80% of embryo chromosome abnormalities will stop in the eighth week, chromosome abnormalities will generally lead to fetal development, is often said that embryo arrest. Although there are many reasons for embryo arrest, but more than 80% of embryo arrest, mostly due to fetal chromosome abnormalities caused by coagulation and immune factors. But the most common or chromosome abnormalities, general embryo arrest more common clinical manifestations are early pregnancy abdominal pain, vaginal bleeding. 80% of embryo and fetal arrest occurs at about eight weeks. After B ultrasound and blood HCG monitoring, fetal heart fluctuation can be found, embryo and fetal arrest can be found in time, chromosome abnormalities, maternal conditions and environmental factors can be excluded, and pregnancy can be terminated as soon as possible.
