Feline aortic thromboembolism with and without congestive heart failure did not exhibit hypercoagulability using a novel viscoelastic coagulation monitor.

OBJECTIVE: To demonstrate hypercoagulability with a benchtop viscoelastic monitor in cats with congestive heart failure (CHF) and/or aortic thromboembolism (ATE) compared to controls. METHODS: 97 cats were enrolled throughout this prospective observational cohort study from September 2022 through October 2023. Cats were grouped by diagnosis of CHF, ATE, ATE plus CHF, or controls. Enrollment required diagnosis of heart disease and no previous antithrombotic therapy. The results of viscoelastic testing with the benchtop viscoelastic coagulation monitor (VCM Vet [VCM]; Entegrion) were compared between groups using factorial analysis of variance. RESULTS: Cats with heart disease had significantly higher clot times when compared to controls (control: mean, 285.3 [SD, 172.6]; CHF: mean, 391.7 [SD, 106.8]; ATE: mean, 415.9 [SD, 109.2]; and ATE plus CHF: mean, 368.6 [SD, 232.6]). Heart disease cats were noted to have significantly lower 45-minute lysis index values (control: median, 100 [range, 93 to 100]; CHF: median, 99 [range, 89 to 100]; ATE: median, 98 [range, 88 to 100]; and ATE plus CHF: range, 98 [91 to 100]). Age was a covariate to this variable, and when applied to analysis, statistical significance was lost. No significant difference in any other variables were noted. CLINICAL RELEVANCE: The hypercoagulability of ATE and CHF cats was not detected by the VCM. Further research with other coagulation monitors is required in this population.

Successful surgical management of pancreatic torsion in a 3-month-old Bernese Mountain dog without evidence of long-term pancreatic dysfunction.

To describe the clinical presentation, diagnosis, perioperative management and the short- and long-term outcomes of a dog diagnosed with pancreatic torsion. A 3-month-old female intact Bernese Mountain dog presented for an acute onset of vomiting, anorexia and abdominal pain. Abdominal ultrasonography showed a hypoechoic mass effect cranial to the stomach. A pancreatic torsion was diagnosed during exploratory laparotomy and treated with partial pancreatectomy. Histopathology confirmed pancreatic torsion. The patient recovered uneventfully and pancreatic function and inflammation testing that was performed 14 months postoperatively showed no evidence of ongoing dysfunction. This is the first report that demonstrates long-term follow-up with pancreatic function testing in a patient who had a partial pancreatectomy due to pancreatic torsion. There was no evidence of long-term pancreatic dysfunction due to partial pancreatectomy secondary to pancreatic torsion. Additionally, this is the youngest patient with pancreatic torsion to be described in the veterinary literature.
