Cardiac and vascular intervention in thrombocytopenic congenitally cyanotic patients is more dangerous. Thrombocytopenia in these patients is related to immune thrombocytopenia, polycythemia, hyperviscosity, pseudothrombocytopenia, and drugs. Herein we report on a thrombocytopenic 8-year-old girl with tricuspid valve atresia and pulmonary valve stenosis admitted for catheterization. Thrombocytopenia (21,000/mm(3)) and shunt occlusion was noticed. Thrombocytopenia did not recover after intravenous immunoglobulin (IVIG) and phlebotomy therapies. During preparation for surgery, she suffered cardiopulmonary arrest. A Gore-tex graft was placed in the right pulmonary artery and truncus brachiocephalicus. After surgery, her platelet count spontaneously increased to within the normal range (178,000/mm(3) to 250,000/mm(3)). After resuscitation, she had right-sided hemiplegia sequelae, though there were no hemorrhagic findings on cranial magnetic resonance imaging (MRI) or computed tomography (CT) scans. Two months after surgery, the Blalock-Taussig (BT) shunt blood flow decreased, thrombocyte count dropped, and peripheral cyanosis reappeared. A Fontan operation was performed without hemorrhagic events, and after surgery the thrombocyte count reached 330,000/mm(3). We suggest that if a patient with cyanotic heart disease has thrombocytopenia and there is no apparent cause, hypoxia-related thrombocytopenia must be considered. After reoxygenation by shunt or corrective surgeries, thrombocyte count and functions will recover. (Ann Thorac Cardiovasc Surg 2008; 14: 329-332)
