Brain aneurysm can be treated by intervention, which can be embolized with a spring ring and stent can be placed, and the stent is carried for life and does not need to be removed. After the stent and aneurysm surgery, the aneurysm is completely cured after the review of the aneurysm embolization, which does not affect the future life expectancy and can be survived for a long time. Aneurysms in the brain can have some residuals after intervention, which can easily recur later. Once an aneurysm recurs, it can rupture and bleed again, which can be life-threatening. After stenting and embolization, it is important to pay attention to regular review. 3 months after the surgery, a cerebral angiogram is required to determine whether there is residual.
