Efficacy of fluorescein angiography assisted occlusion via lateral-orbital keyhole approach in internal carotid bifurcation aneurysms / 中华神经医学杂志

ABSTRACT

Objective:To investigate the efficacy and clinical experiences of fluorescein angiography assisted occlusion via lateral-orbital keyhole approach in internal carotid bifurcation aneurysms. Methods:The clinical data of 16 patients with internal carotid artery bifurcation aneurysms admitted to our hospital from January 2016 to December 2020 were retrospectively analyzed. All patients accepted fluorescein angiography assisted occlusion via lateral-orbital keyhole approach. The patients were followed up at one, 3, and 6 months after surgery by medical imaging. The therapeutic efficacy of these patients was assessed by Glasgow outcome scale (GOS). Results:All aneurysms in these 16 patients were clipped at one-stage operation. Intraoperative fluorescein angiography and FLOW 800 showed that the aneurysms were completely clipped without residual, and the blood flow of the parent artery and perforating arteries was unobstructed. Six months after surgery, 14 patients recovered well (GOS scores of 5), and 3 developed limb hemiplegia (GOS scores of 4).Conclusion:Intraoperative fluorescein angiography assisted occlusion via lateral-orbital keyhole approach is safe and effective in internal carotid bifurcation aneurysms.
