We saw a huge hematoma under the posterior peritoneum, and a large amount of blood flowed out from the rupture of the posterior peritoneum.The surgeons quickly opened the posterior peritoneum and located the source of the massive bleeding: an abdominal aortic bifurcation rupture, approximately 5 cm in length an severely lacerated with a thin and irregular rupture wall, was found (Figure 1).
