Coil embolization of recurrent ruptured vertebral artery dissection through a marathon microcatheter: A case report.

ABSTRACT: A 56-year-old healthy woman presented with subarachnoid hemorrhage caused by ruptured vertebral artery dissecting aneurysm and was treated with internal trapping of the affected site including the aneurysm. She suffered rebleeding due to recanalization of the aneurysm 5 days after the first treatment. Because of the close proximity of the coil mass to the posterior inferior cerebellar artery (PICA) origin at first treatment, additional coil embolization by tight packing of the coil mass was planned. However, navigation of the microcatheter into the coil mass was challenging due to the tightly packed coil mass. Thus, a Marathon microcatheter, which has narrower outer diameter and is designed for liquid embolization, was used and successfully placed into the coil mass in an anterograde fashi
