Summary
Large placental chorioangiomas, rare vascular tumors over 4 cm, can cause severe fetal and maternal complications. Ultrasound and Doppler are key for diagnosis, with limited but evolving therapeutic options available.
Area of Science:
- Obstetrics and Gynecology
- Fetal Medicine
- Diagnostic Imaging
Background:
- Placental chorioangiomas are rare, non-trophoblastic vascular tumors exceeding 4 cm in diameter.
- Incidence ranges from 1 in 3,500 to 1 in 9,000 births.
- This study reviews ultrasonographic features, maternal/fetal complications, and therapeutic strategies.
Observation:
- Chorioangiomas typically appear as well-defined, hypoechoic areas on ultrasound.
- Color Doppler confirms the vascular nature and can reveal arterio-venous shunting.
- These shunts can lead to fetal growth restriction and intrauterine fetal demise.
Findings:
- Fetal complications include anemia and microangiopathic thrombocytopenia.
- Maternal complications encompass hydramnios, placental abruption, and premature membrane rupture.
- Therapeutic interventions are limited, with options like fetal blood transfusion and tumor devascularization techniques.
Implications:
- Early and accurate diagnosis via ultrasound is crucial for managing chorioangiomas.
- Understanding the pathophysiology of complications guides clinical management.
- Further research into effective therapeutic interventions is warranted to improve outcomes.

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
