Hemodynamics of intentional partial endovascular coil filling in a wide neck middle cerebral artery aneurysm

The endovascular coiling (EVC) is becoming increasingly popular for treating cerebral aneurysms. Even though EVC has an advantage over conventional surgical clipping, wide neck aneurysms (WNAs) are difficult to treat with EVC. Coil migration into the parent vessel leading to iatrogenic stroke, is a major cause for concern in treating WNAs. Despite the fact that stent-assisted coiling is effective in the treatment of WNAs, due to the high rate of complications, it is not preferred for ruptured aneurysms [1]. However, intentional partial coiling of an aneurysm at the rupture point reduces the risk of the early re-bleeding. This can be followed up with a surgical clipping or stent-assisted coiling at a later time. It is difficult to predict the ruptured region of an aneurysm and the coil fill volume needed to stop early re-bleeding before the aneurysm rupture. To this end, the present study investigates the critical rupture portion of an aneurysm and the partial aneurysm volume required to fill by the embolic coil to stop early re-bleeding for a patient-specific middle cerebral artery aneurysm having a wide neck.
