Can placental abruption be detected by B ultrasound

summary

In the late stage of delivery, placental abruption is often occurred, accompanied by back pain, pain and other symptoms. Let's take a look at placental abruption. Can B ultrasound check it out.

Can placental abruption be detected by B ultrasound

First of all: placental abruption can be detected by B ultrasound. B-mode ultrasonography can determine whether there is placental abruption and estimate the size of the exfoliative surface in suspected and mild patients. If there is a retroplacental hematoma, the ultrasound image shows that there is a liquid dark area between the placenta and the uterine wall, and the boundary is not clear. It is helpful for suspicious and light cases. In addition to the liquid dark area between the placenta and the uterine wall, the light spot reflection (hematoma organization), the protrusion of placental villous plate into the amniotic cavity and the fetal state (with or without fetal movement and fetal heart beat) can also be seen in the dark area.

Secondly: laboratory examination mainly to understand the degree of anemia and coagulation function. Blood routine examination to understand the degree of anemia; urine routine to understand renal function and urinary protein. Severe placental abruption may be complicated with DIC, and relevant laboratory tests should be carried out, including DIC screening test (such as platelet count, prothrombin time, fibrinogen determination and 3P test) and fibrinolysis diagnosis test (such as fi test, namely FDP immune test, thrombin time and euglobulin lysis time, etc.).

Finally: the diagnosis is mainly based on the history, clinical symptoms and signs. Because the symptoms and signs of mild placental abruption are not typical, the diagnosis is often difficult. It should be carefully observed and analyzed, and determined by B-mode ultrasound. The symptoms and signs of severe placental abruption are typical, and the diagnosis is not difficult. At the same time, the severity of severe placental abruption should be judged. If necessary, the above laboratory tests should be carried out to determine whether there are complications such as coagulation dysfunction and renal failure, so as to formulate a reasonable treatment plan.

matters needing attention

Pregnancy induced hypertension syndrome is easy to occur in the second and third trimester of pregnancy. Once pregnant women have symptoms of hypertension, edema and proteinuria, they should actively go to the hospital for early treatment. Pregnant women should pay attention to their daily activities and don't go to crowded places.
