As reported, the 8mm x 59mm x 80cm palmaz genesis transhepatic biliary stent on.035¿ opta pro percutaneous transluminal angioplasty (pta) delivery system dislodged from the balloon inside the patient.The patient was fine, but they had to use another unknown stent.The left iliac artery was pre dilated with a powerflex 5 x 40 at 10 atmospheres (atm).They crossed the area with a 9 x 39 genesis with no issues prior to placing the 8 x 59.The patient had a medical history of peripheral vascular disease.The intended procedure/target lesion was the iliac artery.Vessel / lesion characteristics, the lesion had little calcification.The vessel had little tortuosity.The vessel had no angulation.The device was not used for a chronic total occlusion (total occlusion >3 months).The device was not resterilized.There were no anomalies noted when removed from the package.There were no anomalies noted during prep.The device was not inserted through a stopcock instead of a hemostatic valve.The segment was left i the iliac artery.The patient is stable after the event.The device will not be returned as it remained in the patient.
