Abstract
Background
Despite extensive research, the optimal approach for treating unruptured anterior circulation aneurysms (UACs) remains uncertain because of heterogeneous findings and limited robust data. To compare the outcomes of microsurgical clipping (MSC) with endovascular treatment (EVT) for UACs.
Methods
A systematic search was conducted in PubMed, Embase, Cochrane Library, Web of Science, and Scopus up to December 2024. Eligible studies included patients with UCAs treated with MSC or EVT. The primary outcomes were functional outcomes (mRS 0–2), recurrence rates, procedural complications, and mortality. Odds Ratios (OR) with 95% Confidence Intervals (CI) were calculated using a random-effects model. The Mantel-Haenszel method with a random-effects model was employed for the meta-analyses. All statistical analyses were conducted using R version 4.4.2.
Results
The analysis included data from 17 studies with 7,176 patients, of whom 3,810 (53.1 %) underwent EVT and 3,366 (46.9 %) received MSC. Complete occlusion rates were higher with MSC (OR 0.29; 95 % CI 0.15–0.56; p < 0.01), while procedural success also favored MSC (OR 0.42; 95 % CI 0.23–0.78; p < 0.01). Complications were less frequent with EVT, including serious adverse events (OR 0.53; 95 % CI 0.33–0.84; p < 0.01), vasospasm (OR 0.63; 95 % CI 0.44–0.89; p = 0.04), and thrombotic events (OR 2.23; 95 % CI 0.84–5.96; p = 0.12). However, EVT was associated with higher rates of residual aneurysms (OR 4.57; 95 % CI 1.75–11.97; p = 0.95), residual neck (OR 5.31; 95 % CI 2.81–10.02; p = 0.22), and need for retreatment (OR 5.65; 95 % CI 2.35–13.54; p = 0.99).
Conclusion
EVT offers advantages in reducing perioperative complications, while MSC provides greater long-term durability. Considering comparable functional outcomes and mortality, individualized treatment decisions should be based on patient profiles, aneurysm characteristics.
期刊介绍:
This International journal, Journal of Clinical Neuroscience, publishes articles on clinical neurosurgery and neurology and the related neurosciences such as neuro-pathology, neuro-radiology, neuro-ophthalmology and neuro-physiology.
The journal has a broad International perspective, and emphasises the advances occurring in Asia, the Pacific Rim region, Europe and North America. The Journal acts as a focus for publication of major clinical and laboratory research, as well as publishing solicited manuscripts on specific subjects from experts, case reports and other information of interest to clinicians working in the clinical neurosciences.
