We present the 6-month anatomic, histological, and immunohistochemical (IHC) images of a diffuse and aggressive type of in-stent restenosis of a popliteal artery of a patient homozygous for the D (deletion) allele of the ACE gene (Figures 1⇓, 2⇓, and 3⇓).A detailed description of the histological changes of the arterial wall with time after coronary stenting in humans was published recently.1 These findings have confirmed that the ultrasound-detected “neointima” observed >1 month after implantation is composed primarily of smooth muscle cells (SMCs) and a proteoglycan-rich matrix. In the first weeks after stenting, …
