↵* Immediate angiographic results are graded based on contrast stasis within the aneurysm. Mild stasis is defined as contrast visualized in the aneurysm until the late arterial phase. Moderate stasis is defined as contrast visualized in the aneurysm until the capillary phase. Pronounced stasis is defined as contrast visualized in the aneurysm until the venous phase.
