    The macro and microscopic alterations that occurred in the spleen during an ischemia produced by the hepatic pedicle total clamping were studied. Forty male rats were distributed in four groups of 10 animals each. The control group (C) was not submitted to ischemia and the treated groups (E1, E2, and E3) were submitted to the clamping during 10, 20, and 30 minutes, respectively. Spleen fragments were collected and histologically analyzed by the light microscopy (eosin-hematoxilin and ferric ferrocyanide) and by the transmission electron microscopy. The results showed that 10 minutes of hepatic pedicle total clamping was enough produce signs of splenic congestion and 20 and 30 minutes promoted intense red bood cels digestion by the macrophages with the presence of iron granules (hemosiderin) in the splenic parenchyma.
