Challenging of contrast agent-free endovascular treatment using 3D imaging

With advances in devices and techniques, the success rates of percutaneous coronary intervention(PCI)and endovascular treatment (EVT)remarkablly increased. This increased success has facilitated the pursuit of less invasive procedures, such lower dose of contrast agent, lower exposure, and shorter procedure time. Taking advantage of intravascular imaging techniques such as intravascular ultrasound(IVUS)and optical coherence tomography (OCT)/optical frequency domain imaging(OFDI), we are tring to perform accurate and less invasive procedure. When considering less invasive precedures, the role of the angiographic apparatus is significant. With regard to EVT for peripheral arterial disease, in particular, we suggest that the Trinias(Shimadzu Corporation)with the SCORE Navi+Plus is very useful.
