Under general anesthesia, intracranial aneurysm embolization was performed in the emergency department. After the operation, the patient had no unconsciousness and occasional psychiatric symptoms, and was given symptomatic treatments such as lowering the cranial pressure and relieving cerebral vasospasm, and the condition improved significantly one week after the operation, and the patient was transferred back to the local hospital for further treatment. Basic information] Female, 66 years old [Type of disease] Intracranial aneurysm [Hospital] Liaoning Provincial People’s Hospital [Time of consultation] July 2021 [Treatment plan] Embolization of intracranial aneurysm + medication (mannitol injection + edaravone injection) + lumbar puncture to release the cerebrospinal fluid [Cycle of treatment] Hospitalization for 1 week, and six months to the hospital for re-examination [Effect of treatment] The patient’s mental state was clear after the operation, and there was no consciousness disorder. After surgery, the patient was clear, without consciousness, and the angiogram showed good embolization and good visualization of the aneurysm-carrying artery. I. Initial Consultation The patient was admitted to the emergency department of our department because of a sudden headache for 6 hours, and was diagnosed with subarachnoid hemorrhage and came to the hospital for further surgical treatment after having a sudden headache, vomiting, and fuzzy consciousness 6 hours ago. The patient had no fever, no respiratory distress, and no food or water intake after the illness. Physical examination showed shallow coma, GCS score of 10, tingling can open the eyes, can pronounce, can not complete the command movement, tingling limbs flexion, Hunt-Hess grade 3, in the emergency head CT, the results returned subarachnoid hemorrhage, broken into the ventricle, ventricle mild dilatation, bilateral frontal lobe softening foci. The patient was admitted to the hospital and underwent emergency head CTA, which revealed an aneurysm of the upper segment of the left internal carotid artery, subarachnoid hemorrhage, bilateral frontal lobe soft foci, multiple limited calcified plaques in the siphon segments of bilateral internal carotid arteries, mild narrowing of the lumens of the arteries, and thinning of the A1 segment of bilateral anterior cerebral arteries, which was considered to be related to the aneurysm and the aneurysm had a diameter of 1.2 cm, which was in line with the indications for the surgery, and the patient and his family were explained to the patient and his family. After completing the relevant preoperative preparations and explaining to the patient and his family, intracranial aneurysm embolization was performed under general anesthesia in the emergency department. After the operation, a suitable spring coil was selected for dense filling, and the imaging showed good embolization and good visualization of the aneurysm-carrying artery. After the operation, the patient was given mannitol injection to lower the cranial pressure, lumbar puncture to release cerebrospinal fluid to lower the intracranial pressure, and edaravone injection to alleviate vasospasm, and the patient was relieved significantly after 1 week. The patient’s intracranial aneurysm embolization was found to have disappeared, the tumor embolization was dense, and the tumor-carrying arteries were well visualized on imaging immediately after embolization of the intracranial aneurysm. After the operation, the patient’s symptoms of vomiting and coma disappeared, and she had occasional headache and mental symptoms, and the patient’s uncomfortable symptoms were gradually relieved after being given symptomatic treatments such as standardized cranial pressure lowering and relief of cerebral vascular spasm, etc. The patient’s symptoms were obviously relieved after 1 week, and she was free of unconsciousness, no mental symptom, and the CTA of her head suggested that the aneurysm had been completely embolized, and there was no related stenosis or spasm of the vessels, and no serious complications such as acute cerebral ischemia and cerebral hernia occurred, and the overall effect was satisfactory. The overall effect was satisfactory, and the patient was discharged with no obvious complaints of discomfort at the time of hospitalization for 1 week, and was advised to come to the hospital for review in half a year. After treatment, the patient’s symptoms were relieved, but after discharge, the patient should pay attention to the following points: 1. After aneurysm surgery, regular follow-up is required, and it is recommended to have an angiography review after half a year, and pay attention to the control of blood pressure, which should not be too high, as it will induce aneurysm reoccurrence, and part of the patient needs to take antiplatelet drugs for half a year orally, so pay attention to the risk of bleeding. 2. After discharge, the patient should regulate his living habits as much as possible. Living habits. They should absolutely quit smoking and drinking, eat more light diet, avoid eating high-calorie food, eat more high-quality protein, eat more fresh fruits and vegetables, try to eat less food rich in high fat such as crab roe and arterial viscera, pay attention to less oil and salt when cooking, and pay attention to rest, regulate the mentality, and have regular rechecks. V. Personal Insights Intracranial aneurysm is the most common cause of cerebral hemorrhage in clinic. With the development of minimally invasive technology, most patients can also avoid solving aneurysm through craniotomy, which greatly reduces the risk of surgery. Most patients with aneurysms have no symptoms before rupture, and once rupture causes cerebral hemorrhage, it will greatly reduce the long-term survival rate and quality of life. In addition, for aneurysm patients, strict control of blood pressure, regular diet, proper eating and living habits, absolute abstinence from smoking and alcohol, adjusting the mindset and avoiding anger are especially important in their lives.
