A six-year-old male neutered pug presented as an emergency with acute-onset dyspnoea. The patient was stabilised with a temporary tracheostomy. Further investigations revealed the presence of anatomical malformations commonly encountered in dogs suffering from brachycephalic obstructive airway syndrome (BOAS). A CT scan of the patient’s head also revealed the root of the right maxillary canine tooth (104) extending into the right nasal cavity. Rhinoscopic examination confirmed partial occlusion of the nasal airway by the presence of the tooth root. The right maxillary canine tooth was extracted, and postremoval rhinoscopy demonstrated an increase in the nasal cavity air-filled space on the right side. Subsequently, the patient underwent BOAS surgery but was unable to tolerate long-term removal of the tracheostomy tube postoperatively due to severe laryngeal collapse. A permanent tracheostomy was performed and the patient was discharged showing no signs of respiratory difficulties.
The use of extracorporeal shock wave therapy (ESWT) for the treatment of delayed or non-union of long bone fractures has been described in human patients with encouraging results. This case report describes the successful treatment of a mandibular fracture non-union with ESWT. To authors' knowledge, this is the first report of the clinical use of ESWT for the management of a non-union in a dog.
OBJECTIVESTo assess the prevalence of hiatal hernia (HH) in BOAS dogs and review the utility of the contrast-enhanced CT in the process of diagnosing HH in those patients.
METHODSA retrospective study was performed on the CT images obtained from 88 patients, 42 of them were contrast enhanced. All images were reviewed by 3 imagers and the presence of HH was assessed. The prevalence of HH was calculated within both the plain and the contrastenhanced groups.21 randomly chosen contrast-enhanced studies were initially viewed without the contrast in order to diagnose HH. Subsequently, they were re-assessed with contrast enhancement.
RESULTSIn the plain group HH was diagnosed in 28% of the cases, whereas among the contrast-enhanced studies HH was found in 50% of them. The assessment of the 21 studies showed that in 50% of the cases the presence of contrast changed the final diagnosis. Additionally, all the imagers equivocally stated that introduction of the contrast significantly increased the level of the decision confidence in borderline cases.
STATEMENT (CONCLUSIONS)The study revealed a high prevalence of HH in BOASaffected dogs. It also showed an increase in the detectability of HH, when the contrast CT is performed. Contrast-enhanced images allow more precise recognition of the tomographic features of HH and differentiation from other soft-tissue malformations such as esophageal diverticulum. To the author's knowledge, this the first study in the veterinary literature that describes the tomographic features of HH.
OBJECTIVESThe aim of this case report is to assess the relationship between the computed tomographic and the exploratory laparotomy findings in two dogs with retained surgical sponges.
METHODSTwo dogs were referred with a history of depression and chronic vomiting following previous ovariohysterectomy. Clinical examination revealed a palpable abdominal mass in both dogs. In the first dog computed tomography (CT) scan of the abdomen revealed a 36 x 44 mm well demarcated intramural small intestinal mass with air attenuating center surrounding by a soft tissue attenuating ring. In the second dog CT demonstrated a 32 x 31 mm well demarcated soft tissue attenuating peritoneal mass with no intestinal loops dis placement. Enhanced CT examination demonstrated peripheral ring enhancement of the mass in both cases finding compatible with the presence of abscess or granuloma.
RESULTSSurgical exploration was performed in both dogs. In the first dog, a retained surgical sponge was detected within the intestinal lumen and intestinal resection and anastomosis were followed. One day after surgery the dog had showed signs of intestinal dehiscence and
