Abstract

AIM

Distal anterior cerebral artery (ACA) aneurysms are a rare and difficult entity to manage. In this single-centre retrospective case series, we aimed to investigate the safety and efficacy of LEO Baby stent-assisted coiling (SAC) for the treatment of unruptured distal ACA aneurysms.

MATERIAL AND METHODS

This retrospective study aims to identify patients with unruptured distal ACA aneurysms treated with LEO Baby stent-assisted coiling in a single institution from October 2018 to October 2022. We assessed the immediate and follow-up aneurysm occlusion rates, procedure-related complications, and clinical outcomes.

RESULTS

A total of 20 patients with 21 aneurysms were identified. Technical success was achieved in all cases. The immediate angiography showed complete occlusion in 14 aneurysms (66.7%), neck remnants in 6 (28.6%), and residual sac in 1 (4.8%). Procedure-related ischaemic complications occurred in 2 cases (10%), with one patient leaving mild contralateral low extremity weakness. Six-month follow-up angiography was achieved in 15 (71.4%) aneurysms, which showed complete occlusion in all 15 aneurysms. Clinical follow-up was available in all patients with a median duration of 18.8 ± 10.19 months, and all patients had a favourable clinical outcome (modified Rankin Scale score: 0–2).

CONCLUSION

This study demonstrates that stent-assisted coiling of intracranial aneurysms located on distal ACA with LEO Baby stents is technically feasible, highly effective, and has midterm durability in aneurysmal occlusion.
