Abstract
Objective: Fetoscopic laser photocoagulation of vascular anastomoses (FLP) is the essential choice in twin-twin transfusion syndrome (TTTS). We proposed that the modified sequential selective laser photocoagulation of communicating vessels (modified SQLPCV) to clarify the perinatal outcomes in TTTS.
Methods: The modified SQLPCV was designed with the following order: 1, artery-to-artery anastomoses; 2, venous-to-venous anastomoses; 3, artery-to-venous anastomoses from donor to recipient; and 4, artery-to-venous anastomoses from recipient to donor. The perinatal outcomes were present in TTTS patients who underwent the modified SQLPCV.
Results: A total of 203 women underwent modified SQLPCV. The mean pregnancy prolongation period was 83 days, and the mean gestational age at delivery was 33 weeks (range 23–40 weeks). There was a significantly lower rate of recipient fetal demise than donor fetal demise (4% vs. 13%; p < .01). The survival rate of zero and one were respectively 6% (13/203) and 19% (39/203). Two survivors were seen in 74% (151/203), and at least one survivor in 94% (190/203). Univariate and multivariate analysis showed that abnormal fetal Doppler measurements in donor were correlated with donor demise after surgery.
Conclusions: The modified SQLPCV represents satisfactory outcomes for fetuses complicating with TTTS.
