Microvascular surgery to preserve a preterm infant's ischaemic arm.

Address for correspondence: Mr P M Davison, Bangour General Hospital, Broxburn, West Lothian Acute neonatal gangrene is an uncommon but devastating event. It may follow the adjustments in circulation that occur after birth, which may lead to an embolus arising from a thrombus within the ductus arteriosus or from an extension of an umbilical artery thrombosis. ' Arterial blood sampling2 and compression during delivery can both result in acute neonatal gangrene, and the condition also occurs in babies with sepsis, dehydration, and polycythaemia.
