Abstract
Patients with intracranial aneurysm (IA) are at high risk of cerebral hemorrhage, which is associated with high mortality. Craniotomy or interventional endovascular coiling are common treatment methods in clinical practice, depending on the patient's condition. However, the recurrence rate of IA after either method remains unclear. This meta-analysis was conducted to study the relationship between different treatment regimens and IA recurrence. PubMed, CNKI, Web of Science, Wan Fang, and VIP databases were used to identify studies on "intracranial aneurysm," "craniotomy," "endovascular coiling," and "recurrence rate." Included studies adhered to rigorous screening and diagnostic criteria, and statistical models were applied based on homogeneity testing. This study encompassed 28 articles, including five on craniotomy and 23 on endovascular coiling, published between 2007 and 2022; among 1,448 cases treated with craniotomy, 20 experienced recurrences (recurrence rate: 1.4%, 95% CI: 0.2%), while among 5,975 cases treated with endovascular coiling, 872 cases experienced recurrence (recurrence rate: 14.6%, 95% CI: 14%, 20%). High heterogeneity (87%) was observed in the endovascular coiling, likely due to differences in patient demographics and aneurysm characteristics. For IAs, although endovascular coiling has advantages in terms of lower trauma and faster recovery, its high recurrence rate warrants closer post-treatment monitoring. Despite being more invasive, Craniotomy may be preferable in specific cases, such as when treating aneurysms with complex shapes or challenging locations. Treatment choice should be individualized, and future advancements in endovascular coiling technologies may help reduce recurrence rates.
