Intrauterine vascular deficiency of the upper limb.

We report six cases of intrauterine vascular deficiency of the upper limb, presenting over a 12-year period, with established areas of necrosis at the time of birth. Three of the six mothers were diabetic. An urgent examination of the neonate should be done to exclude occult systemic thomboses, as early anticoagulation or thrombolytic therapy may be indicated. The majority of cases were managed conservatively with dressings and splintage of the limb; exceptionally surgical intervention was required. Long-term sequelae included flexion contractures and shortening of the forearm bones.
