Comparison of Intraoperative Indocyanine Green Angiography and Digital Subtraction Angiography for Clipping of Intracranial Aneurysms

摘要: Background: Residual aneurysm after microsurgical clipping carries a risk of growth and rupture. Digital subtraction angiography (DSA) remains the standard to determine adequacy clipping. Intraoperative indocyanine green (ICG) is increasingly utilized confirm optimal clip positioning across neck evaluate adjacent vasculature. Objective: We evaluated correlation between ICG DSA in clipped intracranial aneurysms. Methods: A retrospective study patients who underwent craniotomy aneurysms with for 2 years. Patient characteristics, presentation details, operative reports, pre- postclipping angiographic images were reviewed Results: Forty-seven postoperative DSA: 57 clipped; 23 (48.9%) presented subarachnoid hemorrhage. Nine demonstrated residual on not identified (residual sizes ranged from 0.5 4.3 mm; average size: 1.8 mm). Postoperative no branch occlusions. Conclusion: useful ensure gross patency vessels; however, presence subtle changes flow vessels best seen by DSA. This has important clinical implications regard follow-up imaging surgical/endovascular management.
