Choreoathetotic syndromes are frequently observed in children after congenital cardiopathy surgery. To report the case of an adult patient who developed a choreoathetotic syndrome after cardiac operation, probably related to a transitory hypometabolism of basal ganglia. A 52-year-old patient underwent heart surgery under circulatory arrest and deep hypothermia, for type III dissecting thoracic aorta aneurysm. Two weeks later she developed an acute choreic syndrome. The positron emission tomography using fluorodeoxyglucose (FDGC-PET) showed a bilateral hypometabolism of basal ganglia. After haloperidol administration, choreic syndrome improved and 6 months later FDGC-PET was normal. Choreoathetosis has been described as a rare complication after heart surgery. The authors suggest that this movement disorder may be related to hypothermia that can induce a reversible basal ganglia metabolic damage. © 2009 Springer-Verlag.
