The usual aerobic and anaerobic smears and cultures were performed, but were not revealing. The first time, surgical management was carried out as if sepsis was not present, but hemorrhage recurred. Revision of the reconstruction was then performed using extra-anatomic principles to avoid infected tissue via the obturator bypass technique.1 Four weeks later, hemorrhage occurred
