Abstract
Objective
The purpose of this study was to evaluate the incidence of complications after selective fetoscopic laser photocoagulation for twin-twin transfusion syndrome (TTTS).
Study Design
One hundred fifty-two cases of TTTS were treated with selective fetoscopic laser photocoagulation from 2005-2008. Complications were TTTS recurrence, amniotic band syndrome, iatrogenic monoamnionicity, and twin anemia-polycythemia sequence. Data were placed in the following categories: no complications; early complications ≤7 days; late complications >7 days; both early and late complications.
Results
The incidence of early, late, and both early and late complications was 31%, 39%, and 10%. Complications included 2 cases (1.3%) of monoamnionicity, 3 cases (2.0%) of recurrent TTTS, 3 cases (2.0%) of twin anemia-polycythemia sequence, and 5 cases (3.3%) of amniotic band syndrome. Cases with TTTS with early complications had a lower number of superficial arteriovenous vascular anastomoses and 1 or both fetus survival (70.2% vs 96.7%; P < .001), compared with no complications. Fetal survival was 238 of 307 cases (77.5%), with 1 or both twins surviving in 134 of 152 (88%) of pregnancies.
Conclusion
The incidence of early, late, and both early and late complications was 31%, 39%, and 10%, respectively. Close postoperative surveillance is important.
