It was reported that stent foreshortening occurred.The severely stenosed, 30-40mm target lesion was located in iliac vein.After the guidewire was inserted and pre-dilation was performed, a 14x90/9fr uni plus 75cm wallstent endoprosthesis was advanced for treatment.However, during deployment, the proximal of the stent was shrinked at 1-1.5cm.The lesion was overlapped with another 16x90/9fr uni plus 75cm wallstent endoprosthesis stent and pre-dilated again with balloon catheter.The vessel monorlogy was good but the proximal part of second stent was also shrinked at about 2cm, which affected the positioning.A balloon was used to push the stent ahead at the opening.The procedure was completed with another of the same device.There were no patient complications reported and the patient was stable.
