Event or Problem Description
As reported by the field, this was a coil embolization to a left anterior communicating artery aneurysm (acomm) with high tortuosity.The physician attempted to coil aneurysm initially with only coils.First coil was a uniform 7mm x 30 cm (fcx100730, 31127140).This specific aneurysm had a ledge towards the neck of the aneurysm that caused a headway duo 156cm microcatheter (mc) to become unstable.Because of the ledge, because of the force needed to advance the coil into the aneurysm, the coil fractured at the junction of the coil and the pusher wire.The 5 fr sofia was advanced and the coil was taken out with the microcatheter as a unit.The entire coil was removed.New microcatheter was used to re-access the aneurysm.The second coil, a uniform 7mm x 13.9 cm (fcx100713, 31098464) was advanced into the aneurysm without any issue.Attempted to detach coil with mechanical detachment handle (mdh1, 102109430) unsuccessfully.The manual break was used correctly and that was unsuccessful as well.That coil was removed without any issues.A micrusphere xl 7mmx14cm coil (ssr10071420, 30529251) was used at this point with the same microcatheter in place.That coil fractured as well due to the ledge of the aneurysm as described before.That coil was removed as a system also with the same technique used for the first coil.Balt coils were used for the rest of this case without any issues.The fracturing of these coils did cause delay in case about 30 minutes.No negative impact to patient was reported.
