| Popis: | The aim of this study was to evaluate the clinical, surgical and diagnostic imaging findings in 11 cats and 3 dogs with suspected acute and chronic traumatic diaphragmatic hernia, and to compare the results of positive contrast cheliography (peritoneography) taken immediately and 5 min after the injection of contrast material. Thoracic and abdominal radiography, ultrasonography, and positive contrast cheliography of all animals were performed. Eight cases were considered as acute and six cases were considered chronic. The contrast images taken immediately after the injection of contrast material revealed the contrast material in the thoracic cavity in 8/8 acute trauma patients, but in none of the chronic cases. In 5/6 of these cases contrast material was seen in the thoracal cavity only in additional images taken after 5 min. One patient was diagnosed with FIP and excluded from the study. Twelve cases had complete resolution and one animal died during the early postoperative period. Our results suggest that positive contrast cheliography performed immediately after the injection of contrast material may not reveal chronic cases of diaphragmatic hernia and a second imaging (or imaging after 5 min) is indicated in order not to overlook chronic cases. Cat, chronic, contrast medium, diaphragm, dog, peritoneography Traumatic diaphragmatic hernia most often develops as a result of blunt abdominal trauma (particularly motor vehicle accidents), resulting in sudden increase in abdominal pressure and subsequent disruption of the diaphragm which allows abdominal organs to migrate into the chest cavity (Schmiedt et al. 2003; Fossum 2007). Several reports in veterinary literature have described the pathophysiology, surgical approaches, and outcomes of traumatic diaphragmatic hernia (Wilson and Hayes 1986; Boudrieau and Muir 1987; Downs and Bjorling 1987; Minihan et al. 2004; Worth and Machon 2005). Herniation of abdominal organs into the thoracic cavity may result in the inability of the lung to inflate and, thus, respiratory dysfunction (dyspnea, tachypnea, cyanosis) is the most common presenting sign of reduced functional residual capacity (Garson et al. 1980; Wilson 1992). Other clinical signs such as a “tucked” (empty) abdomen or the presence of muffled heart sounds and/or absent lung sounds are helpful, but variably present (Worth |
