AIM: Iatrogenic premature rupture of membrane (PROM) is one of the major complications related to fetoscopic laser photocoagulation (FLP) for twin-twin transfusion syndrome (TTTS). However, amniotic fluid leakage (AFL) sometimes spontaneously disappears. This study evaluated the incidence and clinical characteristics of transient AFL after FLP.
METHODS: We retrospectively reviewed pregnancies that underwent FLP for TTTS at a single center. Patients with apparent AFL within 2 weeks after FLP were divided into two groups: transient AFL, defined by the disappearance of fluid leakage within a week; and PROM, if AFL persisted continuously for more than a week or premature birth occurred, including miscarriage, within a week of the first symptom of AFL.
RESULTS: Among 201 monochorionic twin pregnancies that underwent FLP during the study period, nine patients (4.5%) were diagnosed with AFL within a week after FLP. Four patients (2.0%) were classified as transient AFL and five as PROM. Median gestational age at FLP was not significantly different between the groups; operative time in the PROM group was significantly longer (P = 0.01). The surgery to delivery interval and median gestational age at delivery were greater in the transient AFL group (87.8 vs 17.6 days, P = 0.01; 32.5 vs 23.6 weeks, P = 0.01, respectively).
CONCLUSIONS: The incidence of transient AFL after FLP was 2%. Perinatal outcomes of transient AFL might be better than that of PROM.
