Role of computed tomography in nonobstructive coarctation.

Two cases of nonobstructive or pseudocoarctation of aorta evaluated by computed tomography are presented. Clinical features along with chest radiography and computed tomography findings provided specific information, making further workup by catheterization and angiography unnecessary. As most cases of nonobstructive coarctation are asymptomatic and require no treatment, its recognition is of great practical importance.
