Abstract
Medical and surgical management of a foetopelvic dystocia in an African lioness (Panthera leo) and the post-operative complications are reported. A caesarean section was performed to extract an oversize foetus blocked at the cervical canal; the lioness died 36h after surgery. At necropsy, an abdominal effusion with sero-haemorrhagic fluid was observed, along with a fibrinopurulent exudate adhered to the serosal surfaces of the pelvic and abdominal cavities. In addition, the pelvic symphysis was not cartilaginous, but formed a firm and rigid joint between the pubis and ischium of each hip. The macroscopic and microscopic findings confirmed the presence of metritis, vaginitis and peritonitis. Dystocia may be caused by the premature ossification of the pelvic symphysis, reducing the dimensions of the pelvic cavity.
