Cardiology MCQs Modified Blalock-Taussig shunt is: End to side anastomosis of subclavian artery to a pulmonary artery Side to side anastomosis of main pulmonary artery to aorta Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit Anastomosis of superior vena cava to right pulmonary artery Correct answer: 3. Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit In classic Blalock-Taussig shunt, the subclavian artery is divided and anastomosed to the pulmonary artery as an end to side anastomosis.
