Abstract BACKGROUND AND IMPORTANCE: Indocyanine green angiography (ICGA) has become a useful intraoperative tool during aneurysm surgery to determine parent, branching, and perforator vessel patency. Although extremely useful, ICGA is limited to the evaluation of vessels that are in direct view in the surgical field. CLINICAL PRESENTATION: We present 2 cases of patients who underwent a craniotomy for clipping of unruptured posterior communicating artery aneurysms. A Yaşargil movable mirror was used as an adjuvant to ICGA to visualize the ventromedial posterior communicating vessels after clip placement to determine vessel patency. CONCLUSION: Although ICGA can be very useful during aneurysm surgery, it is limited to vessels directly visualized in the surgical field. A Yaşargil movable mirror can be used during ICGA to visualize elusive vessels, in these cases on the ventromedial surface of the internal carotid artery.

AbstractMicroscope-integrated indocyanine green video-angiography (mICG-VA) is used as an adjunct to aneurysm surgery in checking for small compromised perforating arteries and the remnant of an aneurysmal neck. A limitation of mICG-VA is the inability to access the deep area where small vessels are located behind the aneurysm sac or the parent artery. The endoscope-integrated ICG-VA (eICG-VA) is not only a tool in obtaining a wide angle of surgical view, but also is a technique to detect real-time blood flow during aneurysm clipping.Patients with an unruptured cerebral aneurysm who had conventional endoscope-assisted microsurgery and eICG-VA were enrolled. We compared the efficacy and additional details of imaging from both types of procedures.The data of seven patients were reviewed. In two cases of small perforating arteries that were hidden by the aneurysm sacs, more details were detected by eICG-VA. While the performance of the conventional technique was limited, the eICG-VA revealed a wide view in the deep area during aneurysm clipping.The eICG-VA provides more details of the aneurysm, especially in small perforating vessels that were hidden by the aneurysm. It can resolve the limitations of the conventional endoscope and mICG-VA.
