“…Larger chorioangiomas (>5 cm), particularly when rapidly growing, are associated with negative clinical impact. 8,9 This consensus in literature about the association between the chorioangioma size and its clinical manifestations was replicated in our case.…”

“…10 Although the underlying pathophysiology for these difficulties has not been fully elucidated, a conspicuous role for arteriovenous shunting and sequestration of red blood cells and platelets by tumor have been postulated. [8][9][10][11] This leads to hemolysis, microangiopathic anemia, and reduced oxygen carrying capacity of blood, leading to hydrops. High output heart failure is main reason for neonatal mortality (30-40%).…”

“…Многоводие является патогномоничным симптомом хорионангиомы и развивается в 14-33 % случаев. Существует прямая кор-реляция между размерами, степенью васкуля-ризации опухоли и выраженностью многово-дия [4,9,10]. В свою очередь при выраженном многоводии частым осложнением течения беременности является ее невынашивание.…”

Рlacental chorioangiomas: diagnosis and management

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.

Can ultrasound be helpful in selecting optimal management methods for pregnancies complicated by placental non-trophpblastic tumors?

Placental chorioangioma is the most common subtype of non-trophoblastic placental tumors. Other subtypes are very rare and usually associated with an uneventful course of pregnancy. Most chorioangiomas are small and of no clinical significance. Giant chorioangiomas may be associated with serious fetal and maternal complications. So far, no established ultrasound guidelines are available for the management of placental non-trophoblastic tumors. This may be attributed to the rarity of the disease entity and its different clinical features and complications. In this article, the role of ultrasound findings such as the tumor’s size, vascularity, feeding vessels, amniotic fluid and location of the placenta in the diagnosis, treatment and follow up of these tumors is presented relying on up-todate literature review. Conservative management with serial ultrasound examinations can be an adequate method for monitoring small uncomplicated tumors. Ultrasound-guided procedures such as amnioreduction and cordocentesis can be used for amelioration of complications. Chorioangioma-specific treatment is reserved for complicated cases in the second trimester of pregnancy when prematurity is a matter of concern. Endoscopic laser ablation is indicated when the feeding vessel is superficial and small. Interstitial laser ablation is helpful when the placenta is located in the anterior uterine wall. Ligation of the feeding vessels is preferred when they are large. Alcohol injection should be performed away from the vasculature to prevent toxicity. Microcoils should be inserted as near as possible to the tumor to prevent collateral formation. Ultrasound is also a method of choice for monitoring the effectiveness of these procedures.
