The authors report the case of a patient who, 20 months after carotid TEA including the application of a bovine pericardium patch, presented a swelling with cutaneous erosion above the previous surgical wound. The patch was removed surgically. The internal carotid was replaced by inverted saphenous vein and the external carotid was ligated. In macroscopic terms the patch presented a fistulised central erosion on the overlying cutaneous layer. Culture tests were positive for Staphylococcus epidermidis. Histological tests showed the presence of major hemorrhagic phlogosis. Ultrastructural tests confirmed the marked presence of mixed inflammatory infiltrate, but no pathogenic microorganisms were observed. The scant number of cases in which this type of patch has been used precludes any conclusions being drawn regarding the predisposition of this material to infection. However, the complication described here confirms the need for a closer follow-up of these patients.
