The patient was undergoing a coil embolization procedure in the gastroduodenal artery (gda) using a pod coil, pod packing coils (pod pc), and a lantern delivery microcatheter (lantern).During the procedure, the physician successfully implanted a pod coil and three pod pcs in the target vessel using the lantern.Subsequently, after performing a final angiogram, the physician noticed the last pod pc migrated into the main artery.Therefore, the physician used a snare device to retrieve a portion of the pod pc out of the patient.It was also reported the pod pc unwound while snaring the coil and a portion of it remained in the gda.The procedure was completed at this point.There was no report of an adverse effect to the patient.
