Twin embolization syndrome
Updates to Article Attributes
The twinTwin embolisation syndrome (TES) is a rare complication of a monozygotic twin pregnancy following an in utero demise of the co-twin.
Pathology
It was traditionally thought to result from the passage of thromboplastic material into the circulation of the surviving twin which causes ischemicischaemic structural defects in various organs (particularly the highly vascularised organs such as the central nervous system, gastrointestinal tract, and genitourinary system). An acute haemodynamic shift from live to dead fetus resulting in hypoperfusion is more recently thought to play a role 3.
Associations
There is usually an underlying twin-twin transfusion syndrome as a causative association.
Radiographic features
Antenatal ultrasound
The presence of a dead twin associated with a surviving twin with various anomalies may suggest the diagnosis. Such anomalies include :
CNS anomalies
Non-CNS anomalies
Treatment and prognosis
While it carries a poor outcome, prenatal sonographic diagnosis may influence the antenatal neonatal management of the surviving monozygous twin 1.
