      A case of severely calcified neoatherosclerosis-embedded stent struts clearly documented with optical coherence tomography imaging

      A 65-year-old Japanese man using peritoneal hemodialysis due to diabetic nephropathy underwent a planned coronary angiography as a preoperative examination. Fourteen years earlier, he had undergone a percutaneous coronary intervention due to acute myocardial infarction and had been implanted with a bare-metal stent in the left anterior descending coronary artery. Although his condition had run a benign course without any recurrence of cardiovascular events, coronary angiography was performed 14 years later in preparation for a living-donor kidney transplantation. Coronary angiography revealed less than 50% restenosis (Figure A). Although Figure B indicates circumferentially covered stent struts, the homogeneous neointima pattern observed ...

    2. Optical Coherence Tomography Angiography: A New Vision Into The Future of Retinal Imaging

      Optical Coherence Tomography Angiography: A New Vision Into The Future of Retinal Imaging

      Optical coherence tomography angiography (OCTA) is a brand new imaging tool developed and clinically introduced recently into the ophthalmological diagnostic tool armamentarium. OCTA enables a segmented and detailed examination of retinal vasculature and structure in a non-invasive fashion within a few seconds based on the present and widespread OCT technology. Retinal and glaucoma specialists can evaluate vascular circulation in every possible separate layer for the first time in ocular imagining history and acquire a new understanding in the pathological process of ophthalmological diseases using OCTA. The developing process of this innovative technology is still in progress by companies based on ...
