Overview
The Blalock-Taussig shunt is a surgical procedure that are done as palliative procedures for cyanotic heart defects which are common causes of blue baby syndrome. In modern surgery, this procedure is temporarily used to direct blood flow to the lungs and relieve cyanosis while the infant is waiting for corrective surgery. One branch of the subclavian artery (Arteria subclavia) or carotid artery (Arteria carotis) is separated and connected with the pulmonary artery (Arteria pulmonalis). The lung receives more blood with low oxygenation from the body. The first area of application was tetralogy of Fallot. This procedure has been modified into modified Blalock-Taussing Shunt (mBTS). In this modified procedure a graft from innominate artery or subclavian artery is placed to the corresponding pulmonary artery.
Historical Prospective
The original procedure was named for Alfred Blalock, surgeon, Baltimore, (1899–1964) and Helen B. Taussig, cardiologist, Baltimore/Boston, (1898–1986) who, along with Blalock's African American laboratory technician Vivien Thomas (1910–1985), developed the procedure. Taussig, who treated hundreds of infants and children with this disorder, had observed that children with a cyanotic heart defect and a patent ductus arteriosus (PDA) lived longer than those without the PDA. It therefore seemed to her that a shunt which mimicked the function of a PDA might relieve the tetralogy patients' poor oxygenation. In 1943, having broached the possibility of a surgical solution to Dr. Robert Gross of Boston without success, Dr. Taussig approached Blalock and Thomas in their Hopkins laboratory in 1943.

Modified Blalock-Taussig Shunt
A modified method of inserting a shunt was developed in 1962 by Klinner using teflon as prosthetic graft material between the subclavian artery and the pulmonary artery is used to prevent scarring of the subclavian arter.
