A 62-year-old man presenting with a small, incidental aneurysm of the anterior communicating artery. A 3D rotational angiogram (A) was obtained before the embolization. Measurements were made of the neck (blue line), diameter parallel to the neck (green line), height (red line), and largest diameter (yellow line). Projection work after a right internal carotid contrast injection (B) shows the relation of the anterior communicating artery aneurysm to the anterior cerebral arteries. Final control after simultaneous contrast injections in the internal carotid artery. C and D, Residual neck flow (white arrow) after stent-assisted coil embolization (stent, white arrows; coils, black arrow). Six-month angiographic controls (E and F) show the evolution to complete occlusion (black and white arrows).

Results of the Pearson test, demonstrating that above 19% packing density, all aneurysms had complete occlusion. Regarding the volume, aneurysms above 179.6 mm3 had a higher rate of incomplete occlusion when the packing density was below 19%. If >1 aneurysm is overlapping, note the following symbols:
, 2 aneurysms, , 3 aneurysms, , 4 aneurysms.
