Case summary: A 10-year-old neutered female domestic shorthair cat was presented to our hospital with a 2-day history of anorexia, vomiting and lethargy. The biochemistry panel revealed increased hepatic enzyme activity and serum amyloid A concentration. Haematological values were within reference intervals. An abdominal ultrasound identified a hyperechoic spindle-shaped structure within the common bile duct and a suspected secondary subobstruction, associated with signs of intra- and extrahepatic biliary tract inflammation. During hospitalisation, the cat developed severe and sustained ionised hypercalcaemia. Exploratory surgery was elected as a result of the lack of clinical improvement, despite supportive treatment and suspected retrograde migration of the spindle-shaped structure. Two grass awns were extracted at the junction of an extrahepatic duct and the common bile duct via choledochotomy using intraoperative ultrasound guidance. A stent was then placed in the bile duct to prevent subsequent bile leakage. Histopathology of the liver revealed a moderate neutrophilic and lymphoplasmacytic inflammation with rare bacterial colonies. Escherichia coli was cultured from a bile sample. No specific cause of hypercalcaemia was identified. The cat recovered uneventfully from surgery. Hepatic enzyme activities and hypercalcaemia progressively decreased within a few weeks after surgery and remained within the reference intervals without treatment. Therefore, hypercalcaemia was suspected to be secondary to a foreign body-related granulomatous reaction. Relevance and novel information: To our knowledge, only one other feline case report of biliary tract obstruction secondary to a biliary foreign body has been described in the literature. This is also the first case reporting the use of intraoperative ultrasound to localise a vegetal foreign body within the biliary tract of a cat. This case is also unique because of the onset of hypercalcaemia suspected to be secondary to a foreign body-related granulomatous reaction. [ABSTRACT FROM AUTHOR]

Objective: The objective of this retrospective study was to report the clinical outcome of dogs with craniodorsal hip luxation (CDHL) treated with a modified prosthetic capsule technique (mPCT)., Animals and Procedure: Retrospective study of medical records from dogs with CDHL treated with mPCT between 2012 and 2018., Results: Sixty-four dogs were included. All luxations were reduced successfully. No intraoperative complications were observed. The postoperative complication rate was 28% ( n = 18), with 14% ( n = 9) major and 14% ( n = 9) minor complications, and the majority occurring within 1 mo after surgery. Complications included reluxation (9.4%), severe lameness (3%), osteomyelitis (1.6%), and intermittent lameness or stiffness (14%). Of dogs without major complication (33/55 dogs), long-term owner follow-up assessment (> 6 mo) (median: 39 mo, range: 19 to 51 mo) revealed an excellent or good quality of life, although 5 dogs had intermittent lameness or stiffness. Radiographs of 13/33 dogs (median: 27 mo, range: 10 to 46 mo) showed no or mild osteoarthritis progression., Conclusion and Clinical Relevance: The mPCT is an effective technique for surgical treatment of CDHL in dogs. Further studies are required to objectively evaluate limb use and long-term radiographic changes., (Copyright and/or publishing rights held by the Canadian Veterinary Medical Association.)

Case Summary: A 4-month-old female domestic shorthair kitten was presented for a congenital cleft palate causing nasal discharge and sneezing episodes. CT revealed a palatal bone defect involving 20% of the palatal area. Surgical correction of both the hard and soft palate defects was performed using the overlapping and medially positioned flap techniques, respectively. Complete healing of the wound and full resolution of the clinical signs occurred within a 1-month period. At 2 months postoperatively, two punctiform oronasal fistulae were observed rostrally without associated clinical signs. Control CT, performed 6 months postoperatively, revealed a 50% enlargement of the palatal bone defect. At 12 months postoperatively, the cat was still in good general condition without any clinical signs., Relevance and Novel Information: To the best of our knowledge, this is the first report to describe the treatment of a congenital cleft palate in a kitten using the overlapping flap technique with a successful medium-term clinical outcome, despite the formation of two oronasal fistulae. This suggests that, as in dogs, full restoration of oronasal compartmentation is not mandatory to achieve functional outcome. The increase of the palatal bone defect over time may play a role in late oronasal fistulae formation and should be considered for surgical planning., Competing Interests: Conflict of interest: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)
