If the ultrasound reveals a hypotonic gestational sac, it may be caused by embryonic dysplasia, and a comprehensive analysis is recommended in conjunction with blood HCG and progesterone tests. In most cases, termination of pregnancy is more likely, and it is rare to continue the pregnancy to full term delivery. The deformation of the gestational sac may be caused by the early cessation of the embryo’s development if the tension of the sac itself is not good. Therefore, it is recommended to combine the blood HCG and progesterone tests to understand whether the pregnancy should be terminated in time, and it is also recommended that if the pregnancy needs to be terminated, routine blood tests and coagulation time tests should be done beforehand, mainly to exclude the possibility of coagulation dysfunction before the pregnancy is terminated clinically.
