Ultra-sonografia do fígado, aparelho renal e reprodutivo da jibóia (Boa constrictor)

Abstract

RESUMO.-Atualmente os animais silvestres têm despertado o interesse particular na criação domestica. Na medicina de animais selvagens, os exames ultra-sonográficos podem ser considerados como ferramenta para diagnosticar e prevenir doenças. Deste modo, realizou-se um estudo em 20 jibóias (Boa constrictor), a fim de caracterizar a morfologia e aparência ultra-sonográfica das estruturas presentes da cavidade celomática desses animais. Ultra-sonograficamente, o fígado apresentou-se variando de hipoecóica a levemente hiperecogênica, com margens ecogênicas e ecotextura homogênea em toda sua extensão. Os rins mostraram formato elipsóide, com cápsula fina, regular e hiperecóica. Os folículos ovarianos apresentaram formato ovóide, margens finas, regulares e discretamente hiperecóicas. As estruturas do sistema reprodutor do macho não foram evidenciadas com precisão, devido a sua ecogenicidade similar em relação às Currently, wild animals have been received special attention for domestic breeding. In Wild Animal Medicine, ultrasonographic exams could be considered as a tool to diagnose and prevent disease. Ultrasonographic examination of twenty snakes (Boa constrictor) was performed in order to describe the morphological and ultrasonography appearance of their coelomic structures. Examination by ultrasonography revealed the parechymal liver ranging from slightly hypoechogenic to hyperechogenic, with echogenic margins and homogeneous echotexture in total scanning of this organ. The kidney was accessible for examination by sagittal ultrasound, showing an ellipsoid shape, a hyperechogenic capsule with a thin and regular wall. Ultrasonographic scanning of ovarian follicle showed an ovoid shape, as well as a thin, regular and slightly hyperechogenic edge. No evident structures from male reproductive system were identified by ultrasound examination because of their similar echogenic appearance to the tissues around and the "body fat" that lies in this region. Examination by ultrasound of the coelomic structures was a fast and repeatable technique, which provides useful data to recognize the morphology, sintopy and ultrasonographic appearance of organs such as liver, kidneys and vitellogenic follicles.INDEX TERMS: Boa constrictor snake, ultrasound, wild animals, Amazon.

Hormonal and ultrasonographic characterization of the seasonal reproductive cycle of male and female Crotalus durissus terrificus

“…Chemical restraint can be indicated for aggressive or very active snakes for ultrasound exams (Betkowski, 2006;Chiaraviglio et al, 1998;Gnudi et al, 2009), though snake retention only with a plastic tube in our study was efficient for testicles visualization by ultrasound. Testicular topography observed is consistent with reported in another studies (Chiaraviglio et al, 1998;Neto et al, 2009;Redrobe and Wilkinson, 2002). Despite this, one testis in some males was not found, which may have occurred due to air accumulation between scales during ecdysis and the presence of gas and feces in intestine (Isaza et al, 1993;Raiti, 2000), producing reverberation artifacts.…”

“…The morphology and testicular echotexture found were similar to those described in literature (Chiaraviglio et al, 1998;Neto et al, 2009;Redrobe and Wilkinson, 2002). Echotexture testes did not suffer seasonal influence, but greater sizes were found closer to the breeding season (summer).…”

In some snakes, fat in coelomic cavity hindered testes location because of the similar echogenicity, as described in other species (Isaza et al, 1993;Neto et al, 2009;Raiti, 2000).…”

Anatomia ultrassonográfica de fígado, baço e trato urogenital em jiboias

“…Os avanços alcançados na Medicina de Animais Selvagens têm possibilitado uma extensa gama de exames complementares necessários para subsidiar estudos clínicos e cirúrgicos na Medicina de Répteis. Neste sentido, o exame ultrassonográfico é de suma importância, pois auxilia na terapêutica e minimiza a possibilidade de manobras invasivas desnecessárias (NAVARRE, 2006;NETO et al, 2009;ANDRADE, 2010) O diagnóstico ultrassonográfico na clínica de répteis constitui uma inovação, sendo utilizado com a finalidade de identificar diferenças anatômicas. Além disso, difere de outros métodos de diagnóstico por ser livre de qualquer efeito ionizante, ou seja, não promove alterações físico-químicas intracelulares pela transferência de energia aos átomos e moléculas presentes no campo irradiado (D'IPPOLITO;MEDEIROS, 2005).…”

EFEITOS DA ADMINSTRAÇÃO DO MIDAZOLAM EM DOSES DIFERENTES EM JIBOIAS Boa constrictor LINNAEUS, 1758 (SQUAMATA: BOIDAE)

“…The main objective of breeding boas in captivity is to supply the exotic and wild animals' market of snakes (1) . Properly performed chemical restraint is fundamental for the success of wild animals clinic.…”
