ABSTRACT
Developmental anomalies of the Müllerian duct systems such as the bicornuate uterus are rare globally and hardly do term pregnancies occur in conjunction with these abnormalities. The occurrence of post-dated pregnancy is rarely associated with a bicornuate uterus. We present a 35-year-old un-booked multigravida with post-date pregnancy complicated by breech and intrauterine foetal death (IUFD) in a rudimentary uterine horn. She had caesarean delivery complicated by intractable postpartum haemorrhage (PPH). This together with the risks of poor uterine involution in the postpartum and obstetric outcome in the event that another pregnancy occurs in the same horn subsequently warranted a caesarean hemi-hysterectomy of the rudimentary uterine horn. Uterine bicornuate is an uncommon genital tract anomaly and a rare cause of post-date pregnancy. Postpartum bleeding warranting caesarean hemi-hysterectomy should be anticipated as the pregnant horn may not be responsive to conventional oxytocics.
