twin-to-twin transfusion syndrome

(redirected from Twin twin transfusion syndrome)
Intrauterine growth retardation in 1 twin due to an artery-to-artery vascular shunting, which may occur in a diamnionic-dichorionic placenta, accompanied by hydramnios; the ‘donor’ twin is anaemic, pale, lighter, smaller with organ hypoplasia; the recipient twin is plethoric, polycythemic, macrosomic, has increased vascular resistance and may develop heart failure

Fetal transfusion syndrome, fetofetal transfusion syndrome, stuck twin syndrome Obstetrics Intrauterine growth retardation in 1 twin due to an artery-to-artery vascular shunting, which may occur in a diamnionic-dichorionic placenta and be accompanied by hydramnios; the 'donor' twin is anemic, pale, lighter, smaller with organ hypoplasia; the recipient twin is plethoric, polycythemic, macrosomic, has ↑ vascular resistance and may develop heart failure.
