Interventional cerebral aneurysm surgery is only part but not all of the treatment for cerebral aneurysms. For patients in the acute stage of hemorrhage, our emergency interventional treatment of aneurysm can achieve the goal of preventing rebleeding of aneurysm, but systematic or even long-term medical treatment is still needed after surgery, these treatments include dehydration to lower cranial pressure, antispasmodic, volume expansion, fluid replacement, functional rehabilitation, etc. Sometimes ventriculocentesis, lumbar puncture or lumbar pool drainage to release bloody cerebrospinal fluid is also necessary, and 3-4 weeks after hemorrhage some patients will develop delayed Traffic hydrocephalus, which may require surgical ventriculo-abdominal shunt to resolve. Cerebral aneurysms should be treated surgically. Approximately 70% of patients will die from aneurysm rebleeding if treated conservatively, and the risk is high. Microsurgery has now reduced the surgical mortality rate of aneurysms to less than 2%. We hope that you will pay attention to the knowledge about the interventional surgery of cerebral aneurysm. The timing of surgery is as follows: 1. Patients with Grade 1 or Grade 2 disease should be imaged as early as possible, and surgery should be performed within one week. Patients whose condition belongs to Grade 3 or above, suggesting serious bleeding, possible cerebrovascular spasm and hydrocephalus symptoms, are more dangerous to operate at this time, so wait for a few days for improvement and then operate. 2.Surgical method: craniotomy to clip the cerebral aneurysm tip is the most ideal method and should be preferred. Because it does not block the aneurysm-carrying artery, but also can completely and totally eliminate the aneurysm. Isolation surgery is to clamp the aneurysm-carrying artery at both ends of the aneurysm, which should be used with caution when the lateral branch supply of the brain is not proven to be good. The efficacy of aneurysm wall reinforcement is uncertain and should be used sparingly. For aneurysms that are not clinically suitable for surgery and are accessible by catheterization techniques, interventional treatment with balloon and spring-ring embolization is an option. Postoperative cerebral angiography should be reviewed to confirm whether the aneurysm has disappeared. It is important to understand the interventional procedure of cerebral aneurysm. 3.Treatment in the period to be operated: After aneurysm rupture, the patient should absolutely rest in bed, minimize adverse sound and light stimulation, and preferably place the patient in ICU for monitoring. Transcranial Doppler ultrasonography can monitor the changes of cerebral blood flow, which is helpful to observe the progress of the disease. Those with constipation should be given laxatives, maintain normal blood pressure, and be appropriately sedated. In case of cerebral vasospasm, early vascular protection therapy such as calcium antagonists can be tried. To prevent rebleeding by clot dissolution at the aneurysm rupture, larger doses of antifibrinolytic agents, such as aminocaproic acid, are used to inhibit the formation of fibrinolytic zymogens, but they should be used with caution in patients with renal dysfunction, because the side effects may lead to thrombosis. The knowledge about brain aneurysm intervention is very important for the treatment of your condition, so be sure to pay attention to it. Don’t ignore the information about the brain aneurysm intervention and wish you a speedy recovery.
