[Intraoperative videoangiography using green indocyanine during aneurysm surgery]

Area of Science:

• Neurosurgery
• Vascular Surgery
• Medical Imaging

Context:

• Aneurysm surgery requires precise visualization of blood flow and vessel integrity.
• Traditional angiography provides only a postoperative assessment.
• Intraoperative techniques can offer real-time feedback during surgery.

Purpose:

• To evaluate the initial utility of intraoperative near-infrared indocyanine green (ICG) videoangiography in aneurysm surgery.
• To compare ICG videoangiography findings with postoperative angiography.
• To assess the accuracy of ICG videoangiography in confirming aneurysm occlusion and adjacent vessel patency.

Summary:

• Ten aneurysm clipping procedures were performed on nine patients using ICG videoangiography.
• The technique provided real-time visualization of aneurysm occlusion and surrounding vessels.
• ICG findings were compared with early postoperative angiography results.

Impact:

• ICG videoangiography accurately confirmed complete aneurysm occlusion in all cases.
• The technique demonstrated high concordance with postoperative angiography.
• It identified a case of moderate vasospasm not apparent during intraoperative imaging.
• No added neurological deficits were observed in patients.
• ICG videoangiography is a valuable, easily applicable tool for intraoperative assessment in aneurysm surgery.
