Main symptoms: severe coma before operation, dilated pupils on both sides. CT diagnosis: The ruptured aneurysm led to subarachnoid hemorrhage, and the amount of hemorrhage was 100ml. Craniectomy was used for the first time to clamp the aneurysm and remove intracranial hematocele. Postoperative situation: the clamping operation was successful and no rebleeding occurred. On the fifth day after operation, intracranial pressure was high due to brain edema. The preoperative CT film showed that the midline was displaced and the cistern was gone, so the second operation was performed. The second craniotomy cleared hematoma and some necrotic cells, and intracranial decompression; Postoperative situation: the operation was successful, and the patient's condition was controlled, but he still did not recover. Drug therapy was used in the last two months after operation, including vasodilators, brain nutrition, wake-up drugs and broad-spectrum antibiotics. After tracheotomy, there was an infection in the lungs, and the patient coughed a lot of phlegm and had fever symptoms. At present, the pupil has no reflection on light and has swallowing action. The doctor said he was still in a moderate coma. Nearly a month ago, I had lumbar puncture and drainage, and my brain collapsed at that time. At present, CT examination shows that the ventricle is relatively large, the left hemisphere is normal, and the right hemisphere has softening focus and flaky low-density shadow, which is suspected to be hydrocephalus. Laboratory test results: Laboratory test results: Last hospital visit: How to upload: You can take a picture with a white light source as the background in "Upload My Medical Record" on the right side of the dialog box and upload it. Dr. Yu Xin answered 2010-03-10 23: 06: 46 According to the information provided, there was serious bleeding at that time and a cerebral hernia had formed. Although two operations have been performed, the brain stem and the posterior cerebral artery have been damaged, which is not easy to recover (as confirmed by the recent CT examination). Now that he has survived, the next step is to wake him up. What we can do is to provide him with the environment and conditions for recovery as much as possible. At present, the most important thing is to control lung inflammation. If the condition is stable (body temperature is normal and lung inflammation is controlled), ventriculoperitoneal shunt can be considered to treat hydrocephalus. The doctor solemnly reminded: because I can't see the patient face to face, I can't fully understand the condition. The doctor's advice is for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor!
