It was reported that the coil broke, and there was an unretrieved device fragment.An 8x20 embold fibered detachable coil system was selected for use in the embolization of a splenic artery aneurysm, which was accessed via radial approach.Multiple coils, including non-boston scientific coils and interlock, were used to treat.While positioning the last 8x20 embold fibered, the physician was not satisfied with the final placement of the last 3cm of the coil, and a resistance was felt.Therefore, an attempt was made to retract the coil to better position it, but a resistance was felt.The detachment mechanism was never touched or activated.The coil stretched and likely broke at the coil to coupler weld.Many devices (snares, tulip, and other tools) were used to try and remove the device.Since a snare was able to remove 3/4 of the coil tail, the coil likely broke again somewhere on the length during that snare removal.After two hours, the physician decided to leave the remaining 1/4 of the coil inside the splenic artery and celiac trunk.The patient's status was stable post procedure.There is no plan to remove the fragment at a future date.The patient will be under surveillance.
