Recently, the Department of Neurosurgery performed a minimally invasive surgery – borehole drainage – on a nearly 100-year-old man. The patient recovered well after the operation and will be discharged from the hospital soon. The patient came from the city, although he was already 98 years old, but usually lives completely on his own. 1 month ago, he suddenly developed weakness of the left limb, unstable walking, and gradually developed uncontrollable urination, and he went around several hospitals, but none of them could make the old man’s symptoms improve. The patient and his family were very anxious and worried when they heard the news. The deputy director patiently explained the occurrence of the disease and the advantages and disadvantages of the treatment methods to the patient and the family, and little by little, the patient and the family were relieved of their worries. After discussion, the family agreed to Dr. Wang’s suggestion of surgery; however, at the age of 98, the family was still a bit worried. Dr. Wang again patiently and meticulously explained to the family the risks and prognosis of the surgery and analyzed the pros and cons. The family finally decided to operate, and Dr. Wang actively contacted the operating room and the anesthesiology department and decided to perform emergency surgery under general anesthesia. The patient was pushed into the operating room, and the family waited anxiously at the door of the operating room. An hour later, the patient was pushed out of the operating room and the operation went well; another hour later, the patient woke up and everything was fine; the next day the old man was able to walk on the ground. The patient’s family held Dr. Wang’s hand tightly. They really didn’t expect the patient to recover so fast!

There is no uniform understanding of the source and pathogenesis of hematomas. Hematomas often occur on the convex surface of the frontoparietal temporal hemisphere, with an accumulation of up to 100 mL or more of blood, and are more frequent in the elderly, who often deny a history of trauma. The clinical manifestations are mainly increased intracranial pressure, headache is more prominent, and some of them have mental symptoms such as dementia, apathy and mental retardation, but also focal neurological symptoms such as hemiparesis, aphasia, incontinence and focal epilepsy; cranial CT or MRI can make a clear diagnosis, and surgical treatment is generally used, and conservative treatment is not effective.
