Focused ultrasound of the caudal vena cava in dogs with cavitary effusions or congestive heart failure: A prospective, observational study.
<h4>Introduction</h4>Ultrasonographic indices of the inferior vena cava are useful for predicting right heart filling pressures in people.<h4>Objectives</h4>To determine whether ultrasonographic indices of caudal vena cava (CVC) differ between dogs with right-sided CHF (R-CHF...
