The endovascular coiling (EVC) is becoming increasingly popular for treating cerebral aneurysms. Even though EVC has an advantage over conventional surgical clipping, re-treatment is often required within six months. There are several risk factors associated with aneurysm recurrences. Since the aneurysm neck region is highly affected by hemodynamic forces after EVC, studying the influence of local coil packing density at the aneurysm neck volume is valuable for understanding aneurysm recurrence. The present study analyzes the influence of local coil packing density in the anterior communicating artery (AcomA) aneurysm neck volume on the hemodynamics of aneurysm dome volume. A porous medium approach is used to simulate the coil filled inside the aneurysm. From the analysis of flow features (velocity magnitude) and hemodynamic parameters (time-averaged wall shear stress and relative residence time), it was observed that packing density ( \(\text {PD} > 20\) %) in the aneurysm neck volume reduces the chances of aneurysm recurrence.
