Comparing indocyanine green videoangiography to the gold standard of intraoperative digital subtraction angiography used in aneurysm surgery.

摘要: Object The purpose of aneurysm surgery is complete obliteration while sparing associated arteries. Indocyanine green (ICG) videoangiography a new technique that allows for real-time evaluation blood flow in the and vessels. authors performed retrospective study to compare accuracy ICG with intraoperative angiography (IA), determine if can be used without follow-up IA. Methods From June 2007 through September 2009, 155 patients underwent craniotomies clipping aneurysms. Operative summaries, angiograms, operative videos were reviewed. number, size, location aneurysms, IA findings, need clip adjustment after recorded. Discordance between was defined as demonstrating normal vessel flow, but post-IA showing either an aneurysmal remnant and/...
