Resumo

Com o objetivo de avaliar a ultrassonografia torácica (incluindo a ecocardiografia) como método de exame complementar em pacientes portadores de efusão pleural e/ou pericárdica, realizou-se a ultrassonografia torácica em 30 cães, machos e fêmeas de raças e idades variadas. Animais atendidos nos serviços de Pronto-Atendimento, Clínica Médica ou Clínica Cirúrgica do HOVET/USP com efusão pleural e/ou pericárdica, detectadas por meio de exame radiográfico, ultrassonografia emergencial ou toracocentese exploratória foram incluídos no estudo. Observou-se efusão pleural em 12 cães (40%), efusão pericárdica em oito (26,66%) e efusão pleural e pericárdica em outros dez cães (33,33%). A causa da efusão pleural e/ou pericárdica foram avaliadas ultrassonograficamente como sendo: nódulo/tumor cardíaco (5 - 16,66%), nódulo/tumor intratorácico (5 16,66%), insuficiência cardíaca congestiva por cardiomiopatia dilatada (4 13,33%) ou endocardiose de mitral e tricúspide (3 10%), efusão pericárdica idiopática (3 - 10%), li fossarcoma (2 - 6,66%), piotórax (2 6,66%), ruptura diafragmática (1 3,33%), hérnia peritônio-pericárdica (1 –3,33%), pneumonia e pleurite (1 - 3,33%), tumor de ovário com metástases torácicas (1 3,33%), pericardite infecciosa (cinomose) (1 3,33%) e hipoalbuminemia (1 3,33%).(AU)

To evaluate diagnostic accuracy of thoracic ultrasonography (including echocardiography) of patients with pleural and/or pericardial effusion, thoracic ultrasonography was performed in 30 dogs, males and females, of different breeds and ages. The animals were admitted to the Emergency, Internal medicine or Surgery department of the Faculty of Veterinary Medicine, University of São Paulo, presenting with pleural and/or pericardial effusion, diagnosed by thoracic radiography, emergency thoracic ultrasonography or exploratory thoracocentesis. Twelve (40%) dogs had pleural effusion, 9 (30%) had pericardial effusion and 9 (30%) had both pleural and pericardial effusions. The definitive cause of effusion were obtained by thoracic ultrasonography as follows: heart mass (5 –16,66%), intrathoracic mass (5 16,66%), congestive heart failure by dilated cardiomyopathy (4 13,33%) or mitral and tricuspid insufficiency (3 10%), idiopathic pericardial effusion (3 10%), lymphosarcoma (2 6,66%), pyothorax (2 - 6,66%), traumatic diaphragmatic hernia (1 3,33%), congenital peritoneopericardial hernia (1 3,33%), pneumonia and pleuritis (1 3,33%), ovarian neoplasia and thoracic metastasis (1 3,33%), infectious pericarditis (distemper) (1 3,33%) and hypoalbuminemia (1 3,33%). The conclusion was that thoracic ultrasonography was an excellent auxiliary exam in animals with pleural and/or pericardial effusion, and its not invasive and safe for the patient, allowing to guide biopsies and perform the exam in different decubits, avoiding patient stress.(AU)
