“…Em relação à descrição do trajeto da artéria ovárica na superfície do órgão, foram constatadas divergências entre os autores consultados, o que deve estar relacionado com as diversas denominações atribuídas aos diferentes segmentos do ovário, por exemplo, pelo pólo superior [10] e borda superior [4]. Adotou-se a nomenclatura indicada pelo Internacional Committee On Veterinary Gross Anatomical Nomenclature [28], isto é, extremidades tubárica e uterina; margens mesovárica e livre, também utilizadas por outros autores [1,38,45].…”

Comportamento da artéria ovárica em éguas sem raça definida (Equus caballus, Linnaeus, 1758)Behavior of the ovaric artery in crossbred mares (Equus caballus, Linnaeus, 1758) RESUMO Atualmente, na medicina veterinária, os estudos envolvendo reprodução de eqüinos e principalmente a qualidade das fêmeas, que na maioria das vezes são consideradas como receptoras, são de extrema valia, devido a ganho de produção e qualidade de plantel dos criadores, sendo assim, teve-se por objetivo estudar o comportamento da artéria ovárica em éguas, ou seja, a sua ramificação e distribuição no parênquima ovariano, para dar subsídios a um melhor entendimento das manobras de melhoramento genético e produção, focando aspectos morfológicos e fisiológicos da vascularização e viabilidade deste órgão na reprodução animal. Foram utilizados 68 ovários (34 pares) de éguas adultas sem raça definida, com diferentes idades, obtidas no Frigorífico Pomar, município de Araguari, MG. Verificou-se que a artéria ovárica apresenta um trajeto longo, flexuoso e espiralado, alcançando a glândula por meio da margem mesovárica, próximo à extremidade uterina. Esta artéria mantém o sentido ora dorsal ora ventral, segue em direção à extremidade tubárica, contorna-a até atingir a fossa ovárica, e penetra na glândula somente após ter percorrido toda a sua superfície. A artéria ovárica apresentou dois arranjos vasculares: um com emissão de 2 a 62 ramos dorsais e 4 a 46 ramos ventrais, durante seu percurso na margem mesovárica em 51 preparações (75%) e no outro arranjo a artéria ovárica, na extremidade uterina, dividiu-se em um ramo dorsal e outro ventral em 17 preparações (25%). Em relação às faces dos ovários, a face lateral apresentou um número maior de ramos que a face medial. Nos ovários direitos, os quadrantes mais irrigados foram, por ordem: o dorsocranial, o ventrocranial, o dorsocaudal e o ventrocaudal. Nos ovários esquerdos, foram: o ventrocranial, o dorsocranial, o ventrocaudal e o dorsocaudal. ABSTRACTActually, on veterinary medicine, studies related to equine reproduction and mainly female quality, that most of the time, are considerate carrier production females and have an extremely value due to production increase and breed quality came from the farmers, then the aiming of the research was to study the ovaric artery behavior in mares, related with a fine description of ramification and distribution at ovarian parenchyma for further basal studies on reproduction field and productions rates correlates to reproductive performance, focusing morphological and physiological features from this organ vascularization and viability on animal reproduction. Sixty eight ovaries from adult crossbred mares of different ages obtained at the Slaughterhouse Pomar, Araguari -MG, Brazil. It was observed that the ovaric artery presents a long, sinuous and spiral course, and reaches the ovarian gland though the mesovaric margin near the extremity of the uterus, running either in a dorsal or ventral position. Then it runs towards the end of the uterine tube, circling it ...

“…Anomalous blood vessels are interesting to know from a scientific point of view, as especially they so often lead to the understanding of obscure problems of phylogeny and ontogeny. (8,9) The development of kidneys begins in the pelvis and migrate to its final adult location in the lumbar region. In this process they either retain blood vessels from their original location or receive and incorporate new vessels along its pathway to the final location.…”

Pre-hilar segmental branching was seen in 111(29.06%) of the main renal arteries. Conclusion 31.9 % of our study population had multiple renal arteries. There was no significant difference with regard to the incidence of multiple renal arteries, between the two sexes nor on the sides. Prior knowledge of possible variations that may exist is important for the d i a g n o s t i c a n d i n t e r v e n t i o n a l radiologists, transplant surgeons and urologists. No detailed study has been done in a Sri Lankan population and in this regard our findings may provide some insight to the practising clinician in Sri Lanka.

“…Anatomical variation of the celiak trunk is due to the persistence or abnormal development of the ventral splanchnic arteries. According to the branching pattern of celiac trunk many variations have been reported [4]- [5]. These anatomical variations are common and usually asymptomatic.…”

Purpose of this study was to identify and evaluate the spectrum and prevalence of celiac axis (CA) variations and its branches. To study accurately the celiac trunk (CT) morphometry: its diameter, length, distance from superior mesenteric artery (SMA) and it's topography, as well as the diameter of SMA. Evaluation of the importance of these findings in patients' (pts) management. Methods and Materials: This prospective-single-center-study included: 133 consecutive pts referred to our clinic for abdominal-CTscans over a 9-month period. They underwent MDCT and MDCT angiography with 120 ml i/v contrast medium at an injection speed of 3.5 and 4ml/s, with 3D-reconstructions. Results: In our series, we identified normal trifurcation of CT (type-1-Michels) -84 pts(64%); type-2-Michels-3%; type -3-Mischel-1.3%;type 5-Mischel-1%;type6-Mischel-2%,the other anatomical variations of the celiac trunk no included in Michel's classification where found in 39 of patients (29% of cases). Regarding topography, CT origin was found opposite T12-L1 junction (37%), opposite T12 (31.9%) or L1 vertebra (31.1%). The length range of CT was: 1.17 to 4,5cm, its diameter: 0.4 to 1.13cm; its distance from SMA: 0.4 to 2.15cm; while the diameter ranges of SMA: 0.51 to 1.05cm. Conclusion: Our findings were similar to a certain range to previous studies. Recognition of CA variants requires a detailed description, and as previously noted a hypothetical anatomic model for summarizing the observed CA anatomical variations is needed. Recognition in detail of variations of CA anatomy and its morphometry is important in the accurate interpretation of disease, in diagnostic imaging, while it is indispensable in preventing complications during surgery/interventional radiology procedure.
