Retrograde approach to recanalization of complex tibial disease.

A significant proportion (~ 20%) of patients with complex tibial artery occlusions cannot be treated using a conventional antegrade approach. We report our experience using the retrograde approach for the treatment of complex tibial artery occlusive disease using retrograde pedal/tibial access in 13 limbs from 12 patients. Retrograde pedal/tibial access was achieved in all cases (facilitated by surgical cutdown in one case), and procedural success was achieved in 11 of 13 limbs (85%). Based on this experience, a discussion of clinical and technical aspects of the retrograde pedal/tibial approach is provided, and a new classification for tibial artery occlusive disease is proposed.
