OBJECTIVE: The objectives of this study are (1) to determine whether there is an association between dogs with splenic hemangiosarcoma (HSA) and the development of premature ventricular contractions (VPCs), (2) to determine if there is a higher likelihood for dogs with ruptured splenic masses to be diagnosed with HSA and to develop VPCs, (3) to determine if the development of VPCs affects median survival times compared to dogs with benign or non-HSA malignant splenic masses.
STUDY DESIGN: Retrospective case series.
ANIMALS: Forty-five dogs.
METHODS: Medical records of dogs undergoing splenectomy were reviewed for signalment, perioperative electrocardiogram (ECG), hematological values, histologic diagnosis, metastasis, and survival times. ECGs were performed preoperatively, intraoperatively, and continuously postoperatively. The presence of VPCs was recorded. The data were evaluated for an association between the development of VPCs and the histologic diagnosis of HSA.
RESULTS: Eighteen out of 45 (40%) dogs were diagnosed with HSA with 13/18 (72%) dogs having VPCs postoperatively (P = .02). Ruptured splenic HSA and VPCs were noted in 13 dogs (P = .73). An association between dogs with and without VPCs diagnosed with HSA and median survival times could not be established.
CONCLUSION: Postoperative VPCs were more likely with splenic HSA. Splenic masses were more likely to be HSA if ruptured but less likely to develop VPCs. Development of VPCs does not affect median survival times.
CLINICAL SIGNIFICANCE: Development of postoperative VPCs may be a potential indicator of HSA, however, this warrants further investigations. Development of VPCs does not have a deleterious effect on survival.
