“…In veterinary medicine, there have been case reports of only 12 dogs [5][6][7][8][9][10][11][12][13][14][15]; however, the accurate incidence rate remains unknown in clinical settings. In particular, two reports have described dogs showing SI concurrently with an extrahepatic portosystemic shunt (EHPSS) and azygos continuation of the caudal vena cava (CVC) [8,16].…”

Background The normal visceral arrangement is called situs solitus, whereas the state of the visceral arrangement in a mirror-like positional relationship is called situs inversus. Among the SI, the state in which the positions of only some thoracoabdominal organs are reversed is called situs inversus partialis, and the state in which the positions of all thoracoabdominal organs are reversed is called situs inversus totalis (SIT). Clinical information on dogs with SIT is limited. Case presentation A 4-month-old Shiba dog was referred with depression and neurological symptoms as the chief complaints. Computed tomography (CT) revealed the patient had SIT with an extrahepatic portosystemic shunt (EHPSS) and azygos continuation of the caudal vena cava. In addition, complete reversal of the lung lobes and cardiovascular system in the thoracic cavity was confirmed. The patient underwent surgery for partial attenuation of EHPSS on day 8 after the initial examination. On day 124, after the initial examination, a second surgery was performed for complete attenuation. Under celiotomy, the positions of all abdominal organs, except for the rectum, were inverted; thus, SIT was confirmed via gross observation. In addition, the braided nylon sutures partially attenuated the concurrent splenocaval shunt. At the conclusion of this study, approximately 6 years had passed since the second surgery, and the patient had a good general condition without any medications. Conclusion In SIT, the complex anatomy of the abdominal organs and vessels is difficult to identify via gross observation; in contrast, CT is effective for detecting vascular abnormalities, confirming the anatomical position of each organ, and it allows for the definitive diagnosis of SIT.

“…In addition to humans, there are reports of SIT and dextrocardia in different species of animal, both domestic and wild, including fish [10], pigs [11], cats [12], dogs [13,14,15], horses [16], and rodents [17,18,19]. Within the latter, these anatomical alterations have been described in both Wistar and Sprague Dawley (SD) rats [17,18].…”

Situs inversus totalis is a condition where there is a transposition of all internal organs from their normal anatomical location. This infrequent and rare congenital condition has been described in several species of mammals. Dextorcardia is a series of conditions associated with an abnormal congenital positioning of the heart, and is often associated with situs inversus totalis. Here we report a case of situs inversus totalis and two cases of dextrocardia identified in Sprague Dawley rats during gross necropsy evaluations at both the Health Sciences North Research Institute (HSNRI) in Canada and Finlay Institute of Vaccine Research and Production in Cuba. The intent of this report is to share our findings and aid in the accumulation of data on these rare conditions.

“…A alteração congênita Situs inversus é considerada rara, pouco relatada nos mamíferos, sendo definida pelo desenvolvimento dos órgãos no lado oposto de sua anatomia fisiológica (JERRAM et al, 2006;SALMAN et al, 2010;SHIRAIWA et al, 1995;SOUZA JUNIOR et al, 2011). Existem relatos de Situs inversus em uma gama imensa de espécies, entre elas, humanos, animais domésticos e silvestres (BAKER-COHEN, 1961;EVANS, 1987;JERRAM et al, 2006;KAYA et al, 2002;LARSEN;KIRK, 1987;NEIL et al, 2002;PINHEIRO et al, 2014;RIES;KÖNIG, 1988;SHIRAIWA et al, 1995;TURNER;JONES, 2004). A ocorrência desta alteração corresponde a 0,01-0,2% em ratos e 0,01-0,02% em humanos (JERRAM et al, 2006;SHIRAIWA et al, 1995), sem predisposição sexual (WILHELM; HOLBERT, 2015) e geralmente assintomática (SALMAN et al, 2010).…”

RESUMOitus inversus, uma alteração rara na qual os órgãos se desenvolvem no lado oposto de sua localização habitual, já foi relatada em diferentes espécies. Seu diagnóstico é baseado nos exames por imagem, sendo geralmente um achado ocasional. Diante da raridade da alteração, o objetivo foi descrever a ocorrência de Situs inversus totalis em um animal experimental, por meio de exame radiográfico e de necropsia. Uma rata albina Wistar, com 16 semanas, utilizada para estudo experimental independente, foi submetida à radiografia torácica e abdominal, sendo observada diferente disposição dos órgãos internos. Após o término do experimento, procedeu-se a necropsia do animal, em que foi observada a localização oposta à anatômica dos órgãos: fígado, baço, estômago, ceco, pulmão e coração, caracterizando Situs inversus totalis com dextrocardia.
