Subarachnoid hemorrhage due to ruptured intracranial aneurysms is associated with significant morbidity and mortality. Re-bleeding from ruptured intracranial aneurysms further diminishes outcomes, and the mortality exceeds 50%. To prevent re-bleeding, early interventions, including surgical clipping or endovascular coiling of aneurysms, are justified. Although a majority of aneurysms can be treated with either technique, the indication for endovascular treatment is expanding due to its noninvasive nature, improvements in available devices and accumulation of supporting evidence. However, surgical clipping of aneurysms has the advantage of excellent curability and technical superiority for giant aneurysms and dissecting aneurysms requiring revascularization with a bypass or other intracranial techniques. Craniotomy is also indicated for patients with an intracranial hematoma and those with a significant increase in intracranial pressure. Endovascular coiling of aneurysms is avoided in patients with significant renal dysfunction, contrast-induced allergies or severe atherosclerotic disease. Therefore, clipping of aneurysms is still an essential technique, which cannot be completely replaced by endovascular procedures. In this article, the perioperative management of patients with intracranial aneurysms including preoperative blood pressure control, sedation and analgesia, indications for surgery, technical strategies for clipping in both simple and difficult cases, and intraoperative monitoring will be discussed from a practical point of view.
