Pulmonary thromboembolism associated with caudal vena caval thrombosis in a heifer

Abstract

A 2-year-old heifer from a herd of approximately 300 Angus crossbred heifers kept at range was evaluated because
of a 3-day history of hemoptysis (Fig. 1). The cow stopped eating and spent long periods standing in a pond away from the
herd. Anti-inflammatory and antibiotic treatment was initiated with no avail. The heifer was euthanized and autopsied on the
fourth day after the onset of clinical signs.
