Effect of Neck Size on the Inflow Magnitude Evaluated on 4D Flow MRI in Unruptured Internal Carotid Artery Aneurysms

Endovascular coil embolization for cerebral aneurysms is widely performed to prevent hemorrhage or rebleeding, and it has low morbidity and mortality. However, recanalization which frequently arises during the follow-up period after coil embolization and occasionally leads to a catastrophic rupture remains a major limitation. A recanalization rate of 8.6 –27.4% has been reported in recent systematic reviews of studies that analyzed several thousands of cerebral aneurysms.1–3 A wide neck of aneurysms has been a key factor for recanalization.
