Resumo: One of the complications of hepatic pedicle total clamping is the splanchnic congestion and consequently a splenic congestion. The aim of this study was to evaluate the macro and microscopic alterations that occurred in the spleen during an ischemia produced by the hepatic pedicle total clamping. Fourthy male rats were divided in four groups of ten animals each. The control group (C) was not submitted to ischemia and the experimental groups (E1, E2 and E3) were submitted to the clamping during 10, 20 and 30 minutes, respectively. After these periods, spleen fragments were collected and histological analyzed by the eosin-hematoxilin and ferric ferrocyanide staining technique. Based on the results it is possible to conclude that 10 minutes of hepatic pedicle total clamping is sufficient to show signs of splenic congestion and 20 and 30 minutes promote intense red bood cels digestion by the macrophages with the presence of iron granules (hemosiderin) at the splenic parenchyma.

Este trabalho teve como objetivo avaliar as alterações morfológicas, morfométricas e ultra-estruturais que ocorreram no baço frente à isquemia produzida pelo clampeamento total do pedículo hepático. Para tanto foram utilizados 40 ratos machos, divididos em quatro grupos de 10 animais. O grupo controle (C) não foi submetido à isquemia, já os grupos experimentais (E1, E2 e E3) foram submetidos ao clampeamento por 10, 20 e 30 minutos, respectivamente. Após esses períodos, fragmentos do baço foram retirados e analisados histologicamente pela técnica de Hematoxilina-Eosina, Ferrocianeto-Férrico e microscopia eletrônica de transmissão. Os resultados mostraram alterações microscópicas nos grupos E1, E2 e E3 que permitem concluir que 10 minutos de clampeamento do pedículo hepático são suficiente para apresentar sinais de congestão esplênica e 20 e 30 minutos promovem intensa digestão de hemácias pelos macrófagos, com presença de grânulos de ferro (hemossiderina) no parênquima esplênico.Submitted by (edna.saturno@ufrpe.br) on 2016-11-03T15:18:19Z No. of bitstreams: 1 Silvio Henrique de Freitas.pdf: 2884421 bytes, checksum: 0b351af124c9eb712468443a25a94991 (MD5)Made available in DSpace on 2016-11-03T15:18:19Z (GMT).
