Brief Summary
The prevalence of unruptured intracranial aneurysm (UIA) in the population is about 2%-7%, and once it ruptures and bleeds, the rate of disability and death is extremely high, with 10%-15% of patients dying suddenly before they can seek medical attention, 35% of first-time bleeders, and 60%-80% of second-time bleeders. Survivors are often disabled. Therefore, there is a broad consensus that UIA with surgical indication should be aggressively intervened. The efficacy and safety of flow diverter (FD) in the treatment of UIA has been confirmed by many large clinical trials. Currently, FD placement for UIA is performed under general anesthesia (GA) in most centers, however, some studies have observed that FD placement under local anesthesia (LA) is not as effective as FD placement under general anesthesia and have demonstrated the feasibility of FD placement under local anesthesia (LA) with high technical success rates and low perioperative complication rates and mortality. However, the retrospective design and relatively limited sample size of the above studies may introduce significant bias and affect the confidence of the conclusions. Therefore, the present trial was designed as a randomized controlled trial with the aim of comparing the safety and efficacy of GA and LA in UIA patients undergoing FD placement. The results of this study will help inform future multicenter trials to validate the impact of anesthesia choice on the safety and efficacy in UIA patients undergoing FD placement.
