“…The congestion index also significantly increased 3 days after ligation and thereafter Total hepatic perfusion and the relative contributions of the hepatic arterial and portal venous systems can be altered by a variety of liver diseases. These include diffuse hepatocellular disease, neoplasia, and portovascular shunts which can markedly affect hepatic circulation [12][13][14].…”

ABSTRACT. Portal blood flow was measured using pulsed Doppler ultrasound in 6 dogs before and after left portal vein branch ligation. Mean portal vein blood flow velocity and mean portal vein blood flow were significantly reduced after ligation and the congestion index was increased (p<0.01). Pulsed Doppler ultrasound studies provide valuable physiological information which may assist the clinician with the diagnosis of canine hepatic circulatory disorders.-KEY WORDS: canine, Doppler ultrasound, portal blood flow.

“…Notou-se a precocidade da ultrassonografia na detecção de alterações em parênquima hepático, mesmo na ausência de mudanças em exames bioquímicos, concordando com relatos descritos por Nyland et al (1989) e Mamprim et al (1997. Desta forma, pode-se reafirmar que a ultrassonografia é uma ferramenta essencial para identificar anormalidades no parênquima hepático e trato biliar (Cartee 1981, Lamb 1990, Biller, et al 1992, Barr 1995, Selcer 1995, Feeney et al 2008.…”

“…A ultrassonografia, ferramenta essencial para identificar anormalidades no parênquima hepático, trato biliar e sistema vascular (Cartee 1981, Lamb 1990, Biller et al 1992, Barr 1995, Selcer 1995, Feeney et al 2008, é capaz de acrescentar informações diagnósticas antes mesmo de serem observadas alterações em exames bioquímicos e em radiografias convencionais (Nyland et al 1989, Mamprim et al 1997, Kanemoto et al 2013. Isso se deve ao fato de que 70% ou mais da capacidade funcional do fígado deve estar comprometida para que haja manifestações clí-nicas e alterações nas atividades séricas das enzimas hepá-ticas (Dial 1995, Tennant 1997.…”

Pesq. Vet. Bras. 33(Supl.1):85-92, dezembro 2013 85 RESUMO.-No presente estudo foi analisado o parênquima hepático com características homogêneas e ecogenicidade difusa reduzida (G1), aumentada (G2) e normal (G3), em relação ao perfil dos animais, dimensão do fígado e achado bioquímico e hematológico. Amostras de sangue obtidas por punção venosa da jugular ou da cefálica do antebraço foram encaminhadas para realização de hemograma e dosagem sérica de ALT, FA, proteínas totais, albumina, globulina, uréia e creatinina. The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.

“…Focal hypoechoic regions in the spleen can be another pattern visualized secondary to lymphoma or infarction. 10 Ultrasonography of splenic hemangiosarcoma has variable echo patterns (anechoic to hyperechoic). 11 Hematomas (<5 cm) are usually hypoechoic to anechoic, whereas large ones (>6 cm) contain a mixture of anechoic, hypoechoic, hyperechoic, and isoechoic material.…”
