Background: Wide neck bifurcation aneurysms (WNBAs) are a subtype of aneurysms that are especially complex to treat. We aim to conduct a systematic review and meta-analysis to synthesize the available literature on the safety and efficacy of employing endovascular clip system (eCLIPs) in the treatment of WNBAs.
Methods: We report this study in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 guidelines. PubMed, Embase, Web of Science, and Scopus were queried for this review. Screening and extraction were performed by at least two authors to ensure accuracy and completeness, and a senior author arbitrated any discrepancies. All data were analyzed using R software version 4.3.0. and random-effects model.
Results: Four studies were finally included, of which three were prospective and one was retrospective. Successful adjunctive coiling occurred in 91.38% (95% CI = 70.71-97.9) of cases and overall technical success was achieved in 88.61% (95 CI = 75.54-95.15) of cases. The pooled complete occlusion (Raymond-Roy Class I) was 50.65% (95% CI = 39.63-61.60) and adequate occlusion (Raymond-Roy Class I/II) was 84.42% (95% CI = 74.53-90.93). Thrombo-embolic complication had a pooled rate of 1.22% (95% CI = 0.17-8.15), retreatment rate was 6.10% (95% CI = 2.56-13.83), and mortality reported in 3.66% (95% CI = 1.18-10.74) of patients.
Conclusion: The use of eCLIPs may be a safe and efficacious treatment for WNBAs. Future randomized controlled trials are needed for further validation of the findings.

Background And Objective: Cerebral aneurysms occur as balloon-like outpouchings in an artery, which commonly develop at the weak curved regions and bifurcations. When aneurysms are detected, understanding the risk of rupture is of immense clinical value for better patient management. Towards this, Fluid-Structure Interaction (FSI) studies can improve our understanding of the mechanics behind aneurysm initiation, progression, and rupture.

A 9-day-old male neonate was found to have a systolic murmur during a routine follow-up for skin jaundice. Imaging revealed a large mass at the bifurcation of the main pulmonary artery, causing significant bilateral stenosis. The patient underwent emergency surgery due to critically compromised pulmonary blood flow.

The Woven EndoBridge (WEB) device has become a prominent treatment for wide-neck bifurcation intracranial aneurysms since its FDA approval in 2018. However, the impact of anticoagulant therapy on its efficacy and patient outcomes remains underexplored. This study aims to evaluate the effects of postoperative anticoagulant use on aneurysm occlusion, retreatment rates, and functional outcomes following WEB device implantation.

Background: The risk of limb graft occlusion (LGO) after endovascular aneurysm repair (EVAR) is increased by severe tortuosity of the iliac artery. A bare metal stent (BMS) may protect LGO, according to the hypothesis of this single-center retrospective analysis.
Methods: All patients undergoing elective EVAR with a bifurcated stent graft between January 2012 and June 2022 were included in this cohort study.
