It was reported that there was a leak, difficulty removing the device, and unretrieved device fragments left in the patient.A 12mm x 60mm x 75cm charger balloon catheter was selected for use in a left upper arm balloon angioplasty and stenting procedure.The left upper subclavian vein had two previously placed stents.One stent appeared to have been placed through the struts of the other.Some fractures were present with exposed nitinol struts.Upon inflation and deflation in the area of the fractured stent, blood was noted in the inflation device, which indicated a pin hole or tear in the balloon material.Resistance was felt upon removal.Some balloon material remained on the stent strut.A second wire was placed next to the first and used to complete the case.A 12mm x 60mm venous wallstent was placed over the second wire and post dilated with a 10mm x 40mm balloon, which opened the in-stent restenosis and trapped any balloon material behind the stent.Angiographic and intravascular ultrasound (ivus) imaging proved to be widely patent.Both the first and second wires were removed without incident.
