Konno et al: Risk factors for complications associated with canine hepatic mass resection: A study of 96 cases
Veterinary Surgery 1, 2026

🔍 Key Findings

  • Postoperative complications occurred in 17.7% of dogs undergoing hepatic mass resection; mortality was 6.3%
  • Shorter corrected distance from hepatic mass to CVC (per 0.1 cm/kg decrease) was significantly associated with increased complications (OR: 0.666; p = .017)
  • Presence of underlying disease increased complication risk (OR: 2.703; p = .007)
  • Intraoperative hypotension was a strong predictor of complications (OR: 3.589; p = .019)
  • Surgical time was borderline significant in multivariable models (OR: 1.011 per min; p = .052)
  • Liver lobe location (left, central, right) was not significantly associated with complications
  • Prothrombin time (PT) correlated with complication risk in univariable analysis but was not consistently significant in multivariable models
  • CT evaluation of mass proximity to the CVC is a useful preoperative predictor of complication risk

Multiple Choice Questions on this study

In Konno 2026 et al., on hepatic mass resection risks, what was the significance of the corrected distance from the mass to the CVC?

A. It predicted hemorrhagic complications only
B. It was not associated with outcomes
C. It was a key risk factor for severe complications
D. Only relevant in central lobe tumors
E. It was used to select the lobectomy technique

Answer: It was a key risk factor for severe complications

Explanation: Corrected distance was significantly associated with complications (OR: 0.666 per 0.1 cm/kg; p = .017).
