Abstract
DILATATION of the blood vessel distal to a point of constriction has become a recognized phenomenon and apparently follows physical and hydrodynamic principles.1 , 2 The poststenotic dilatation that accompanies stenosis of the pulmonic and aortic valves and coarctation of the aorta seemingly also occurs when a cervical rib constricts the third part of the subclavian artery.Hitherto, the poststenotic dilatation of the subclavian artery associated with a cervical rib has been called an aneurysm. Such a designation implies local disease or injury of the arterial wall — a condition that seems unlikely in view of general agreement that removal of the . . .
