Background: Congenital extrahepatic portosystemic shunts (CEHPSS) are rare in cats.Outcome after attenuation of CEHPSS with thin film has been described in a small number of cases.Objectives: To describe the clinical presentation, postoperative complications, and outcome of cats treated with thin film to attenuate CEHPSS.Animals: Thirty-four cats with CEHPSS were identified from the database of 3 institutions over 9 years.Methods: Retrospective study. Medical records were reviewed to identify cats with a diagnosis of a CEHPSS that underwent surgical attenuation. Congenital extrahepatic portosystemic shunts were suspected from clinical signs, clinicopathologic findings, and diagnostic imaging, and confirmed at exploratory laparotomy. Cats treated with thin film band attenuation were included. Postoperative complications and follow-up were recorded.Results: Complications were recorded in 11 of 34 cats. Deaths related to CEHPSS occurred in 6 of 34; 4 cats did not survive to discharge. Persistent seizures were the cause of death in 4 cats. Seizures were recorded in 8 of 34 cats after surgery; all these cats received preoperative antiepileptic drugs. Serum bile acid concentrations normalized in 25 of 28 of the cats for which data was available. Three cats had persistently increased serum bile acid concentrations and underwent a second exploratory laparotomy. One had a patent shunt, the other 2 had multiple acquired portosystemic shunts. Median follow-up was 8 months (0.5-84 months).Conclusions and Clinical Importance: Congenital extrahepatic portosystemic shunts attenuation using thin film in cats carries a good short-and mid-term prognosis if they survive the postoperative period. Seizures were the most common cause of death.

A ureteral rhabdomyosarcoma was diagnosed in a 2-year, 9-month-old, entire, male dobermann with persistent haematuria. Diagnostic imaging revealed unilateral hydronephrosis and hydroureter. In addition, it showed thickening of the distal ureteric wall and focal thickening of the mucosa of the bladder trigone between the ureters. No mass was identified. The patient underwent exploratory laparotomy, and biopsies of the bladder mucosal thickening and right ureteral thickening were obtained. Histopathology of the ureteral thickening was suggestive of a ureteral rhabdomyosarcoma. A right ureteroneocystostomy was performed, and histopathology confirmed the suspected ureteral rhabdomyosarcoma, which was fully excised. Six months later, the patient remains asymptomatic with no evidence of recurrence or metastases on abdominal ultrasonography.

Multiple magnet ingestion requires emergency treatment given the serious associated complications. A four-year, 10-month-old male neutered Border collie was referred for investigation of generalised tonic-clonic seizures. On presentation, there was an episode of vomiting and possible ingestion of two ‘Rattle magnets’. Physical and neurological examination was unremarkable apart from mild cranial abdominal discomfort. Abdominal radiographs revealed the presence of two metallic foreign bodies suspected to be within the pyloric antrum and three mineralised foreign bodies within the small intestine. Endoscopy revealed the presence of one magnet in the pyloric antrum. After removal, a deep erosion of the gastric mucosa was observed. Gastroprotectants were administered and repeated abdominal radiographs showed the second magnet within the intestine. Thirty-six hours later, the patient passed faeces containing three stones and one magnet and was discharged without further gastrointestinal signs or complications, prior to returning for neurological investigations.
