Abstract
This study is a systematic review about the WEB device and addresses the efficacy and safety of this device for the endovascular treatment of ruptured and unruptured intracranial aneurysms. Material and methods This systematic literature review followed PRISMA-P guidelines and included studies published until 2010. PubMed and ScienceDirect databases were searched, resulting in 22 articles meeting the inclusion criteria. Results The studies involved 1705 patients and 1224 aneurysms, predominantly wide-neck aneurysms in the middle cerebral artery, internal carotid artery, and basilar artery. The treatment success rate was 28.1%, with the WEB-SL and WEB-SLS devices being commonly used. The immediate post-treatment adequate occlusion rate was 33.3%, increasing to 49.7% at follow-up. Thromboembolic complications occurred in 6.5% of cases, while other complications were observed in 3.1% of cases. The mortality rate associated with the WEB device was low, approximately 1%. Conclusion The WEB device demonstrates favorable outcomes in treating patients with intracranial aneurysms, with adequate occlusion rates improving over time. Thromboembolic complications are the primary concern, but overall complication and mortality rates remain low. Further research is needed to optimize device selection, standardize classification systems, and enhance long-term evaluation and training protocols.
