The purpose of this study is to evaluate the efficacy of KARL STORZ curved fetoscope (11508AAK) and its straight version (11506AAK) for laser photocoagulation of placental anastomoses in patients with an anterior placenta and Twin to Twin Transfusion Syndrome (TTTS).
Inclusion Criteria: * pregnancy * The patient fulfills the criteria for laser photocoagulation of placental anastomoses based on the standard of care * fetal diagnosis of twin-to-twin transfusion syndrome * Anterior placenta * The patient provides signed informed consent that details the maternal and fetal risks involved with the procedure Exclusion Criteria: * Contraindication to abdominal surgery, fetoscopic surgery, or general anesthesia * Allergy or previous adverse reaction to a study medication specified in this protocol * The patient does not fulfill the conventional criteria to unde…
The KARLZ STORZ curved scope is used to see the inside of a pregnant person's uterus during minimally invasive surgery, similar to conventional scopes. The curved scope is rounded and thought to help visualize the anterior placenta because of its position on the uterus.
The conventional scopes are regularly used during laser photocoagulation of placental anastomoses.
