Outpatient treatment of cerebral aneurysms: A case series

BACKGROUND: Major advances in the endovascular treatment of cerebral aneurysms have reduced the incidence of intra- and postprocedural complications. The length of stay after treatment for incidental aneurysms remains between early next-day discharge and 2 days. We hypothesized that discharging patients the same day would not be associated with any increase in the rate of postdischarge adverse events. METHODS: We retrospectively reviewed the charts of patients who underwent an elective coiling procedure between 2015 and 2020 at three centers and were discharged from hospital on the same day as the procedure. Patients were clinically evaluated 6 h, 1 week, and 6 months after the procedure, with repeat cerebral angiography performed 1 year after the procedure. RESULTS: Eleven eligible patients underwent outpatient treatment of 12 aneurysms treated through the wrist. No complications were identified within 1 week of the procedure. Clinical evaluation 6 months after treatment also failed to reveal any complication associated with the procedure. Only one of the seven patients who underwent 1 year angiography required retreatment. CONCLUSION: It is possible to safely perform coiled embolization of cerebral aneurysms in select outpatients with unruptured cerebral aneurysms.
