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.
在某些临界肢体缺血 (CLI) 患者中，若正向再通失败，应考虑逆行或联合逆行和正向再通。逆行再通通常通过腘动脉或腘下动脉的一段通畅段进行尝试。然而，当没有适合逆行入路的通畅腘动脉或腘下动脉时，就会出现挑战。
