Dilatation and Pulsation of the Left Subelavian Artery in the Roentgen-Ray Diagnosis of Coarctation
نویسنده
چکیده
Postero-anterior chest roentgenograms in 17 of 20 patients with coarctation of the aorta showed widening of the left upper mediastinal shadow attributed to dilatation of the left subclavian artery; pulsations of this vessel were evident in 12 of 13 cases with roentgenkymograms. In 3 of the latter cases rib notching was absent or equivocal. The subclavian pulsations may be observed fluoroscopically. Recognition of dilatation and pulsation of the left subclavian artery may provide roentgenologic corroboration of a diagnosis of coarctation of the aorta even in the absence of rib notching.
