Neonatal arterial occlusion with ischemic limb gangrene.

Arterial occlusion in the extremity of a neonate is a rare event of obscure etiology. The diagnosis implies an urgent situation which may result in extremity gangrene and ultimate loss of limb. In contrast, early diagnosis and appropriate management should result in preservation of a normal limb. The key to successful management appears to be an awareness of this common clinical condition in an uncommon clinical setting.
