“…As in dogs, the major abdominal vessels were readily visualized in all wolves. The dimensions of the aorta cranially to its trifurcation as well as the left and right external iliac arteries reached mean values close to those reported for dogs by Kamikawa and Bombonato (2007), as shown in Table 4.…”

The aim of the present study was the ultrasound characterization of the abdominal and pelvic regions of five maned wolves kept in captivity at the Triage Center of Wild Animals of the Federal University of Viçosa (Centro de Triagem de Animais Silvestres, Universidade Federal de Viçosa). This characterization included descriptions of ultrasonographic aspects and measurements of various structures using B-mode ultrasound. Biometric data were collected to assess the existence of significant linear correlations between these measurements and the measurements obtained by ultrasound. Additionally, hematological and serum biochemistry evaluations of the animals were performed. The ultrasound findings were similar to those available in the literature on domestic dogs, which were used for comparison as a result of the lack of published data regarding maned wolves. The latter species showed characteristics closely resembling those of the former, differing in the spleen and left renal cortex echogenicities, in the appearance of the prostatic and testicular regions and in the hepatic portal vein morphology. In the current study, the biometric values were similar to those previously published; however, no data regarding thoracic perimeter, modified crown-rump length or thoracic depth were found in the literature for this Canidae species. Statistical analysis showed the existence of a strong negative correlation between the modified crown-rump length and left renal length, between the modified crown-rump length and the right renal volume, between the thoracic perimeter and the height at the cranial pole of the left adrenal gland and between the thoracic perimeter and the height at the caudal pole of the left adrenal gland. Laboratory findings, including segmented neutrophil, eosinophil, monocyte and lymphocyte counts and the serum levels of glucose, ALT, alkaline phosphatase, urea, total protein, globulin, creatine phosphokinase, triglyceride, sodium, phosphate, potassium and chloride, were inconsistent with values found by other authors. The ultrasound is a diagnostic imaging method that must be further explored in the medicine of wild animals; therefore, additional research in this area is required.INDEX TERMS: Maned wolf, abdominal ultrasound, pelvic ultrasound, biometrics.

“…A parte cranial da aorta abdominal (cranial à artéria frenicoabdominal esquerda) não é de fácil visibilização, especialmente em cães com tórax profundo, devido aos artefatos ocasionados pelo gás no trato gastrintestinal e pelas costelas. Às vezes, quando há muito gás, pode ser mais fácil obterse uma imagem sagital da região cranial da aorta em decúbito dorsal, medialmente ao rim direito (KAMIKAWA, 2003;SZATMARI et al, 2001). A aorta possui um perfil típico de velocidade de fluxo laminar do tipo achatado e a morfologia da onda é típica de um fluxo de padrão de alta resistividade.…”

“…Elas são responsáveis pela irrigação da pelve e se originam simetricamente da superfície lateral da aorta. Caudal a este ponto, a aorta torna-se a artéria sacral mediana (KAMIKAWA, 2003). Sugere-se o decúbito lateral para avaliá-las, pois nesta posição há menor atenuação do feixe sonoro pelos tecidos superficiais.…”

“…A veia cava caudal está sempre ao lado da veia porta e apresenta-se como um vaso retilíneo e paralelo neste ponto e que, depois, apresenta um curso curvilíneo. A veia porta principal é ventral e situa-se ligeiramente à esquerda da veia cava caudal (KAMIKAWA, 2003). Nesta parte cranial, a morfologia de onda é mais periódica e fásica do que em sua região caudal, correspondendo às condições de pressão do átrio direito, uma vez que as alterações de pressão intratorácica e intra-abdominal ocorrem devido aos movimentos respiratórios (CERRI et al, 1998).…”

“…Os ramos portais intra-hepáticos têm parede ecogênica, o que torna sua identificação mais fácil em relação às veias hepáticas (estas últimas não apresentam paredes evidentes). As paredes das veias hepáticas são hiperecóicas somente quando o feixe sonoro incidente e o vaso estão perpendiculares (KAMIKAWA et al, 2003).…”

Renal diseases are common in older cats. Decreased renal blood flow may be the first sign of dysfunction and can be evaluated by Doppler ultrasound. But previous studies suggest that the resistive index (RI) has a low sensitivity for detecting renal disease. Doppler waveforms of renal and intrarenal arteries demonstrate decreased blood flow before there are any changes in the RI. The purpose of this study was to evaluate the normal Doppler flowmetrics parameters of renal arteries (RAs), interlobar arteries (IAs) and abdominal aorta (AO) in adult healthy, Persian cats. Twenty-five Persian cats (13 females and 12 males with mean age of 30 months and an age range 12-60 months) with normal clinical examinations and biochemical tests and normal systemic blood pressure were given B-mode ultrasonographies in order to exclude all nephropathies, including polycystic kidney disease. All measurements were performed on both kidneys. Both kidneys (n=50) were examined by color mapping of the renal vasculature. Pulsed Doppler was used to examine both RAs, the IAs at cranial, middle and caudal sites, and the AO. The RI was calculated for all of the vessels. Early systolic acceleration (ESA) of RA and IA was obtained with Doppler spectral analysis. Furthermore, the ratio indices between RA/AO, and IA/RA velocities were calculated. The mean values of peak systolic velocity (PSV) and the diameter for AO were 53.17±13.46 cm/s and 0.38±0.08 cm, respectively. The mean RA diameter for all 50 kidneys was 0.15±0.02 cm. Considering the velocimetric values in both RAs, the mean PSV and RI that were obtained were 41.17±9.40 cm/s and 0.54±0.07. The RA had a mean ESA of 1.12±1.14 m/s(2) and the calculated upper limit of the reference value was 3.40 m/s(2). The mean renal-aortic ratio was 0.828±0.296. The IA showed PSV and RI values of 32.16±9.33 cm/s and 0.52±0.06, respectively. The mean ESA of all IAs was 0.73±0.61 m/s(2). The calculated upper limit of the reference value was 2.0m/s(2). The mean renal-interlobar artery ratio was 1.45±0.57. The RI values obtained in this study were similar to values reported in the literature. Some conditions that lead to a decrease in compliance and to an increase in vascular resistance can affect the Doppler spectral waveforms without changes in RI. To our knowledge, there are no studies that were directed toward to the normal ESA values of the renal vasculature in Persian cats. This study introduced a new ratio between the PSV of the RA and the IA. This index was developed based on the well-known effects of Doppler on the detection of stenosis, regardless of the cause. Further studies are necessary to verify the hemodynamic behavior of this index under pathological conditions in cats as well as the effect of aging, nephropathies and systemic pressure on Doppler velocimetric parameters.
