Objetivou-se descrever a utilização das técnicas Doppler e elastografia ARFI (acoustic radiation force impulse) na avaliação de neoplasias mamárias de gatas, métodos ainda não utilizados para tal estudo em fêmeas felinas. Após a avaliação física e específica das neoplasias mamárias de duas gatas, foram realizadas as avaliações ultrassonográfica modo-B (ecogenicidade, ecotextura e margeamento), Doppler colorido (característica do fluxo sanguíneo) e espectral (velocidade sistólica/VS; diastólica/VD; e índice de resistência/IR) e a eslatografia ARFI qualitativa (escala de cores) e quantitativa (velocidade de cisalhamento) dos nódulos mamários, avaliando a aplicabilidade destas técnicas para determinar a malignidade dos tumores mamários. Após mastectomia e...

ABSTRACT To describe the ARFI elastography in the evaluation of the adrenal glands in adult dogs, to evaluate the stiffness of adrenal parenchyma and to determine the qualitative and quantitative standards of the ARFI technique, which have not yet been described in veterinary medicine. Sixty adrenal glands from thirty healthy adult dogs were evaluated by B-mode and qualitative and quantitative ARFI elastography to assess the stiffness of healthy parenchyma and to determine the quality and quantity (shear velocity) standards of ARFI technique in body, cranial and caudal adrenal poles. Findings of ultrasonography evaluations were normal. Qualitative elastography showed that adrenal glands were not deformable and presented homogeneous middle-gray areas. The...

Acoustic radiation force impulse (ARFI) elastography of testicular disorders in dogs: preliminary results
Provedor de dados: 45
Autores: Feliciano,M.A.R.; Maronezi,M.C.; Simões,A.P.R.; Maciel,G.S.; Pavan,L.; Gasser,B.; Silva,P.; Uscategui,R.R.; Carvalho,C.F.; Canola,J.C.; Vicente,W.R.R.
The aim of this study was to describe the use of acoustic radiation force impulse (ARFI) elastography in the evaluation of testicular disorders in dogs. Eighteen dogs with testicular disorders (thirty-six testicles) were assessed. Echotexture, size, contours and margins of testes were analysed by ultrasonography. Deformities and tissue stiffness (greyscale and homogenous or heterogeneous) were evaluated by qualitative elastography and shear velocity was determined quantitatively. Subsequent to orchiectomy, testicular samples were collected for histopathology analysis and thirty-six disorders were identified. Qualitative elastography revealed that normal healthy testicular tissues were homogenous and not pliable while the affected testicles had alterations...

B-mode and Doppler ultrasonography of adrenal glands of healthy dogs
Provedor de dados: 45
Autores: Fernandez,S.; Feliciano,M.A.R.; Crivellenti,S.B.; Crivellenti,L.Z.; Simões,A.P.R.; Maronezi,M.C.; Uscategui,R.R.; Capela,C.R.; Gilor,C.; Santana,A.E.; Vicente,W.R.R.
ABSTRACT The aim of this study was to determine the vascular indices of adrenal blood flow in healthy dogs (systolic velocity - SV; diastolic velocity - DV; resistance index - RI). Eighteen dogs (thirty six adrenal) were studied. Physical examination, biochemical profile and dexamethasone suppression test were performed to determine general health status. Echotexture, size, contours and margins, and overall shape of the adrenal gland (right and left) were assessed via ultrasound. By spectral Doppler of the phrenic-abdominal artery, the SV, DV, and RI were acquired. Animals did not show alterations in clinical and laboratory examination and suppression of cortisol. Normal homogeneous and echotexture, regular contours and margins and normal shape and size...

Spleen evaluation using contrast enhanced ultrasonography and Doppler in dogs with subclinical ehrlichiosis
Provedor de dados: 45
Autores: Maronezi,M.C.; Feliciano,M.A.R.; Crivellenti,L.Z.; Borin-Crivellenti,S.; Silva,P.E.S.; Zampolo,C.; Pavan,L.; Gasser,B.; Simões,A.P.R.; Maciel,G.S.; Canola,J.C.; Vicente,W.R.R.
The aim of this study was to evaluate the splenic parenchyma of dogs with subclinical ehrlichiosis using Doppler and contrast-enhanced ultrasonography and provide reference values for this organ in affected animals. Seventeen dogs naturally infected with E. canis were selected for this study. Splenic parenchyma echotexture and echogenicity, size and borders were determined by ultrasound scan. The vascular indices of the splenic artery were determined by Doppler. SonoVue, at 0.1mL per animal, was used in microbubble contrast-enhanced ultrasonography to determine wash in, wash out and peak enhancement time in the splenic tissue. B-mode ultrasonography revealed splenomegaly with rounded borders, heterogeneous echotexture and mixed echogenicity. The vascular...

Pulmonar ARFI elastography and ultrasonography of canine fetal hydrops: case report
Provedor de dados: 45
Autores: Maronezi,M.C.; Madruga,G.M.; Uscategui,R.A.R.; Simões,A.P.R.; Silva,P.; Rodrigues,M.G.K.; Cintra,C.A.; Assis,A.R.; Vicente,W.R.R.; Feliciano,M.A.R.
ABSTRACT This case report describes diagnostic and prognostic applicability of pulmonary acoustic radiation force impulse elastography and ultrasonography in canine hydrops fetalis. We also explore these methods’ potential in prediction of postnatal respiratory dysfunction. Two pregnant bitches (English bulldog [case 1] and French bulldog [case 2]) were referred for sonographic evaluation in their last week of pregnancy. Ultrasound showed that in each bitch, one fetus presented with lung alterations (hyperechogenicity, irregular surface, and pleural effusion) and anasarca. The other fetuses of the litter were normal, and they were observed as light gray and dark blue on pulmonary elastography. Their shear-wave velocity was 0.75m/s. Fetuses with hydrops...

Provedor de dados: 45
Autores: Silva,P.E.S.; Nunes,N.; Gering,A.P.; Prada,T.C.; Simões,A.P.R.; Bompadre,T.F.V.; Castro,R.V.G.; Paula,D.P.
ABSTRACT The aim of this study was to evaluate the effect of epidural bupivacaine administration at the first lumbar vertebra on cardiopulmonary variables, arterial blood gases and anti-nociception. Sixteen healthy female dogs were randomly assigned into two groups based on bupivacaine dose: G1 group, 1mg kg-1 or G2 group, 2mg kg-1, diluted in the same final volume (1mL4kg-1). Cardiopulmonary variables were measured and arterial blood gas was collected (T0), it was repeated 10 minutes after intravenous administration of butorphanol 0.4mg kg -1 (T1). Anesthesia was induced with intravenous etomidate at 2mg kg-1 and the epidural catheter was introduced and placed at the first lumbar vertebra. Thirty minutes later, bupivacaine was administered epidurally....
