Abstract
BACKGROUND
Endovascular treatment of intracranial aneurysms (EVTIAs) is increasingly popular due to its minimally invasive nature and high success rate. While general anesthesia (GA) has been the historical preference for EVTIAs, there's growing interest in local anesthesia (LA). However, concerns persist about LA safety for EVTIAs. Therefore, we conducted a systematic review and meta-analysis to assess LA safety for EVTIAs.
METHODS
Following PRISMA guidelines, we searched PubMed, Embase, and Web of Science databases. Pooled analysis with 95 % confidence intervals (CI) assessed effects, I2 statistics gauged heterogeneity, and a random-effects model was adopted. Conversion to GA, neurological or procedure-related complications, intraoperative intracranial hemorrhagic complications (IIHC), and mortality were assessed. Subanalyses for ruptured and unruptured cases were performed.
RESULTS
The analysis included eleven studies, 2,133 patients, and 2,369 EVTIAs under LA. Conversion to GA rate was 1 % (95 %CI: 0 to 2 %). Neurological or procedure-related complications rate was 13 % (95 % CI: 8 % to 17 %). IIHC analysis revealed a rate of 1 % (95 % CI: 1 % to 2 %). The mortality rate was 0 % (95 %CI: 0 % to 0 %). Subanalyses revealed similar rates in ruptured and unruptured subgroups, except for a slightly high rate of complications and IIHC in the ruptured subgroup.
CONCLUSION
Findings indicate that EVTIA under LA is safe, with low conversion and mortality rates, even for ruptured aneurysms. Complications rates, also in IIHC rates, are comparable to those reported for GA, emphasizing LA's comparable safety profile in EVTIAs. Considering these promising outcomes, the decision to opt for the LA approach emerges as meaningful and well-suited for the endovascular treatment of aneurysms. Beyond its safety, LA introduces inherent supplementary advantages, including shortened hospitalization periods, cost-effectiveness, and an expedited patient recovery process.
