title: Case report: an unusual combined retrograde and antegrade transpedal subintimal recanalization of the infrainguinal arteries.
abstract: Retrograde or combined retrograde and antegrade recanalization should be considered when antegrade recanalization has failed in selected patients with critical limb ischemia (CLI). Retrograde recanalization is typically attempted through a patent segment of the popliteal artery or an infrapopliteal artery. The challenge arises, however, when there are no patent popliteal or infrapopliteal arteries suitable for retrograde access.
