To tell the truth, the risks and sequelae of surgery are much more serious than interventional therapy. Because of intracranial lesions, the surrounding tissues may be damaged after operation, causing irreversible damage. Interventional therapy is minimally invasive and the recurrence rate is very small, mainly depending on the quality of your blood vessels and your blood pressure. Even surgery is at risk of recurrence. But you need to consider the cost, because the number of coils to be put in depends on the size of your aneurysm, and the size of the aneurysm depends on the angiography at the time of intervention. If your aneurysm neck is very small, you don't need to put a stent, it may take about 3-4 laps, and the cost is 40,000-60,000. If the bracket is placed, it may take 80-120,000.
