Korábbi kezelés

• Participation in another intervention study that influences maternal and fetal morbidity and mortality or participation in this trial in a previous pregnancy

Más betegség

• History of natural rubber latex allergy
• Maternal contraindication to fetoscopic surgery or severe maternal medical condition in pregnancy
• History of incompetent cervix with or without cerclage
• Maternal HIV, Hepatitis-B, Hepatitis-C status positive because of the increased risk of transmission to the fetus during maternal-fetal surgery. If the patient's HIV or Hepatitis status is unknown, the patient must be tested and found to have negative results before enrollment Uterine anomaly such as large or multiple fibroids or mullerian duct abnormality

Egyéb
