A ultraverse 2.0 was attempted to be inflated but could not cross.Then a ultraverse 1.25 could not cross either.The device crossed with difficulty and was inflated at 18 atm for 20 seconds.A ultraverse 2.0 was additionally inflated at 14 atm for 150 seconds with no vessel perforation.Then ata ostial and mid site was additionally treated after crossed by gladius.The device crossed the ata ostial with difficulty and the parent plus 3 fr 58 cm was managed to be advanced to bk3 bifurcation and inflated at 12 atm for 60 seconds.Subsequently the ata mid side could not be crossed so the parent plus 3 fr 58 cm was delivered to around the ata ostial and the device was advanced with difficulty and inflated at 12 atm for 60 seconds.Just after that it was found the device got looped at around the bk bifurcation and removed outside the body.At the same time the patient's blood pressure decreased and the patient expressed severe pain so angiography was performed and at pop-bk (3-bifurcation) vessel perforation was confirmed.A sterling 4.0/40 mm was inflated at 12 atm for 1,140 seconds to stop bleeding but could not so the patient transferred to the surgery division to perform angiorrhaphy.No cine was provided.The physician's comment: when the ata mid side was treated the parent plus 3 fr 58 cm was pushed back to around pop when the jade was strongly pushed, which might have made the jade got looped.Pop-bk, 100 % stenosed, heavily calcified, slightly tortured, elective pta, ipsilateral approach; the device was not returned for investigation; the lesion was crossed using a parent plus 3 fr 58 cm, teleport and gladius.
