Abstract
A 20-month-old miniature mixed-breed heifer weighing 200 kg was presented with a history of dysphagia, sialorrhea and dyspnea after being fed with food residues. At home it was treated with intravenous hydration, antibiotic combination, diuretics and AINEs. Additionally, one failed passage of oro-ruminal tube and several ruminal trocarizations were performed. At clinical examination the animal showed signs compatible with digestive obstruction, severe dyspnea and shock. Complete blood count showed leukocytosis with neutrophilia, left shift and lymphocytosis. Serum chemistry tests showed hyperlactatemia, hypokalemia, hypocalcemia, hyperglycemia and azotemia. Acid-base analysis indicated severe metabolic acidosis and respiratory alkalosis. Esophagoscopy was performed, during which the patient went into shock and died. In necropsy a complete middle third esophageal obstruction with rupture by a carrot was identified.
Highlights
Esophageal disorders are relatively uncommon in large animals (HASKELL 2008; MARZOK et al, 2015)
Esophageal obstruction (EO) is considered an emergency and is fatally associated when the eructation of ruminal gases is impaired and severe free-gas bloat develops (HAVEN 1990; DIVERS; PEEK 2008; VISHWANATHA et al, 2012; MARZOK et al, 2015), which may be life threatening if not relieved in time (HAVEN 1990; MARZOK et al, 2015)
In bovine veterinary practice, EO caused by foreign objects is considered one of the most important emergency conditions, because it may be life threatening if not relieved in time
Summary
Esophageal disorders are relatively uncommon in large animals (HASKELL 2008; MARZOK et al, 2015). Esophageal rupture (ER) is most frequently associated with foreign body obstruction (HAVEN 1990).
