Patient: My mother had an attack on December 17 and was diagnosed with subarachnoid hemorrhage. She was treated conservatively in the hospital for 20 days and the blood was absorbed. Surgery, right? If it’s not a hemangioma, then how should I treat it and is it prone to recurrence? If economic conditions do not allow, CT angiography or MR angiography is recommended immediately, and if economic conditions allow, DSA is highly recommended. If the aneurysm is a brain aneurysm, craniotomy is one of the treatment methods. Nowadays, developed countries in Europe and America prefer to use minimally invasive interventional embolization treatment to cure the aneurysm without craniotomy, with less trauma and faster recovery! If the angiogram does not find an aneurysm, there are two possibilities: there are tiny aneurysms that are not detected or other hemorrhagic cerebrovascular disease, which must also be reviewed with symptomatic treatment; there is also a benign subarachnoid hemorrhage, which is relatively less dangerous and has a very low recurrence rate!
