RESUMO -Foram estudadas cinco Podocnemis expansa, fêmeas, cujo peso variava de 550 a 850 g. Os animais tiveram seu sistema arterial injetado com solução corada de látex sintético, fixados e armazenados em solução aquosa de formaldeído a 10%. Após abertura da cavidade celomática, as artérias mesentéricas cranial e caudal foram dissecadas. Encontrou-se a artéria mesentérica cranial como um ramo do tronco celíaco-mesentérico e originando as artérias pancreaticoduodenal caudal, ileocólica e jejunais, que irrigam o duodeno, pâncreas, cólon, íleo e jejuno, respectivamente. A artéria mesentérica caudal origina-se da aorta (60%) ou da artéria ilíaca comum (40%), distribuindo-se para o cólon e reto.Palavras chave: Podocnemis expansa, Artérias, Intestino, Anatomia.ABSTRACT -An anatomic study has been carried out on the mesenteric arteries of five Podocnemis expansa females weighing from 550 to 680 g. The animals had their artery system injected with a latex solution colored with a specific pigment and were then fixed in a 10% formol solution. After the coelomatic cavity being opened the cranial and caudal mesenteric arteries were dissected. It has been found that the cranial mesenteric artery is a branch of the coeliac mesenteric trunk while the cranial mesenteric artery gives off the pancreatic-duodenal , ileocolic and jejunal arteries that irrigate the duodenum, pancreas, colon, ileum and jejunum respectively. The aorta gives origen of as much as 60% of the caudal mesenteric artery, the remaining 40 % being originated from the common ileac artery, their branches reaching the colon and the rectum.Key words: Podocnemis expansa, Arteries, Gut, Anatomy. IntroduçãoAs funções primárias do trato digestório são a digestão e absorção de nutrientes essenciais aos processos metabólicos dos animais, além de revelar hábitos alimentares gerais, sendo útil para a sistemática. Os nutrientes digeridos são absorvidos pelo epitélio e transferidos para a circulação (HILDEBRAND, 1995

Electronic poster abstractsfetuses and evaluate their clinical values in differentiating mega cisterna magna from Dandy-Walker malformation. Methods: Totally 350 normal singleton fetuses between 21 and 32 weeks of gestation were enrolled. Fourteen fetuses with mega cisterna magna contemporarily and twelve fetuses with Dandy-Walker malformation previously were control group A and B respectively. Three-dimensional ultrasound (3D US) with volume contrast imaging (VCI) of GE Voluson Expert E8 was used. CTA is an angle of two single line, one is a line joined from the front edge and the posterior border of the cavum septum pellucidum, the other is a tangent line of the tentorium. The correlations of CTA with gestational age were analysed by Pearson correlation. The consistency and repeatability was investigated by Bland-Altman plot analysis and intraclass correlation coefficient. CTA of the control group A and B were compared with those of the normal fetuses by t-test. There were significant differences if P<0.05. Results: In these normal fetuses, CTA showed no correlations with gestational age (r = 0.014, P > 0.05). CTA of the control group A were not significantly different from the normals (56.66 ± 4.18 • vs 55.82 ± 5.32 • , t= 0.56, P > 0.05), while CTA of the control group B were significantly smaller than the normals and the control group A(32.76 ± 6.23 • vs 55.82 ± 5.32 • , t = 25.12, P < 0.05; 32.76 ± 6.23 • vs 56.66 ± 4.18 • , t= 26.04, P < 0.05). The repeatability of the same physician and the consistency between two different physicians were good, their intraclass correlation coefficient and 95% confidential interval were 0. 95 (0.88-0.97) and 0.88 (0.76-0.94

Twenty thre (23) cases of congenital diaphragmatic hernias managed at the Fetal Medicine Unit of the Faculdade de Medicina do ABC are presented. All cases were evaluated with bi-dimensional ultrasound and magnetic resonance imaging (MRI). In all cases, MRI allowed a detailed antenatal evaluation of the compressed lung and herniated organs, as well as the visualization of the volume and texture of the unaffected lung. The LHR was calculated using the MRI software and manual tracing. A total of 15/17 cases with an MRI calculated LHR ratio greater than or equal to 1 had good neonatal prognosis. Of the 06 cases with a LHR < 1, 06 died. Besides facilitating the identification of fetal organs herniated in the thorax, MRI also allows a precise calculation of the LHR, which is useful in the prognosis of congenital diaphragmatic hernias. Objectives: To prove the capability of ultrasonographers to recognize fetal anatomy and define anomalies from magnetic resonance imaging (MRI) compared with ultrasound studies (US). Methods: T2-weighted images from different sequences of part or the entire fetal bodies were obtained on a 1.5 Tesla unit by a technician. Then the images were analyzed by ultrasonographers, no use to analyzed MRI. The MRI acquisition sequences for each study were graded for the quality of the images in order to see the specific fetal structure: Grade 1; had poor images, no good for analysis. Grade 2; anatomy can be recognized, but not good for diagnosis. Grade 3; had good images, and it was possible to make diagnosis, and Grade 4: had excellent images, better than US and good for diagnosis. Data are presented as mode (range). P43.03Results: we studied a total of 221 acquisition sequences obtained in 17 fetuses (13 for each fetus). Grade 4 (3-4) were obtained in the visualization of head shape (scull), lateral ventricles, thalami, cerebellar hemispheres and vermis, cisterna magna, bulb, placenta and uterine wall. Grade 3 (2-4) were obtained in the visualization of face, thraquea, larynx, choroids plexus, corpus callosum, thalami, spine, conus medullaris, abdominal wall, liver, diaphragm, lungs, amniotic fluid. Grade 3 (1-4) were obtained in the visualization of kidneys, bladder, stomach, extremities, genitals. Grade 1 (1-2) were obtained in the visualization 4 chamber view and the outflow tract. MR images add more information in the prenatal diagnosis of fetal malformations in 4/17 cases. But two associated heart anomalies were not seen from MR images (interventricular septum defect and AV canal), both anomalies were easily seen with US. Conclusion: Not experienced ultrasonographers in MRI can understand easily the fetal anatomy (with the exception of heart morphology), and in some cases adding more information and details from MRI, increasing the power of prenatal diagnosis by using only US. P43.04The diagnostic value of fetal liver MRI in cases of congenital haemochromatosis We report two cases of hydropic fetuses diagnosed during routine third trimester ultrasound (US). In each case, fetal anaemia was susp...
