It was reported that balloon rupture occurred.Vascular access was obtained via femoral artery using a 7f non-bsc introducer sheath.The 75% stenosed target lesion was located in the severely tortuous and moderately calcified both common iliac artery (cia) and external iliac artery (eia).A non-bsc guidewire crossed the lesion in the opposite side to the right and after ivus in eia, pre-dilatation was performed using the 4x40 non-bsc balloon catheter.After the 8x100 epic stent was placed on the eia, post dilatation was performed using a 5x100 sterling balloon catheter but remaining residual stenosis was noted.The device was replaced with a 7.0mmx40mmx135cm sterling balloon catheter.However, within specified pressure, the balloon ruptured.A 6x40 sterling balloon catheter was used and completed the post dilation.After placing the 8x100 epic stent on the left side of cia, post-dilation was performed with a 9.0 x 40, 75cm mustang balloon but failed to cross the lesion.A new 8x40 mustang balloon was used to complete the procedure.There were no patient complications were reported.
