Uterine dehiscence in early second trimester.

Background: The diagnosis of uterine dehiscence in the early second trimester by ultrasonography is rare and its effect on pregnancy outcome is unclear.

Case: An asymptomatic woman presented for anatomy survey in the 19th week of pregnancy. Uterine dehiscence at the site of previous hysterotomy was diagnosed by ultrasound scan. She was admitted to the hospital for expectant management and eventually opted for termination of pregnancy in the 22nd week of pregnancy. Termination was performed by classical hysterotomy without any complications.

Conclusion: Given the increasing cesarean delivery rate and improvements in ultrasound technology, obstetricians should expect to face the management dilemma of antenatally diagnosed uterine dehiscence. The risks of expectant management compared with termination remain theoretical, and timing of delivery and methods of termination are important questions to consider.
