When only the margin of the placenta is separated, it is called a marginal subchorionic hematoma (Fig. 1A,1B,1C). When the bleeding is behind the placenta, it is termed a retroplacental bleed. The term “abruption” (abruptio placentae) is typically reserved for premature placental separation occurring after 20 weeks.

Is a subchorionic hematoma a placental abruption?

Condition Characterized by Partial Placental Detachment

Sometimes bleeding is a symptom of a fairly common type of blood clot called a subchorionic hematoma (also known as subchorionic hemorrhage).

Can SCH cause placental abruption?

Unlike the risk of pregnancy loss, the risk of placental abruption in women with SCH is well established. When SCH is present, the risk of placental abruption increases from 0.6% to 3.6% (aOR = 2.6, 95% CI 1.8 – 3.7) [4]. This finding is echoed by several other studies [5,13,20].

What is the other name for placental abruption?

Placental abruption (abruptio placentae) is an uncommon yet serious complication of pregnancy.

What are the two types of placental abruption?

There are two main types of placental abruption:

• Revealed - bleeding tracks down from the site of placental separation and drains through the cervix. This results in vaginal bleeding.
• Concealed - the bleeding remains within the uterus, and typically forms a clot retroplacentally.

Can Subchorionic hemorrhage cause birth defects?

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.
