Abstract
Introduction
The evaluation of clipped intracranial aneurysms postoperatively is crucial for successful
surgical treatment and minimizing risks such as residual aneurysms and complications.
Fluorescein sodium videoangiography (FL-VA) has been introduced to aid in this assessment,
but comparative studies with postoperative imaging remain limited.
Materials and Methods
A prospective observational study was conducted on 57 patients with 64 intracranial
aneurysms who underwent surgery between December 2021 and September 2022. FL-VA was
performed, followed by postoperative computed tomography angiography (CTA). Discordance
between FL-VA and CTA findings was analyzed statistically.
Results
FL-VA showed complete occlusion in 57 out of 61 aneurysms (93.4%), with 10 cases of
discordance identified in postoperative CTA. One patient showed a neck remnant in
FL-VA, but CTA revealed a residual aneurysm. Another patient displayed neck remnant
and stenosis in branching vessels on CTA, not identified by FL-VA. Additionally, five
aneurysms had neck remnants, and three had stenosis in branching vessels, detected
in CTA but missed in FL-VA. Statistical analysis did not reveal significant associations
between discordance and studied factors.
Conclusion
FL-VA shows potential as an effective intraoperative assessment tool for clipped intracranial
aneurysms, although further research is needed to establish its definitive efficacy
and reliability compared with other modalities.
