| Research Abstract |
In this research, 82 unruptured cerebral aneurysms were followed with catheter-based 3D rotational angiography, and among them, blister formation was documented in 4 aneurysm during the 10.1 months observation. Three of them could be analyzed here to characterize the hemodynamic features associated with the blister formation. Blister formation occurred at the area of low shear magnitude and high shear gradient. Our findings would contribute to reveal the hemodynamic features leading to the aneurysm progression and provide the basis of the aneurysm treatment via flow alteration.
