Incidence and impact of perioperative complications in 175 fetoscopy-guided laser coagulations of chorionic plate anastomoses in fetofetal transfusion syndrome before 26 weeks of gestation
Received 1 March 2005; received in revised form 13 June 2005; accepted 30 June 2005.
Objective
The purpose of this study was to evaluate the perioperative complications in fetoscopy-guided laser therapy in fetofetal transfusion syndrome.
Study design
Details of fetofetal transfusion syndrome cases who were delivered between 1999 and 2004 in a single center were reviewed retrospectively.
Results
One hundred seventy-five procedures were performed percutaneously with the use of local anesthesia. Survival at 6 months of at least 1, 1, and 2 babies was 73%, 38%, and 35%, respectively. Placental abruption and miscarriage was diagnosed in 3 and 12 cases, respectively. Premature rupture of membranes occurred in 49 cases (28%) and including 12, 29, and 46 cases that occurred before 24, 28, and 34 weeks of gestation, respectively. The entry of the trocar was transplacental in 48 cases (27%), but it was not associated with miscarriage (P=.26), premature rupture of membranes (P=.58), or placental abruption (P=.37).
Conclusion
Fetoscopic laser treatment of fetofetal transfusion syndrome can be performed percutaneously with local anesthesia without significant maternal morbidity. Transplacental entry was not associated with premature rupture of membranes or miscarriage.
