Event Description

It was reported that the stent was difficult to position and stent migration occurred.A 14x120mm, 100cm and a 16x60mm, 100cm vici stent system were selected for use in a procedure on (b)(6) 2021.The patient presented with compression of the left common iliac vein (lciv) and stenosis of the left external iliac vein (leiv) upon obtaining intravascular ultrasound (ivus) images.The reference external iliac vein (eiv) averaged 13mm.The eiv was measured because there was not a place within the confluence that was able to be measured.A 14x120mm vici stent was placed from the common iliac vein (civ) to the distal eiv.Upon deployment, the stent dropped below the civ compression due to the severity of the compression.Only 2cm of the stent was in the confluence.A 16x60mm vici stent was placed above the 14x120mm stent with approximately a 2-3cm overlap into the 14x120mm stent.The stents were post-dilated with a balloon.Ivus images were obtained showing complete apposition to the vein walls.On (b)(6) 2021, the patient went to the emergency department with heart fluttering and shortness of breath.Images were obtained that showed both vici stents had migrated to the right atrium as a unit.The patient was stable and awaiting surgery to remove the vici stents.On (b)(6) 2021, the stents were surgically removed.Post surgery, the patient's chest tubes were removed.The patient was stable and doing well.
