Resumo

Interventricular septal defect (IVSD) is a congenital heart disease characterized by communication or non-closure of the interventricular septum in the embryonic or postnatal period, causing a failure in the separation between the systemic and pulmonary circulation. The severity of the hemodynamic consequences depends on the extent of the defect and the magnitude of the flow through it. Blood flow commonly occurs from left to right, because systemic vascular resistance is greater than pulmonary resistance. This report describes the echocardiographic findings in a 4-year-old male Poodle treated at the Veterinary Hospital with a history of exercise intolerance, cyanosis and episodes of syncope. On echocardiography, perimembranous IVSD was diagnosed with atrial and right ventricular dilatation, discontinuity of the interventricular septum in the subaortic region measuring approximately 5 mm. In the Doppler evaluation, reverse turbulent flow was evidenced, characterizing shunt from right to left (Eisenmenger syndrome). Despite preserved systolic function, abnormal relaxation was observed. Doppler echocardiography was a fundamental complementary imaging test for the diagnosis of this congenital heart disease since its suspicion is not commonly raised in adult patients. Doppler echocardiography allowed us to identify the defect, define its size and extension, determine the direction of blood flow as well as its hemodynamic consequences.(AU)


O defeito do septo interventricular (DSIV) é uma cardiopatia congênita caracterizada pela comunicação ou não fechamento do septo interventricular no período embrionário ou pós-natal, causando falha na separação entre a circulação sis-têmica e pulmonar. A gravidade das consequências hemodinâmicas depende da extensão do defeito e da magnitude do fluxo através dele. O fluxo sanguíneo comumente ocorre da esquerda para a direita, porque a resistência vascular sistêmica é maior do que a pulmonar. Este relato descreve os achados ecocardiográficos em um Poodle, macho, de 4 anos atendido no Hospital Veterinário com história de intolerância ao exercício, cianose e episódios de síncope. Ao ecocardiograma foi diagnosticado DSIV do tipo perimembranoso com dilatação atrial e ventricular direita, descontinuidade do septo interventricular em região subaórtica medindo aproximadamente 5 mm. Na avaliação Doppler, evidenciou-se fluxo turbulento reverso, caracterizando shunt da direita para a esquerda (síndrome de Eisenmenger). Apesar da função sistólica preservada, foi observado relaxamento anormal. A ecocardiografia Doppler foi um exame de imagem complementar fundamental para o diagnóstico dessa cardio-patia congênita, uma vez que sua suspeita não é comumente levantada em pacientes adultos. A ecocardiografia Doppler per-mitiu identificar o defeito, definir seu tamanho e extensão, determinar a direção do fluxo sanguíneo, bem como suas conse-quências hemodinâmicas.(AU)

Background: Ureteral ectopia (or ectopic ureter) is a congenital anomaly of the urinary system in which the ureter insertsanywhere other than the vesical trigone. This anatomical change may have unilateral or bilateral involvement. The mostevident clinical sign, occurring mostly in females, is urinary incontinence, however in some cases the condition may progressto nephritis and dilation of the renal pelvis. The diagnosis is established through imaging, and definitive treatment requiressurgical approach. The present study reports a case of ureteral ectopia in a dog which was diagnosed by ultrasound andcontrast radiography (excretory urography) and successfully treated by neoureterostomy.Case: A 10-month-old female American Pit Bull Terrier was attended at the Veterinary Hospital of the Federal Rural University of the Semi-Arid (UFERSA), in Mossoró, RN. Her owner reported incontinence of dark, malodorous urine sincebirth as the chief complaint. After clinical examination, cystitis was suspected, and a complete blood count, urinalysis,and abdominal ultrasound was requested. The blood count and creatinine were within the reference values. The presenceof struvite crystals were found on urinalysis. Ultrasound examination revealed a tortuous, dilated right ureter from therenal pelvis to the urinary bladder; no uroliths were identified as a cause of potential obstruction, but the ipsilateral kidneyshowed increased cortical echogenicity, loss of corticomedullary definition, and moderate pelvic dilation. These findingssupported a presumptive diagnosis of ectopic ureter. For the purpose of confirming this suspicion, excretory urography wasperformed, revealing unilateral ureteral dilation and radiopaque contrast uptake following the path of the urethra. Once thediagnosis was confirmed, surgery was performed to correct the ureteral ectopia using the standard...
