The role of intraoperative videoangiography in aneurysm surgery—a comparative study from a tertiary care hospital

Abstract

Background Indocyanine green (ICG) is a near-infrared (NIR) fluorescent dye. After intravenous injection, it reaches the vessels of the brain within 30 s. A real-time visualization of the cerebral vasculature is possible. Results The infarction rate and the postoperative rebleed rate in the pre-ICG era group were higher than in the ICG era. Conclusion Intraoperative ICGVA is a safe and effective method to confirm the exclusion of the clipped aneurysm from the circulation. It also helps to assess the patency of the surrounding vessels.

Utilizing indocyanine green video angiography to bridge intracranial aneurysm treatment gaps in low- and middle-income countries: a mini-review

“…In a comparative study assessing periods before and after ICG-VA adoption, rebleeding incidents decreased significantly after ICG-VA implementation. 24 This reduction is attributed to the efficacy of ICG-VA in evaluating residual aneurysm filling, allowing precise clip adjustments along the aneurysm neck. 24 Additionally, open surgery in LMICs is linked to limited real-time feedback during surgery and longer operative times compared with high-income countries.…”
