subchorionic

It also may be called a subchorionic hematoma.

Most patients with a small subchorionic hematoma are asymptomatic.

Subchorionic hematomas, the most common type, are between the chorion and endometrium.

A subchorionic hemorrhage is bleeding under one of the membranes (chorion) that surrounds the embryo.

In 1892 he described a rare condition now known as "Breus' mole", defined as a massive subchorionic hematoma of the placenta that takes place in a stillbirth.

Whilst bed rest has been advocated in the past to help ensure that a threatened pregnancy might continue, and in one study possibly helped when small subchorionic hematoma had been found on ultrasound scans, the prevailing opinion is that this is of no proven benefit.
