Cerebral aneurysm surgery usually ranges from 1 hour to 6 hours, and the length of time mainly depends on the operation method and whether the aneurysm is ruptured or not.
1. Unruptured aneurysm with bleeding: in this case, the operation time is relatively short, usually takes 1 to 2 hours if the aneurysm is treated by endovascular intervention; if the aneurysm is treated by craniotomy, it takes about 3 to 4 hours.
2. The aneurysm has ruptured and hemorrhaged: in this case, hematoma will usually be formed, and the difficulty of the operation will be significantly increased. At this time, even through the endovascular intervention, the time will be prolonged, and it will take about 2 to 3 hours; if the hematoma is removed and treated through the craniotomy, it will take about 4 to 6 hours.
It should be noted that cerebral aneurysm is a more serious disease, and it is recommended that patients suffering from cerebral aneurysm should seek timely medical treatment under the guidance of the doctor, so as to avoid delays in the condition, which may lead to serious consequences.
