Abstract:
A sow of 190 kg weight suddenly died, one day before due to delivery, though seeming to be quite healthy a few hours previously. Pathomorphological investigation revealed a 11 cm wide gap in the diaphragma in the area of the hiatus oesophageus with an eventratio diaphragmatica simplex incarcerata. The pathogenesis is suggested to be a widening of an inborn small gap in the diaphragma through the increase of intraabdominal pressure due to pregnancy and beginning labour.
