Aspectos ultrassonográficos dos componentes umbilicais de bezerros da raça Holandesa durante o processo de involução fisiológica

Abstract: RESUMO Afecções umbilicais são comumente encontradas nos bezerros durante o período neonatal, podendo ocasionar graves complicações. Seu diagnóstico muitas vezes não é preciso pela palpação abdominal, sendo a ultrassonografia um valioso exame complementar, pois permite precisão na localização e na extensão das onfalopatias intra-abdominais. Diante disso e da raridade de pesquisas com estabelecimento de padrões ultrassonográficos do umbigo, o presente estudo propôs padronizar os aspectos das imagens ultrassonog… Show more

“…Umbilical evaluation was performed weekly in the morning, consisting of physical examination of external and internal components by inspection and bimanual abdominal palpation, as described by Watson et al (1994), performed on animals up to 30 days old. The 52 animals that showed umbilical changes identified on physical examination were subjected to ultrasound examination, in mode B, of the umbilical components (Bombardelli et al, 2018) to confirm the changes. To this end, M5vet equipment (Mindray Medical Brazil Limited, São Paulo, SP) was used, with a linear transducer maintained at a frequency of 7.5 MHz.…”

“…The navel consists of the veins, arteries, and urachus (Spurway et al, 2012). After a few days of birth, the abdominal wall of the umbilical region closes completely at 3 to 4 weeks (Bombardelli et al, 2018), and the arteries and veins undergo fibrosis giving rise to the lateral ligament of the bladder and round ligament of the liver, respectively, and progressive atrophy of the urachus occurs and it becomes a trace in the urinary vesicle (Mulon and Desrochers, 2005;Baird, 2008).…”

“…The efficiency of ultrasonography in evaluating umbilical structures, and its agreement with physical postmortem findings has been proved (Staller et al, 1995;O'Brien and Forrest, 1996). Many other studies have investigated the ultrasonographic appearance of umbilical structures in clinically healthy calves, and have evaluated their involution during the first weeks of life (Lischer and Steiner, 1993;Watson et al, 1994;Bombardelli et al, 2018). Through a standardized ultrasonographic technique, these authors determined the size of the umbilical structures, establishing a range of normal values for these structures, that can be used as a reference for calves with suspected umbilical abnormalities.…”
