Neuroanesthesia for embolization of a ruptured cerebral aneurysm: clinical practice guidelines

When the neuroanesthesia working group of the Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor surveyed Spanish anesthesiologists to learn the degree of their involvement in the diagnosis and treatment of spontaneous subarachnoid hemorrhage, a surprising finding was that anesthetists did not participate in endovascular repair of intracranial aneurysms when the procedure was carried out in an interventional radiology department. These interventions, which are considered minimally invasive and are performed outside the operating room, are not risk-free. Based on the survey results and a systematic review of the literature, the working group has provided practice guidelines for the perioperative management of anesthesia for endovascular repair of ruptured cerebral aneurysms. In our opinion, the diversity of practice in the hospitals surveyed calls for the application of practice guidelines based on consensus if we are to reduce variability in clinical and anesthetic approaches as well as lower the rates of morbidity and mortality and shorten the hospital stay of patients undergoing exclusion of an aneurysm.
