Transeverse uterine rupture. Uterine rupture is when the muscular wall of the uterus tears during pregnancy or childbirth. [3] Symptoms, while classically including increased pain, vaginal bleeding, or a change in contractions, are not always present. [1] [2] Disability or death of the mother or baby may result. [1] [3]
In an incomplete rupture, the peritoneum is still intact. With a complete rupture, the contents of the uterus may spill into the peritoneal cavity or the broad ligament. A uterine rupture is a life-threatening event for both mother and baby as it typically results in severe hemorrhage and can cause perinatal asphyxia.
In 2015 about 6.5 million cases of obstructed labour or uterine rupture occurred. [5] This resulted in 23,000 maternal deaths down from 29,000 deaths in 1990 (about 8% of all deaths related to pregnancy). [2] [6] [9] It is also one of the leading causes of stillbirth. [10] Most deaths due to this condition occur in the developing world. [1]
Along with placenta previa and uterine rupture it is one of the most common causes of vaginal bleeding in the later part of pregnancy. [6] Placental abruption is the reason for about 15% of infant deaths around the time of birth. [2] The condition was described at least as early as 1664. [7]
[55] [56] Furthermore, prior cesarean delivery is one of the most common risk factors for placenta accreta, due to the presence of a uterine scar leading to abnormal decidualization of the placenta. [57] Due to abnormal adherence of the placenta to the uterine wall, cesarean delivery is often indicated, as well as cesarean hysterectomy. [54]
A caesarean section leaves a scar in the wall of the uterus which is considered weaker than the normal uterine wall. A VBAC carries a risk of uterine rupture of 22–74/10,000. Slightly lower risk of uterine rupture in women undergoing ERCS (i.e. a section before the onset of labour). [1]
She experienced a uterine rupture while eight months pregnant and was rushed to the hospital, where doctors discharged her instead of keeping her for observation. She returned home, unaware that ...
Causes of vaginal bleeding early in pregnancy include miscarriage (including inevitable, incomplete, or complete abortion), embryo implantation and growth outside the uterus (ectopic pregnancy), and placenta attachment at the bottom of the uterus over the cervix (placenta previa), all of which can cause significant bleeding.
