HOW TO CROSS VERY HUGE CALCIFICATIONS in SFA TOTAL OCCLUSION? The answer is GoBack (not to school but GoBack Crossing catheter) when all else fails; enables keeping in the lumen. Ex.: CTO left SFA calcified all over , Grade 4 PACSS score (Rocha-Singh et al); antegrade femoral approche, 6F sheath, 3000 IU Heparine; ALL devices failed to cross; GoBack in the lumen, prep artery by “step to step” ballons and finally SUPERA stents (of course).
