Coagulation of the feeding vessels was attempted with laser energy, and the operation was completed with amniodrainage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The feeding vessels were successfully coagulated in one case, resulting in a term delivery. Histopathologic examination of the placenta confirmed a capillary chorioangioma with extensive necrosis. There were intraoperative complications in the other two cases, including bleeding at the site of coagulation requiring intrauterine transfusion in one, and incomplete vascular ablation in the other. In the former case the infant was born prematurely and developed chronic renal insufficiency. In the latter, the fetus died within the first week of the surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There are limited interventions available for the management of large, symptomatic placental chorioangiomas. Although they can be treated with endoscopic laser coagulation of the feeding vessels, fetal bleeding, exsanguination, and death are potential complications of the procedure; therefore, this technique should be used with caution. The role of this treatment modality in the early devascularization of placental chorioangiomas prior to the development of significant complications warrants consideration.
