The anatomical record : advances in integrative anatomy and evolutionary biology

In this morphological study, we report on the three-dimensional microvascular architecture constituting the toes of a patient affected by diabetic microangiopathy. We applied corrosion casting (CC) technique to the toes of a patient affected by Type 2 diabetes, who underwent surgery for explantation of inferior left limb due to necrotic processes of soft tissues. The toes of a foot traumatically explanted in a motorcycle accident were kept as controls. ⋯ This preliminary report represents only the first step for further investigations regarding morphological three-dimensional appearance of diabetic microangiopathy. CC and scanning electron microscopy technique well documented these morphological modifications, highlighting on both structural and ultrastructural features of diabetic toes microvessels. In conclusion, our qualitative data try to better focus on the pathophysiological mechanisms involved in diabetic dermopathy and microangiopathy, proposing CC as useful method to investigate on them.
