Video Summary

Dr. Javier Fandino compares three-dimensional cerebral angiography (3D DSA) and indocyanine green (ICG) for intracranial aneurysm surgery. The study analyzed 140 cases, focusing on patient demographics, aneurysm characteristics, ICG and 3D DSA findings, and the need for clip readjustment. The results showed a 24% intraoperative reposition rate after using both techniques. Dr. Fandino presented several cases in which the 3D DSA identified remnants or required clip readjustments that were not detected in other imaging modalities. He concludes that 3D DSA, including intraoperative use, should be considered the gold standard for aneurysm surgery, potentially eliminating the need for postoperative DSA. The study was conducted in Aaron, Switzerland.
