Abstract
OBJECTIVE: The aim of the study is to report the feasibility, safety and outcomes associated with endovascular treatment (EVT) of unruptured intracranial aneurysms (UIA) under local anesthesia (LA).
METHODS: Between March 2011 and December 2016, 184 consecutive patients with 198 UIA were treated with coil embolization under LA at the author's center. The data about medical comorbidities according to American Society of Anesthesiologists (ASA) grade, procedural details, and clinical and radiographic outcomes were reviewed.
RESULTS: A total of 388 procedures were performed under local anesthesia, 198 procedures with UIA were included. The mean age was 63.8 ± 12.5 years and 118 (59.6%) cases had a risk status of ASA class III or IV. Of those 198 procedures, 196 procedures (99.0%) were completed successfully. The overall procedure-related event rate was 5% (10/198). The rates of morbidity and mortality were 0.5 % (1 of 198) and 0% at 1-month, respectively. There were three recurred cases (1.5%) and two (1%) of them underwent EVT again. The mean of ICU stay was 0.99 ± 0.1 days and the mean of postoperative hospital stay was 3.6 ± 7.2 days.
CONCLUSIONS: Local anesthesia in the EVT of UIA is feasible and safe. It could be considered as an alternative for the patients with high risk of general anesthesia.
