title: Uterine prolapse with an interesting vascular anomaly in a cheetah: a case report.
abstract: A 5-year-old cheetah suffered a complete prolapse of the left uterine horn after the birth of her second litter. Two attempts to reduce the prolapse transvaginally failed. The animal was hospitalized 13 days after the prolapse first occurred, and an ovariohysterectomy was performed to resolve the prolapse. The prolapsed uterine horn had been mutilated: its tip, together with the ipsilateral ovary was absent. Laparotomy revealed no sign of recent or past hemorrhage or adhesions, or any signs of the left ovarian artery or left ovarian vein in the remnants of the left mesovarium. A large vein crossed the uterine body from the left uterine horn to join the right uterine vein, presumably serving as the only route of venous drainage for the prolapsed uterine horn. A possible cause for the prolapse is excessive mobility of the uterus due to prior rupture of its mesial support. The animal died 24 days after surgery due to chronic renal failure, as a result of severe renal amyloidosis.
