General information shows that the incidence of intracranial aneurysm is between 3-5%, which means that 3-5% of the whole population has intracranial aneurysm, and the annual rupture rate of these aneurysms is about 1%, and the mortality rate after the first rupture is about 30%. In terms of the above figures, it is indeed scary, firstly because of the high incidence of aneurysms and secondly because of the high mortality rate once they rupture and bleed. Is it necessary for everyone to have a medical checkup to see if they have an aneurysm? Is it necessary to treat it once it is found? What treatment method should be used? Can it be cured? First of all, it should be clear that compared to cancer, aneurysm is a benign disease, which is preventable and treatable. However, it is characterized by malignant manifestations and has serious consequences once it ruptures. In general, if the aneurysm is not due to bleeding, but is found occasionally, treatment should be considered for the following characteristics: size larger than 5 mm, irregular morphology, posterior circulation, causing occupying effect but no bleeding, younger patient, and heavy psychological burden. For the general ones, they can be reviewed periodically, with half-yearly or yearly checkups, and if there is no significant change, they should continue to be observed; if they grow significantly, they should be treated urgently, and if they cause clinical symptoms, they should also be treated urgently. Treatment methods include access embolization and neurosurgical clamping. For the vast majority of aneurysms both approaches are possible with comparable results. Interventional treatment is less invasive, has a quick recovery, and does not affect normal nerves, but can be more costly. Neurosurgical clamping is slightly more invasive and less expensive. You can choose according to your situation.
