The human aorta endotheliopthy: ultrastructural study in patients treated with BPAC

The ultrastnictural research has emphasized the physiopathology of experi- menta1 and human atherogenesis. The ultrasuuctural study has been carried out on human aorta intraoperatory biopsies of patients subjected to triple by-pass. The endotheiiopathy initially shows a thin endothelial lamina delimited by a iayer of macrophages drawing also residual parietal cells and burst out in the lumen. We have often observed activate platelets trapped in the beneath endothelial area. in the following phase the endothelial lamina stand reciprocally attempting to testore a continuity.
