Рlacental chorioangiomas: diagnosis and management

Abstract

Four cases of pregnancies with nontrophoblastic placental tumor – chorioangioma are presented in this article. Clinical symptoms depend on tumors size, vascularisation and histological types (angiomatoid, cellular and degenerative). Small tumors with poor vascularisation are essentially asymptomatic. Large ones can act as peripheral arteriovenosus shunts resulting in fetal functional disorders (polycythemia, hypervolemia, ventriculomegaly) associated with acute polyhydramnion, premature labor, maternal and neonatal complications. The role of ultrasound and color Doppler examinations, invasive procedures (amniocentesis) in the diagnosis of chorioangioma and management of such pregnancies are discussed.
