What is placental abruption

summary

The gestation of a baby is closely related to the placenta formed in the womb of a woman. Only a placenta with no health problems can make the baby more healthy. For placental abruption, it will naturally affect the development of the fetus. Now let's talk about what is placental abruption.

What is placental abruption

First: late pregnancy or parturient, maternal supine position for a long time, can occur supine hypotension syndrome. At this time, because the huge pregnancy uterus oppresses the inferior vena cava, the amount of return blood is reduced, and the blood pressure is decreased, but the uterine vein is congested, and the venous pressure is increased, which leads to congestion or rupture of decidual vein bed, resulting in partial or total placental detachment from the uterine wall.

Second: placental abruption pregnant women complicated with gestational hypertension, kidney disease, especially systemic vascular disease in the majority. When the basilar decidual spiral arterioles spasm or harden, the distal capillaries are ischemic and necrotic, resulting in rupture and bleeding. The blood flows to the basilar decidual layer to form a hematoma, resulting in the separation of the placenta from the uterine wall.

Third: after 20 weeks of pregnancy or delivery period, the normal placental position before the delivery of the fetus, part or all from the uterine wall dissection, known as placental abruption. The main symptoms of mild placental abruption are vaginal bleeding, the amount of bleeding is generally more, the color is dark red, may be accompanied by mild abdominal pain or abdominal pain is not obvious, anemia signs are not significant.

matters needing attention

The formation of placental abruption is inseparable from women's activities. During pregnancy, people should not drink and smoke, and should pay attention to the fact that individuals can not exercise violently. In addition, pregnant women should regularly go to the hospital for prenatal examination, so as to find out the fetal development more timely and achieve early detection and early treatment.
