Subchorionic Hemorrhage: Follow-up
Updated: Jun 23, 2009
Intervention
Bed rest is usually advised for patients with first-trimester bleeding, and serial ultrasonography may be performed as clinically indicated to monitor fetal viability and the size of the hematoma.
Medicolegal Pitfalls
- Isoechoic hematomas should be suspected in cases of first-trimester bleeding with a thickened and heterogeneous placenta.
- Follow-up ultrasonography should be performed as clinically indicated.
