“…1,[51][52][53] In the present study, abnormalities suggestive of EHBTO were found in all 21 cats that underwent ultrasonography. Because chronic biliary obstruction can itself result in irreversible inflammatory and fibrotic changes, 48-50 more timely diagnosis of EHBTO might improve the clinical outcome in affected cats.…”

“…5 The literature describing ultrasonographic changes to the CBD in non-obstructive processes reports less severe CBD dilatation. In a population of cats with surgical or necropsy-confirmed non-obstructive hyperbilirubinemia, maximal CBD diameter did not differ significantly from normal cats, 4 and in cats with cholangitis or liver fluke infestation CBD dilatation to or beyond 5 mm was not reported in conjunction with a patent biliary tract. 9,14,15 …”

“…1,2 The remaining components of the biliary tree (extrahepatic ducts and intrahepatic structures, including interlobular ducts, interlobar ducts and larger hepatic bile ducts) are not ultrasonographically visible unless there is pathological dilatation. 1,2,4 In the cat, a CBD diameter of up to 4 mm is considered normal. 2,4,5 …”

Case series summaryThis case series documents ultrasonographic and clinicopathologic features of four cats with marked segmental dilatations of the common bile duct (CBD). All cats had additional ultrasonographic changes to the hepatobiliary system, including hepatomegaly, tubular to saccular intra/extrahepatic biliary duct dilatation and biliary debris accumulation. Based on all available data the presence of extrahepatic biliary duct obstruction (EHBDO) was ruled out in 3/4 cases and was equivocal in one case. One cat underwent re-routing surgery to address the CBD dilatation after multiple recurrent infections, one cat was euthanized and had a post-mortem examination and two cats were medically managed with antibiotics, liver protectants, gastroprotectants and cholerectics.Relevance and novel informationThe ultrasonographic features of the CBD in this population of cats were supportive of choledochal cysts (CCs). The maximal diameter of the CBD dilatations exceeded 5 mm in all cases, a sign that has been previously reported to be consistent with EHBDO. In our study, dilatations were segmental rather than diffuse. Given the high morbidity and mortality associated with hepatobiliary surgery in cats, segmental dilatation of the CBD should not prompt emergency surgery. Some cats may respond to medical management. Careful planning for cyst resection was beneficial in one cat. Evaluation of CC morphology (eg, size, location, concurrent intrahepatic anomalies) may assist in selecting cats that could benefit from surgical intervention.

“…A vesícula biliar preservou caracterís-ticas conforme citações entre as espécies domésticas . Apresentou-se sempre repleta e com conteúdo anecói-co, não demonstrando assim, indícios de doença do sistema biliar, bastante comum nas visualizações da vesícula biliar para algumas espécies primatas (Pissinatti et al 1992), carnívoros (Léveillé et al 1996) e mesmo no homem (Shea et al 1994, Pandey et al 1996, Petroni et al 2000.…”

O macaco-prego, Cebus apella, é muito difundido no norte e sul da Amazônia Legal Brasileira e no Cerrado. Estes animais encontram-se rotineiramente submetidos à caça predatória, aumentando assim a necessidade de preservação desta espécie silvestre. Realizou-se um estudo ultra-sonográfico de 10 macacos-prego como forma de descrever a anatomia ultra-sonográfica normal de sua cavidade abdominal. A vesícula urinária apresentou parede com espessura média 0,2cm e em posição anatômica cuja topografia permitiu contato com as paredes do corpo do útero e cólon descendente. À varredura abdominal caudal foi visualizada a aorta, veia cava caudal e veia ilíaca direita. O fígado foi visto em varredura sagital e transversal, possibilitando a observação da vesícula biliar e vasos hepáticos. A varredura renal demonstrou com precisão a pelve, seio renal e relação cortico-medular. O comprimento médio de ambos os rins foi de 6,24±0,31cm, não existindo diferença estatística entre o rim direito e esquerdo (Teste t de Student e ANOVA). O volume renal foi 2,37±0,18cm³. Os coeficientes de Correlação de Pearson entre os comprimentos renais direito e esquerdo e entre volumes renais direito e esquerdo foram dispostos como r = 0,74 e 0,51. As espessuras médias para a região cortical e medular foram 0,75±0,11cm e 0,39±0,06cm, respectivamente. O coeficiente de correlação para a relação cortico-medular entre os rins direito e esquerdo foi de r = 0,19. O exame ultrasonográfico mostrou-se como uma técnica eficiente, nãoinvasiva, rápida e reprodutível, que provê dados importantes aos profissionais da área de clínica e cirurgia de animais silvestres.
