A guidewire can be externalized after retrograde lesion crossing. Wire externalization provides excellent support for ballooning and stenting and for the treatment of chronic total occlusion lesions that are long calcified, tortuous, and difficult to treat. This review discusses the final steps of the retrograde technique via wire externalization, stenting, and wire removal.
逆行穿过病变后可将导丝引出体外。导丝引出体外可为球囊扩张和支架置入以及治疗长段钙化、迂曲且难以治疗的慢性完全闭塞病变提供极佳的支撑。本文综述了通过导丝引出体外、支架置入和导丝移除的逆行技术的最后步骤。
