ABSTRACT
Background: The myxomatosis degeneration is a degenerative cardiac valve disease, with a higher incidence in maleand senile canids. The diagnosis is made by a doppler echocardiography exam. Although there are few reports on the occurrence of cardiopathies in wild dogs (Cerdocyon thous), some studies on their cardiological parameters can be found.Considering this, and knowing that the cardiopathies in wild canids are common post mortem findings, the objective of thisstudy is to describe the echocardiography diagnosis of a case of myxomatous degeneration of the atrioventricular valvesin 1 wild dog (Cerdocyon thous) living in captivity.Case: It was treated at the Diagnostic Imaging Department of the Veterinary Hospital of the Federal University of Mato Grosso(HOVET-UFMT), 1 wild dog (C. thous), male, living in captivity with approximately 10-year-old, directed by the Center ofMedicine and Research in Wild Animals of Cuiabá, to perform echocardiography exam. The patient was submitted to anesthesiafor proper examination, which was used Esaote® machine model MyLabFive VET with sector scan transducer (4.0 -7.5 MHz).The longitudinal, transverse and apical scan planes were obtained through left and right parasternal windows. The evaluation ofM mode exposed ejection fraction and shortening increased, of 81% and 47%, respectively, however it showed no increase insystolic and diastolic values of left ventricle, nor in right cavities on subjective evaluation. The relation between the left atrium(LA) and the aorta (Ao) remained normal, at 1.2 mm, with dimensions of 13.4 mm from the AO and 16.3 mm from LA, compatible with species parameters or domestic canines. The atrioventricular valves showed thickening and irregularities in their cusps,with great intensity in the left atrioventricular valve (LAV). The Doppler mode analysis revealed a turbulent systolic flow into the...

Background: The urethral prolapse in dogs is a rare condition known by the protrusion of the urethral mucous membrane and the external orifice of the urethra. It is more frequently seen in young males, especially of brachycephalic breeds, for instance the English bulldog. Despite the pathophysiology of this disorder being little elucidated, it is believed that the cause is related to factors such as genetic susceptibility, excessive sexual behavior, traumas, abnormalities and urinary and prostatic problems. Due to limited reports on the subject, this paper aims to describe the clinical and surgical aspects of a case of urethral prolapse in a dog, surgically corrected.Case: Admitted to the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT) a dog, American Pit Bull, 7 months old, with previous history of bleeding in the penile region and pain while urinating. In the physical exam it presented: intermittent bleeding via external ostium of the urethra, increased volume and protrusion of the distal urethral mucous membrane and the external orifice of the urethra, which was presenting a round shape mass, edematous and little congested of red-purplish coloring, evidenced by the passing of urethral probe. The diagnosis of urethral prolapse was confirmed and, after conducting laboratory tests and obtaining normal results for the species, the animal was sent to surgery. It was opted for the technique of resection and anastomosis of the protruded portion of the mucous membrane. After the anesthetic protocol, it was performed the trichotomy and antisepsis of region, the fenestrated drapes were properly positioned and the urethral catheterization was done, afterwards 3 points of support were produced with nylon thread 3-0, involving the urethra and the external portion of the penis.[...]
