Abstract:
The Norwood procedure with a modified Blalock-Taussig shunt (MBTS) is the first of the three-stage surgical palliation for infants with hypoplastic left heart syndrome. We report a patient with schistocytic hemolytic anemia that developed following a right MBTS with a Gore-Tex graft. Hemolysis associated with a MBTS has not been previously reported in the literature. Multiple packed red blood cell transfusions were required due to desaturation and hypoxemia. Hemi-Fontan procedure was performed early for chronic anemia. Hemolysis resolved post operatively even though the patient subsequently required a Gore-Tex central shunt for persistent cyanosis.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
