It was reported that 19 days post deployment of two lvis stents for the treatment of a ruptured aneurysm in the internal carotid artery, the aneurysm became slightly enlarged and the patient had to be retreated with an additional lvis blue stent.During removal of the delivery wire, however, it became caught in the area where the stent was implanted.The physician was able to remove the wire by raising the microcatheter and applying force.After detachment, the cone-beam ct revealed that the tip of the delivery wire had most likely broken off and remained in the patient.An additional lvis blue stent was implanted from c1 to c4 to affix the tip of the wire to the vessel wall.The procedure was successfully completed and the patient condition was reported as "non-serious health damage".
