Large number of medical information, placental abruption, with the following factors:
maternal blood vessels. Pregnant women with pregnancy-induced hypertension, chronic hypertension, chronic kidney disease and other diseases, these diseases can cause the end of decidual arteries spasm, infarction, resulting in necrosis of distal capillaries, causing bleeding. Blood flow to the bottom between the decidua and placenta, placental hematoma formation, leading to placental separation. Increased bleeding, hematoma size has been expanded, also expanded area of placental separation. Maternal placental vascular disease is the most important reason, accounting for about half the rate.
abdominal injury. Pregnant women, such as by the impact of abdominal trauma, can cause the end of decidual blood vessels rupture, hemorrhage, leading to placental abruption.
premature rupture of membranes. Premature rupture of membranes, amniotic fluid flowing too fast, too, could dip intrauterine pressure, uterine volume suddenly reduced, causing dislocation between the uterine wall and placenta, stripping, damage small blood vessels, causing bleeding, also contributed to the early placenta stripping one of the reasons. Late pregnancy with vaginal intercourse or when prone to premature rupture of membranes. Twin birth, first child after delivery, or rupture of the amniotic fluid of pregnant women too much water the sheep, amniotic fluid out too fast, but also prone to placental abrupti


on.
uterine vein blood pressure. Late pregnancy or childbirth, maternal supine position for a long time, great oppression of the inferior vena cava uterus, resulting in venous disorders, pelvic veins and uterine venous stasis, venous pressure continues to rise, resulting in excessive decidual vein congestion, rupture bleeding, leading to placental separation.
In either cause the end of decidual vessel rupture, hemorrhage, can accumulate in the blood between the end of decidua and placenta, the formation of the placenta after the hematoma. With the increasing bleeding, hematoma cavity pressure increased, prompting the placental tissue around the hematoma been stripped from the uterine wall, bleeding. If, and to break through the placenta to reach the edge of hematoma, hematoma washed the blood from the open edge of the placenta, the cervix and vagina out of the body, known as the dominant stripping. As the blood to flow to the body, so that the pressure drop hematoma cavity, hematoma area is no longer expanding, no longer continue to peel the placenta, therefore, the condition often lighter. If, after the hematoma failed to reach the placenta and the placenta broke through the edge of the blood can not flow, is called recessive peel. Recessive stripping patients, blood in the placenta after the increase in hematoma cavity, intrauterine pressure increased, forcing the hematoma cavity immersed in myometrial blood, causing separation and degeneration of uterine muscle fibers, the surface of the uterus showing purple blue, medically known as uterine placenta Stroke. Another serious consequence of placental abruption is a lot of damage to the release of decidual thromboplastin into the maternal circulation, causing coagulation disorders, blood was streaming out of the bloody-like, no blood clot, medically known as disseminated intravascular coagulation (DIC). Occurrence of DIC can often lead to refractory maternal hemorrhage, maternal death often result. Thus, placental abruption is a serious consequence of high mortality and obstetric complications.
Placental abruption, placenta previa is the second, the second antenatal vaginal bleeding caused by complications of pregnancy. Although the same prenatal bleeding, but with features. Placenta previa is bleeding without abdominal pain, abdominal examination a soft, no tenderness, vaginal bleeding and placental abruption is often accompanied by severe abdominal pain, attached to the posterior wall of the uterus when the placenta as early as stripping, usually manifested low back pain or abdominal back pain. Examination revealed the uterus as hard as plate, there is tenderness, and with increased bleeding, placental hematoma is increasing, the end of the uterus will gradually increase. Therefore, pregnant women suspected of placental abruption, a hospital, the doctor will house the abdominal wall in pregnant women the use of color strokes at the end of a line from time to time observe the fundus has exceeded the number of crossed and beyond, to estimate the extent of bleeding after the placenta and the development of the disease. Time to do B-ultrasound in early diagnosis and treatment.
After diagnosis of placental abruption should be in time, too long to wait, observe, could easily lead to placental separation are continuously expanding, the placenta continues to increase after the hematoma, leading to stroke the uterus, making the disease more serious, more complex. Therefore, early diagnosis and timely treatment is to reduce the loss of good consequences for the key.
