[Uterine rupture. Reflections apropos of a spontaneous case in mid-pregnancy]

A case of spontaneous uterine rupture is reported occurring in the midtrimester of pregnancy in a patient who had benign signs of tuberous sclerosis. There was no placenta increta but the myometrial thickness, at the site of placental insertion, was only 160 microns. This finding is discussed. On this occasion, the authors review the aetiology and signs of uterine rupture, its treatment and prevention, especially before the third trimester of pregnancy.
