A 68-year-old male presented with claudication. His kidney function was impaired. Carbon dioxide angiography revealed the left external iliac artery was occluded. A retrograde approach was attempted from the left CFA. The wire was advanced into the subintimal and failed to re-enter the true lumen. An IVUS catheter was then introduced and positioned near the proximal site of the occlusion. A 0.018-in. wire was advanced with the antegrade approach under the guidance of IVUS image which is located in the false lumen. In this approach, true lumen wiring was achieved. Stenting was performed successfully without injecting any iodinated contrast medium.
一名68岁男性因间歇性跛行就诊。其肾功能受损。二氧化碳血管造影显示左髂外动脉闭塞。尝试从左股总动脉进行逆行入路。导丝进入内膜下但未能重新进入真腔。随后引入血管内超声导管并置于闭塞近端附近。在位于假腔内的血管内超声图像引导下，以顺行入路推进一根0.018英寸的导丝。通过这种方法，成功实现了真腔导丝置入。在未注射任何碘化造影剂的情况下成功进行了支架置入。
