What is Perigestational sac hemorrhage?
Perigestational hemorrhage (PGH) refers to hemorrhage that occurs around the fetus during the gestational period. The spectrum of hemorrhage includes: chorionic hemorrhage: caused by the separation of the chorion from the endometrium. subchorionic hemorrhage: most common type, occurs between the chorion and endometrium.
Can a Perigestational hemorrhage cause a miscarriage?
Conclusion. Ultrasonographically detected subchorionic hematoma increases the risk of miscarriage in patients with vaginal bleeding and threatened abortion during the first 20 weeks of gestation. However, it does not affect the pregnancy outcome measures of ongoing pregnancies.
Can a subchorionic hematoma come out?
Do subchorionic hematomas go away? Subchorionic hematomas vary in size, from small to large, and smaller bleeds will often clear up on their own without any treatment.
What size is a small subchorionic hemorrhage?
In early pregnancy, a subchorionic hemorrhage is considered small if it is <20% of the size of the sac, medium-sized if it is 20-50% 9, and large if it is >50-66% of the size of the gestational sac 5. Large hematomas by size (>30-50%) and volume (>50 mL) worsen the patient’s prognosis 9.
Does bed rest help subchorionic hemorrhage?
There was no association between duration of vaginal bleeding, hematoma size, or gestational age at diagnosis of subchorionic hematoma and pregnancy outcome. Conclusions: Fewer spontaneous abortions and a higher rate of term pregnancy were noted in the bed-rest group.

A subchorionic hemorrhage may or may not be worrisome, depending on the size and location. What Is a Subchorionic Hemorrhage? A subchorionic hemorrhage, also called a subchorionic hematoma , is bleeding between the amniotic sac (membranes) and the uterine wall.
How big is a subchorionic hemorrhage in early pregnancy?
In early pregnancy, a subchorionic hemorrhage is considered small if it is <20% of the size of the sac, and large if it is >50-66% 5. Treatment and prognosis. Fetal outcome is dependent on the size of the hematoma, maternal age, and gestational age 2. In most cases, the hematoma gradually decreases in size on follow-up.
What causes subchorionic bleeding in the uterus?
Subchorionic bleeding occurs when the placenta detaches from the original site of implantation. These lift apart and form another sac between the placenta and the uterus. The movement and resulting clots are what cause this type of bleeding.
