A case of recurrent rupture of the uterus is presented. The patient ha
d a history of left cornual uterine rupture, which was repaired, and s
he was considered to be suitable for a subsequent pregnancy. During th
e subsequent pregnancy, attempts were made to evaluate the condition o
f the uterine scar by ultrasound in order to anticipate threatening ru
pture of the scar. No signs of dehiscence could be detected until the
patient presented with clinical signs. Ultrasound examination revealed
protrusion of the membranes at the fundus uteri. Uterine rupture is a
rare, but hazardous, obstetric complication that can affect both moth
er and child. The possible role of ultrasound in cases of elevated ris
k for uterine rupture is discussed.
