Abstract
A case of atresia of the left subclavian artery, right-sided aorta and tetralogy of Fallot is described. There was angiographic evidence of “subclavian steal” blood flow pattern, but other collaterals seemed more important. Accordingly, there were no symptoms of basilar artery insufficiency. The clinical diagnosis depends on the pulse and blood pressure recordings in both upper extremities. In cyanotic patients, a correct diagnosis might have important therapeutic consequences, as a Blalock-Taussig shunt operation cannot be performed on the side with the atretic subclavian artery.
