Popis: We retrospectively evaluated the relationship between the collateral pathway defined 3D Time-of Flight Magnetic Resonance Angiogram (MRA) and intraoperative cerebral ischemia. As the collateral pathway, ACA collateral and PCA collateral were defined and analyzed. Intraoperative cerebral ischemia was assessed by the continuously monitored electroencephalographic (EEG) change. Internal shunt was inserted routinely. Carotid stump pressure (CSP) was measured through the inserted shunt on all cases. In the cases except for contralateral carotid occlusion (n=100), incomplete pattern on both ACA collateral and PCA collateral was significantly related to the EEG change and CSP≤25 mmHg (p=0.003, p
