Comparison of lattice and pipeline flow diverters for the treatment of distal intracranial aneurysms: an inverse probability of treatment weighting analysis

1

This study compared the efficacy and safety of Lattice and Pipeline flow diverters for treating unruptured distal intracranial aneurysms.
2

A total of 47 patients were included, with follow-up imaging conducted at 6 months postoperatively using CTA or DSA.
3

Aneurysm occlusion rates were similar between the Lattice (77.8%) and Pipeline (75.9%) groups, with no statistically significant difference.
4

Branch vessel occlusion rates were also comparable, with 16.7% in the Lattice group and 6.9% in the Pipeline group, but not statistically significant.
5

Factors such as inflow angle, aneurysm neck diameter, and branch vessel origin were associated with incomplete or delayed aneurysm occlusion.
