Congenital bowel perforation in twin-to-twin transfusion syndrome

Abstract

Two unrelated survivors of twin-to-twin transfusion syndrome (TTTS) presented with intestinal perforation at birth. Both were localised perforations without any suggestion of widespread ischaemic disease to the splanchnic bed. Histopathology from the perforation site showed evidence of focal ischaemic necrosis, presumably from a vascular accident. One infant later died of multiple organ failure with major brain damage, but the other survived without long-term sequelae. These two cases appear to represent an unreported variation of the ischaemic intestinal complications of TTTS.
