Case of Prenatal Diagnosis of a Fetal Pulmonary Arteriovenous Malformation at Term.

In our case, the malformation was diagnosed prenatally at 40 weeks of gestation, and at the age of 14 days, the malformation was removed combined with a segmentectomy of the sixth segment of the left lung. Preoperative diagnostics focus on 3D-CT reconstruction and detailing of the anatomical variations of all arterial and venous vessels, as evident from our case. Treatment includes surgical removal or a minimally invasive interventional approach through the embolization of the vessel afferent to the malformation.

Macroscopic and histopathologic findings in a laparoschisis model in fetal sheep: comparisons with gastroschisis in human fetuses and implications for prenatal interventions.

Purpose: In order to further define the challenges, minimally invasive fetal surgery will have to overcome human fetuses with gastroschisis. The purpose of this study was to compare macroscopic and histopathologic characteristics of experimental laparoschisis in sheep fetuses with actual cases of gastroschisis from a postmortem series of human fetuses.

Methods: Employing fetoscopy, we created a laparoschisis model in eight fetal sheep between 74 and 92 days of gestation (median 86.

Partial amniotic carbon dioxide insufflation during minimally invasive fetoscopic interventions seems safe for the fetal brain in sheep.

Background: Partial amniotic carbon dioxide insufflation (PACI) during fetoscopic interventions greatly improves visualization of intraamniotic contents. The purpose of this study was to assess any histologically discernable effects from this approach on the fetal brain after long-term survival in sheep.

Methods: Six pregnant ewes between 63 and 92 days of gestation underwent PACI after fetoscopic intraamniotic access.

Maternal complications of fetoscopic laser photocoagulation (FLP) for treatment of twin-twin transfusion syndrome (TTTS).

Aims: Fetoscopic laser photocoagulation (FLP) has become standard therapy for severe twin-twin transfusion syndrome. Data on adverse maternal events are rare. We performed a literature review to obtain data on maternal complications of FLP.
