It was reported to gore that a 11mm x 10cm gore® viabahn® endoprosthesis was to be implanted for treatment of an iliac artery aneurysm.After the device was advanced to the target lesion, the physician initiated the deployment line and two thirds of the device was deployed.Then a resistance was reportedly felt, the endoprosthesis could not be deployed further.The deployment line was broke when excessive force was used.The distal tip of the endoprosthesis was expanded only 40 percent of the normal diameter.When the physician attempted to retract the catheter, resistance was encountered, the endoprosthesis dislodged and caused an endoleak.The endoprosthesis could not be withdrawn so it was left in patient's vessel.A new gore® viabahn® endoprosthesis of 13mm x 10cm was used to continue the procedure successfully.The device was crushed against the patient's vessel using a 13 x 10 viabahn device.The patient tolerated the procedure.
