Endovascular therapy (EVT) was performed in two cases with chronic total occlusion (CTO) of superficial femoral artery. In these cases, angioscopy was deployed in the backyard of the CTO lesion from popliteal artery retrogradely, then the guidewire was advanced from antegrade. When the wire crossed the distal of the CTO lesion, the wire penetration was clearly visualized by the retrograde-angioscopy. Therefore, wire crossing of CTO into the distal true lumen was certainly confirmed, and EVT was successful. < Angioscopy-guided endovascular therapy for chronic total occlusion was useful not only to evaluate thrombus and plaque in situ visually, but also to successfully perform guidewire crossing.>.
对两例股浅动脉慢性完全闭塞（CTO）患者进行了血管内治疗（EVT）。在这些病例中，从腘动脉逆行在CTO病变的远心端进行血管内镜检查，然后从顺行方向推进导丝。当导丝穿过CTO病变的远端时，通过逆行血管内镜可以清晰地看到导丝的穿透情况。因此，肯定证实了CTO的导丝穿过进入远端真腔，并且EVT成功。<血管内镜引导下的慢性完全闭塞血管内治疗不仅有助于直观地原位评估血栓和斑块，还有助于成功完成导丝穿过。>
