Abdominal Intercostal Hernia in a Cat (Felis Domestica).

ABSTRACT

A 2-month-old entire female domestic short-hair cat (Felis domestica) with no history of trauma was presented for assessment of a swelling on the left thoracic wall. Palpation revealed a large, painless, reducible swelling between the tenth and eleventh ribs on the left side. Radiograph demonstrated dorsal displacement of the abdominal viscera through the tenth intercostal space. An abdominal ultrasound examination confirmed the displacement of stomach and spleen through tenth intercostal space. Surgical correction of the herniated contents was undertaken via intercostal celiotomy. An acellular dermal matrix scaffold, prepared from deceased donor caprine-skin upon treatment with 0.25% trypsin in 4 mol/L NaCl for 8 hours followed by 2% sodium dodecyl sulfate for 48 hours, was used to repair a 3 cm wide intercostal defect present between the tenth and eleventh ribs. Recovery was uncomplicated and the cat was asymptomatic till follow-up period of 26-month after surgery. Congenital intercostal hernia in a cat is being reported, which, to our knowledge, is the first report of its kind.
