The objective of this study is to report the use of thromboelastography as a diagnostic tool for the hyperfibrinolytic phase of disseminated intravascular coagulopathy in a dog with metastatic haemangiosarcoma. We established a cytological (i.e. fine needle aspirate) and histopathological (i.e. excisional surgical biopsy) diagnosis of haemangiosarcoma in a 10-year-old male castrated Bichon Frise with multiple dark purple dermoepidermal nodules on the ventral abdomen and medial stifle areas, multiple small pulmonary nodules and a solitary liver mass. The dog was treated with chemotherapy (AC protocol). ⋯ Results of the conventional haemostasis tests supported those obtained on thromboelastography. Humane euthanasia was performed because of poor prognosis and progressive disease, making further follow-up unavailable. As demonstrated in this case report, thromboelastography was found to be a helpful diagnostic tool for the diagnosis and monitoring of the hyperfibrinolytic phases of disseminated intravascular coagulopathy.

To investigate relationships between central venous oxygen saturation (ScvO(2)) and survival to hospital discharge in dogs. Central venous oxygen saturation is an accessible measure of the balance between systemic oxygen delivery and consumption. ⋯ Central venous oxygen saturation was a strong mortality predictor. Further work is needed to determine if therapy targeting central venous oxygen saturation can reduce mortality in canine intensive care unit patients.

To determine the outcome, independent predictors of cardiac death, and the Doppler-derived pressure gradient cut-off for predicting cardiac death in dogs with pulmonic stenosis, with or without tricuspid regurgitation, that do not undergo balloon valvuloplasty or valve surgery. ⋯ There is an increased probability of cardiac death in those cases which have a pulmonary pressure gradient greater than 60 mmHg and tricuspid regurgitation, though the effect of severity of tricuspid regurgitation on outcome was not measurable because of small sample sizes. These animals might benefit from intervention.
