Background• Transradial access for BTK lesions
• Technically possible, but only in limited cases due to short delivery systems
• Transpedal access for BTK lesions• Potential advantage
• It needs a short delivery system
• Less access site complications at the femoral access site
• Excellent pushability
• Immediate mobilisation
• Potential disadvantage• Target or donor artery occlusion
• Less techniques are available than during anterograde access for example plantar archreconstruction
• Retro only strategy has many limitations and anterograde GW advancement is necessaryin many cases

Aim of the study
• To assess the feasibility of the TR and TP approach in isolated BTK disease in CLI
• To investigate the clinical success rate angioplasty
• To investigate the complication rate of the TP access in BTK disease
![Page 8: E-poster12 Ruzsa aimradial20170922 Retrograde transpedal](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6497337f8b9a5d568b4cfd/html5/thumbnails/8.jpg)
Methods• 19 consecutive patiens with CLI
• Study design• Prospective pilot study
• Inclusion criteria• Critical limb ischemia on the lower limb (Rutherford IV-VI)
• Isolated below-the-knee stenosis or occlusion (more than 70%) and viable limb
• Exclusion ctiteria• Non viable lower limb
• At least one BTK artery with good distal run-off
• Infected puncture site
• End-points• Technical success

Can we perform BTK stenting from TR and TP access ???
