“…It may be difficult to deliver this catheter through severely rugged lesions. Angioscopic imaging is reported to be useful for the diagnosis of vascular thrombus, plaque behavior, and stent strut neointimal coverage in peripheral artery disease [6], [7], [8]. This is the first report on the clinical use of Zemporshe.…”

A 47-year-old female patient was admitted with a complaint of severe chest pain on effort. She had a history of effort angina treated using coronary artery bypass with left internal thoracic arterial bypass to the left ascending coronary artery. She also had left subclavian and vertebral arterial stenoses, which were treated with balloon-expandable stents. Exercise stress myocardial perfusion imaging revealed anterior to apex left ventricular myocardial ischemia. Cardiac ischemia due to left subclavian stenosis was diagnosed. We treated the left subclavian arterial stenosis with endovascular therapy. We observed that the vertebral Palmaz stent protruded from the ostium and the jailed subclavian artery on high-resolution angioscopy (Zemporshe with a 0.48-megapixel equivalent resolution; Taisho Biomed Instruments, Osaka, Japan) and optical frequency domain imaging (OFDI). A guide wire was successfully crossed through the Palmaz stent strut, which was confirmed using three-dimensional OFDI. The stent strut was dilated using balloon angioplasty. New imaging technologies are promising tools for improving the efficacy and safety of craniocervical intervention.

“…On the other hand, recently, it has been reported that angioscopy, which was usually used for evaluation of coronary arterial healing following stenting, [1][2][3][4] could be applied to evaluate the characterization of inside the vessel during and after endovascular therapy (EVT) including stent implantation in the femoropopliteal lesions. [5][6][7] Angioscopy can directly visualize the grade in the femoropopliteal lesions. Therefore, we report 2 cases who showed direct visualization of effect of ELA for femoropopliteal ISR lesions using angioscopy.…”

In-stent restenosis (ISR) is a prevalent problem following stenting of femoropopliteal lesions. A potential novel treatment modality for ISR including excimer laser atherectomy (ELA) has become available. We performed ELA for in-stent chronic total occlusion (CTO) of femoropopliteal lesions and evaluated lesion morphology before and after ELA by angioscopy in 2 patients. The angioscopic findings clearly showed removal of in-stent thrombi after ELA. Thus, ELA may be effective for in-stent CTO of femoropopliteal lesions. This is the first report describing the direct visualization of ELA effect for vaporization of thrombi in femoropopliteal in-stent lesions by angioscopy.
