symptoms, after more than three weeks, due to the continuous increase in blood and the formation of the envelope, compression of the surrounding brain tissue, before symptoms occur. The disease predominates in elderly patients, and its most important cause is craniocerebral trauma. Studies have shown that fibrinolytic enzymes play an important role in the formation of hematoma, and activation of fibrinolytic enzymes promotes fibrinolysis and inhibits platelet agglutination, thus inducing chronic hemorrhage, and brain atrophy and anticoagulation and antiplatelet drugs are also involved in its pathogenesis. The incidence of chronic subdural hematoma in the elderly accounts for about 30% of craniocerebral trauma in the elderly, and is a common craniocerebral injury in the elderly. The symptoms of chronic subdural hematoma often appear 3 weeks, months or years after the injury, and the common symptoms are: (1) symptoms of increased intracranial pressure: headache, vomiting, and optic nerve papillary edema. (2) Mental disorders: dementia, apathy, memory loss, disorientation, and mental retardation. (3) Focal brain symptoms: hemiparesis, numbness, aphasia, and focal epilepsy. The reason is that with the natural aging of the human body, the brain gradually shrinks, making the brain tissue volume shrink and the cranial gap become larger, which makes the intracranial buffer space of the elderly relatively larger than that of young people, and the tolerance to hematoma compression is stronger, so that elderly patients often have no obvious symptoms after head injury, and thus are easy to relax their vigilance. However, as the intracranial hematoma grows, the pressure on the surrounding brain tissues will gradually increase, leading to headache, dizziness, vomiting, blurred vision, memory loss, speech impairment, hemiparesis and even coma after a few weeks to months of injury, which can lead to life-threatening brain herniation in serious cases. Director Kai Fang suggests that the elderly should seek early medical attention and receive imaging CT and MRI examinations for symptoms after head trauma. Except for those with serious heart, lung and kidney dysfunction, once a simple chronic subdural hematoma is diagnosed, it is advisable to perform a drilling and drainage procedure to remove the hematoma as soon as possible, which is performed under local anesthesia and requires only one drilling with little trauma and satisfactory results. Chronic subdural hematomas of the segregated or mechanized type require craniotomy to remove the hematoma. The sooner the disease is operated, the less the brain tissue is damaged, the less the sequelae and the better the recovery. The Second People’s Hospital of Zhaoqing has three experts with associate titles or above and one attending physician, who standardize the treatment and rehabilitation of craniocerebral injury patients and treat cerebral hemorrhage according to individualized principles; they can perform various types of intracranial hematoma removal, intracranial tumor resection, hydrocephalus shunt, cerebrovascular disease (such as hypertensive cerebral hemorrhage, arteriovenous malformation, etc.) surgery, titanium mesh digital forming cranial repair, and also The department also performs microscopic neurosurgery and intravascular neurointerventional diagnostic treatment (whole brain angiography, aneurysm embolization, internal carotid artery cavernous sinus fistula embolization, early cerebral infarction arterial thrombolysis and other interventional surgical treatments have been carried out). The department is equipped with advanced examination equipment such as spiral CT, magnetic resonance (MR), cranial Doppler, electroencephalography and cerebrovascular digital subtraction angiography (DSA), which provides comprehensive and systematic guarantee for accurate diagnosis and treatment of neurosurgical diseases; it also has a German Leica f40 operating microscope, special operating bed for neurosurgery, surgical head rest, German Snake bipolar electrocoagulation, craniotomy power system, etc. Advanced surgical equipment, modern laminar flow operating room.
