This review examines the preferred route of delivery in accordance with neo
natal and maternal outcome of three high risk pregnancy conditions: multipl
e pregnancy; delivery after cesarean section; and delivery of infants with
macrosomia to mothers with gestational diabetes mellitus. The most common f
eature of all these conditions is the lack of information, based on large p
rospective controlled studies, available to the treating physician for choo
sing the delivery route of choice and for minimizing morbidity and mortalit
y of both infant and mother. (C) 1998 Lippincott Williams & Wilkins.
