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

Journal of Neurosurgery, 2013
OBJECT The purpose of aneurysm surgery is complete aneurysm obliteration while sparing associated arteries. Indocyanine green (ICG) videoangiography is a new technique that allows for real-time evaluation of blood flow in the aneurysm and vessels.

Velocity Criteria for Intracranial Stenosis Revisited: An International Multicenter Study of Transcranial Doppler and Digital Subtraction Angiography

Stroke, 2011
Background and Purpose— Intracranial atherosclerotic disease is associated with a high risk of stroke recurrence. We aimed to determine accuracy of transcranial Doppler screening at laboratories that share the same standardized scanning protocol. Methods—
