It was reported that the procedure was to treat a lesion located in the left external iliac artery.An 8 x 30 x 135 cm absolute pro vascular stent was deployed in the left external iliac.There were no complications with deployment.The lesion was post dilated with an 8 x 40 balloon, and the balloon was the same length as the stent.The balloon was measured against other 40 mm balloons that had been utilized to prep the lesion, and it was the correct length.Based on this, it was felt that the stent was longer than it¿s labeled length.There was no adverse patient sequela or a clinically significant delay in procedure.No additional information was provided.
