- W3183201062 abstract "<h3>Background</h3> Unruptured intracranial aneurysms are a relatively common disease entity with a relatively uncommon, yet potentially devastating, risk of rupture. Over the past three decades, the safety of neurointerventional techniques for the treatment of intracranial aneurysms has greatly improved and allow for rapid post-operative recovery. Despite this, neurointerventional treatments remain almost exclusively inpatient procedures. The purpose of this study is to assess the short-term safety profile of electively treated intracranial aneurysms in healthy patients as part of a feasibility study for the ambulatory treatment of intracranial aneurysms. <h3>Methods</h3> A retrospective analysis was performed on 200 sequential healthy adult patients with intracranial aneurysms treated via neurointerventional techniques in an elective fashion at a tertiary care center. Healthy adults were classified as having a CCI ≤ 4 and mRS ≤ 1. Patients with non-saccular aneurysm (e.g. fusiform, dissecting), posterior circulation aneurysms, and/or multiple aneurysms treated in the same setting were excluded from analysis. A descriptive analysis was then performed on outcome measures, including, intraoperative complications, 48-hour post-op clinical event, length of stay, and 30-day mRS. <h3>Results</h3> A total of 176 patients were included in the analysis with an average age of 52 years and an average CCI of 1.6. Aneurysm location included 116 ICA aneurysms (65.9%), 24 ACA aneurysms (13.6%), 21 MCA aneurysms (11.9%), and 15 PCoA aneurysms (8.5%). Neurointerventional techniques included primary coil (n=37, 21.0%), stent-coil (n=38, 21.6%), intravascular flow diversion (n=96, 54.5%), and intrasaccular flow diversion (n=5, 2.8%). 4 patients (2.3%) experienced intraoperative complications. 14 patients (8.0%) experienced a clinical event in the 48-hour post-operative period, with 9 (5.1%) of these being clinically significant. The most common clinically significant event was a groin hematoma (n=3). The highest proportion of clinically significant events occurred in the stent-coil group (4/38; 10.5%). The average length of hospital stay was 1.7 days. At 30-day follow-up only 1 patient (0.6%) had a documented mRS higher than prior to intervention. <h3>Conclusions</h3> The neurointerventional treatment of unruptured intracranial aneurysms in healthy patients is associated with a low risk of peri-operative and short-term complication. These results suggest that with properly selected patients, the neurointerventional treatment of intracranial aneurysms may be feasible in the ambulatory setting and further prospective analysis is recommended. <h3>Disclosures</h3> <b>M.
