 Ruptured cerebral aneurysms have a higher incidence of direct surgery-related adverse events compared to unruptured aneurysms owing to challenging surgical conditions, such as difficulties in surgical exposure, cerebral edema, and intraoperative aneurysmal rupture, that increase the intraprocedural difficulty. The most common surgical adverse event is intraoperative rupture, with uncontrolled ruptures(during pre-dissection or from a tear in the aneurysm neck)often resulting in poor clinical outcomes. The key strategies for intraoperative rupture include staying calm, controlling bleeding, and ensuring hemostasis through appropriate methods. Given the advances in endovascular therapy for intracranial aneurysms, the number of microsurgical procedures has been decreasing. Thus, neurosurgeons at each facility need to prepare and gain experience in handling intraoperative ruptures.
