Clinical features, treatment and outcome of 15 horses with penetrating
thoracic wounds are described. The most common cause of trauma was co
llision with an object (10 horses). Concurrent clinical findings inclu
ded subcutaneous emphysema (12 horses), pneumothorax (12 horses), haem
othorax (5 horses) and pneumomediastinum (6 horses). Axillary wounds w
ere present in 5 horses. Foreign bodies were identified and removed fr
om 2 horses. Wounds were sutured (6 horses) or packed (7 horses). Air
was evacuated from the pleural cavities of 11 horses. Eleven horses (7
3%) were discharged from the hospital. All horses subjected to euthana
sia had severe trauma to structures outside the thoracic cavity includ
ing perforation of the colon (2 horses), renal trauma (1 horse) and a
luxated thoracolumbar vertebra (1 horse). From this study, it can be c
oncluded that 1) the prognosis for horses with penetrating thoracic wo
unds, without extrathoracic injury, is favourable; 2) a thorough evalu
ation including the abdominal cavity should be performed and 3) horses
with axillary wounds should he monitored closely for respiratory dist
ress until the wound has completely healed.
