“…25 Another common complication in cats with EHPSS before and after attenuation is acute central blindness. 3,4,6,7,8,9,26 Blindness that occurs secondary to hepatic encephalopathy is usually accompanied by other clinical signs, including ataxia, head pressing, and circling. 27 In this study, five cats had either persistent or intermittent blindness prior to surgery, and two developed postoperative blindness.…”

ObjectiveTo report the clinical perioperative, short‐term, and long‐term outcomes for cats undergoing ameroid ring constrictor (ARC) attenuation of a congenital extrahepatic portosystemic shunt (EHPSS).Study designRetrospective case series from a single veterinary teaching hospital (2002–2020).AnimalsTwenty client‐owned cats with EHPSS.MethodsData collected from medical records included signalment, history, physical examination, clinicopathologic testing, medications, diagnostic imaging, intraoperative findings, perioperative complications, and postoperative clinical outcomes. Long‐term clinical outcome was obtained from a standardized owner interview or medical records.ResultsPerioperative complications were reported in five cats out of 20, including blindness (two cats), ascites (one cat), head pressing (one cat), and seizures and death (one cat). Short‐term clinical outcome was excellent in 14/18 cats, good in 2/18 cats, and poor in 2/18 cats that were available for follow up, and long term clinical outcome was excellent in 15/18, good in 1/18 cats, and poor in 2/18 cats that were available for follow up.ConclusionLong‐term clinical outcome was good or excellent in 16/18 of cats available for follow up. Perioperative complications were reported in five cats.Clinical significanceSurgical attenuation of EHPSS with an ARC can result in resolution of clinical signs and biochemical abnormalities in the majority of cats. The perioperative complication rate for feline patients with EHPSS attenuated with an ARC was lower than reported historically. Seizures may persist in the long term despite normal bile acid stimulation test results, complete blood count, and biochemistry analysis.

“…Splenosystemic shunts are a unique subtype that draw significant parallels to the mesentericorenocaval shunt identified. 13,25 In a retrospective study of 33 afflicted cats, a single vascular communication was identified from the splenic vein and terminating in either the left renal vein or CdVC. 13 The definitive aetiology similarly remains open; Palerme et al hypothesise that these represent congenital shunts with minimal clinical significance, and their identification during investigations of vomiting or inappetence was completely incidental.…”

Case summary A 3-year-old entire female Burmese cat was presented for investigation of intermittent lethargy during gestation followed by persistent hypersalivation and ataxia postpartum. The cat had queened three litters in total, with clinical signs worsening during the most recent lactation period. Mild anaemia (26%), hypoglycaemia (2.4 mmol/l; reference interval [RI] 3.9–8.3 mmol/l) and increased postprandial serum bile acids (74 µmol/l; RI <25 µmol/l) were identified on initial bloodwork. Multiphase contrast-enhanced CT identified a mesentericorenocaval portosystemic shunt; this was attenuated surgically with an ameroid constrictor. Clinical signs resolved after surgery. Follow-up 3 months postoperatively revealed normal pre- and postprandial serum bile acids (2 µmol/l and 3 µmol/l, respectively) with repeat CT identifying evidence of shunt attenuation. The cat continued to be healthy and free of clinical signs 12 months postoperatively. Relevance and novel information Mesentericorenocaval portosystemic shunt morphology has not been previously reported in the cat and should be considered as a differential diagnosis for cats presenting with peripartum onset of malaise, ptyalism or ataxia.
