Spontaneous second trimester rupture of a previous caesarean section scar: A case report.

Spontaneous uterine rupture before the onset of labour is rare in pregnancy especially before the third trimester. It is life threatening with devastating consequences to the mother and fetus. We report a case of spontaneous second trimester uterine rupture in a multipara with a previous uterine scar with the aim of creating awareness and sharing the challenges in diagnosis and management of this unusual complication of pregnancy. A 34-year-old woman with two previous deliveries presented at 16 weeks gestation with abdominal pain and vaginal bleeding of one day duration. At presentation, she was pale and in shock. There was generalized abdominal tenderness with guarding and rebound tenderness. At laparotomy, there was uterine rupture involving the lower segment with right lateral upward extension which was repaired. She remained stable at the follow up visit. In conclusion, Spontaneous uterine rupture of a previous caesarean section scar in the second trimester is rare. The diagnosis should be considered in a woman with previous caesarean section who experience an acute abdomen in the second trimester of pregnancy.
