Are routine intensive care admissions needed after endovascular treatment of unruptured aneurysms?

Routine intensive care unit monitoring is common after elective embolization of unruptured intracranial aneurysms. In this series of 200 consecutive endovascular procedures for unruptured intracranial aneurysms, 65% of patients were triaged to routine (non-intensive care unit) floor care based on intraoperative findings, aneurysm morphology, and absence of major co-morbidities. Only 1 patient (0.5%) required subsequent transfer to the intensive care unit for management of a perioperative complication. The authors conclude that patients without major co-morbidities, intraoperative complications, or complex aneurysm morphology can be safely observed in a regular ward rather than being admitted to the intensive care unit.
