■脑血管的可视化,它们的分支和周围结构在脑血管手术中是必不可少的。基于吲哚菁绿染料的视频血管造影是脑血管手术中常用的技术。本文旨在分析ICG-AG的实时成像,DIVA,以及使用ICG-VA和Flow800来比较它们在手术中的有效性。
■术中实时识别29个前循环动脉瘤和3个后循环动脉瘤夹闭术中的血管和周围结构,一个STA-MCA旁路,对单独使用ICG-VA的患者进行了两次颈动脉内膜切除术,DIVA,ICG-VA与流程800详细分析和比较这些方法中的每一种。
■单独使用时,ICG-VA和DIVA无法显示23例脑动脉瘤夹闭的穿孔器。与添加Flow800的穿孔器相比,很容易可视化。在三种情况下,通过DIVA观察应用夹后穿孔器的闭塞,并通过重新定位手术夹来解决.在一次STA-MCA搭桥手术中,使用ICG-VA评估来自STA分支的MCA(M4)皮质分支的足够血流,DIVA,以及ICG-VA与Flow800颜色映射的使用。ICG-VA,DIVA,和Flow800在颈动脉内膜切除术中观察到血流缺乏和动脉粥样硬化斑块飘动。在一例基底动脉尖端动脉瘤中,我们将ICG-VA与Flow800一起使用;在确定感兴趣区域后绘制的强度图显示,夹闭后动脉瘤囊内无血流。
■在实时手术中,使用ICG-VA的多模式方法,DIVA,和ICG-VA与Flow800颜色映射可以作为用于更好地可视化血管和周围结构的有用工具。流800颜色映射的好处,例如确定感兴趣的区域,强度图,和彩色编码的图像,在手术过程中人类关键血管解剖结构的可视化方面,优于ICG-VA和DIVA。
UNASSIGNED: Visualization of cerebral vessels, their branches and the surrounding structures are essential during cerebrovascular surgery. Indocyanine green dye-based video angiography is a commonly used technique in cerebrovascular surgery. This paper aims to analyze the real-time imaging of ICG-AG, DIVA, and the use of ICG-VA with Flow 800 to compare their usefulness in surgery.
UNASSIGNED: Intraoperative real-time identification of vascular and surrounding structures in twenty nine anterior circulation aneurysms and three posterior circulation aneurysm clipping, one STA-MCA bypass, and two carotid endarterectomies were performed in patients using ICG-VA alone, DIVA, ICG-VA with Flow 800 to analyze and compare each of these methods in details.
UNASSIGNED: ICG-VA and DIVA couldn\'t visualize perforators in twenty-three cases of cerebral aneurysms clipping when used alone. Compared to that by adding Flow 800 perforators were easily visualized. In three cases, occlusion of perforators after clip application was visualized by DIVA and solved by repositioning surgical clips. In one STA-MCA bypass surgery, adequate blood flow to cortical branches of MCA (M4) from STA branches was assessed with ICG-VA, DIVA, and the use of ICG-VA with Flow 800 color mapping. ICG-VA, DIVA, and Flow 800 observed the lack of blood flow and fluttering atherosclerotic plaques in carotid endarterectomy. In one case of basilar tip aneurysm, we used ICG-VA with Flow 800; the intensity diagram drawn after determining regions of interest showed that there was no flow within the aneurysm sac after clipping.
UNASSIGNED: In real-time surgery, a multimodal approach using ICG-VA, DIVA, and ICG-VA with Flow 800 colour mapping can serve as useful tools for better visualization of vascular and surrounding structures. The benefits of flow 800 color mapping, such as determining regions of interest, intensity diagrams, and color-coded images, outweigh the advantages over the ICG-VA and DIVA in the visualization of critical vascular anatomy in humans during surgical procedures.
