Objective To investigate the significance of intraoperative indocyanine green（ICG） angiography during microsurgical treatment of intracranial aneurysm and improve the curative effect. MethodsThe clinical materials of 32 patients harboring 35 intracranial aneurysms were retrospectively analyzed.The intraoperative ICG angiography was performed before and after the clipping of aneurysm.According to the findings of ICG angiography,the clip was adjusted if necessary and when spasmodic vessels occur on operative area the papaverine hydrochloride soaked on.Postoperatively,CT scan identifies whether there was infarction and 3D-CTA or DSA confirm the complete aneurysm obliteration in 28 cases. ResultsDuring the microsurgical procedure,aneurysmal neck remnant was found in 3 cases,parent arteries stenosis in 4 cases,distal branch stenosis in 2 cases,spasmodic vessels in 7 cases.The clips were immediately adjusted until satisfactory blood flow was restored and papaverine hydrochloride was used on the operative areas.There were death due to cerebral heriation and multiple organ failure in 2 cases.Postoperative CT,3D-CTA or DSA in 28 cases found complete clipping of aneurysms,no parent arteries and distal branch stenosis,small area infarction in 3 cases. Conclusion ICG angiography could be used to judge whether the aneurysm is completely obliterated,the parent and distal artery is stenosis.This technique could aid in improvement of outcome for the patients with intracranial aneurysm.
