Fetoscopic laser therapy for TTTS performed percutaneously
before 26 weeks of gestation is a minimally
invasive treatment with few maternal complications,
with premature rupture of membranes becoming
the main source of neonatal complications [17].
It has been recognized that laser surgery for TTTS
should be available in fetal medicine units that
are managing at least 20 cases per year [13].
