Klippel-Trenaunay-Weber syndrome is a rare congenital deep-vein malfor
mation. Pregnancy in patients with this syndrome is rare and only a fe
w cases have been reported. Known obstetrical risks in pregnant patien
ts with this syndrome include bleeding from angiomata in the genitalia
, and coagulation disturbances. We present a 31 year old woman with th
is syndrome who, on two occasions, delivered small-for-gestational-age
neonates. This may have been due to placental insufficiency caused by
angiomatosis related to the syndrome.
