A case of spontaneous hemoperitoneum by uterine vessel ruptu
Spontaneous hemoperitoneum during pregnancy is very rare. In most cases, hemoperitoneum is caused by rupture of venous blood vessels. Non-obstetric causes of hemoperitoneum during pregnancy include rupture of the maternal umbilical vein, rupture of the splenic arterial aneurysm, liver rupture, and rupture of liver hemangioma or metastasis. Obstetric causes include uterine scar rupture after corneal pregnancy surgery, rupture of uterine vessels, and uterine rupture due to placenta percreta. Spontaneous rupture of uterine blood vessels is very rare, and the prevalence rate is estimated to be approximately at 1 in 10,000 births. The most common locations were spontaneous rupture of uterine blood vessels occur are broad ligament, the posterior surface of the uterus, and the anterior uterus. Rupture of surface uterine blood vessels is the most common form of hemoperitoneum during pregnancy, particularly during the third trimester. Hemoperitoneum during pregnancy can be treated surgically. Most previously reported cases describe the use of hemostasis after a cesarean section. However, here, we report a pregnant woman with hemoperitoneum caused by spontaneous blood vessel rupture on the uterine surface who was able to deliver a full-term baby because her pregnancy was maintained by successful surgical hemostasis.
