Aneurysm surgery mostly refers to intracranial aneurysm surgery. Intracranial aneurysm surgery may involve risks such as bleeding, cerebral vasospasm, and recurrence of the aneurysm. 1. Bleeding: whether it is intraoperative rupture bleeding or postoperative bleeding of intracranial aneurysm, it is one of the common surgical risks. 2. Cerebral vasospasm: The operation of aneurysm surgery may cause vasospasm, which may lead to cerebral infarction, cerebral ischemia, neurological dysfunction and other conditions. 3. Aneurysm recurrence: a few patients may have aneurysm recurrence after operation, because after intracranial aneurysm operation, there may be aneurysm neck residual or incomplete embolization, which will cause aneurysm recurrence. It is suggested that patients should go to the hospital for examination in time to determine the location and size of the aneurysm, and be given appropriate treatment and therapeutic methods under the guidance of doctors.
