The following information was obtained at the 14th (b)(6) endovascular symposium: on an unknown date, the patient underwent endovascular treatment using two non-gore stent graft (graftmaster 2.8 x 16 mm, 3.5 x 16 mm) for right posterior tibial pseudoaneurysm.During the procedure, a proximal type i endoleak of non-gore stent graft was observed.To treat the endoleak, a gore® viabahn® endoprosthesis (5.0 x 25 mm) was deployed proximally.Then, the stent graft did not fully open, and stuck on the leading olive.The physician was unable to remove the delivery catheter.The physician attempted to remove the delivery catheter using a balloon anchor, however it was unsuccessful.The physician fixated the stent using a guide wire and the delivery catheter was removed.An additional stent graft was deployed on the proximal side.The final angiography showed blood flow distally and the aneurysm diameter tended to decrease.The patient tolerated the procedure.On an unknown date, five months after the initial procedure, it was noted that the stent grafts were occluded.The physician is monitoring the patient.The physician stated: an oversized stent graft was selected.(the blood vessel diameter unknown).The ballooning before the deployment was insufficient.The physician understood the site was outside of ifu, but it was an emergency procedure.
