Figure-eight kinking of the aorta (pseudocoarctation) coexistent with coarctation.

An asymptomatic young man presented with a cardiac murmur and hypertension only in the right arm. Angiograms showed kinking of the aortic arch with a figure-eight appearance consistent with pseudocoarctation. Before the kinked segment, also demonstrated were a stenotic lesion in the aortic arch proximal to the left carotid artery and profound collateral circulations in the right thorax. These findings strongly suggested a rare combination of pseudocoarctation and true coarctation. His hypertension was corrected following surgery with a bypass graft between the ascending aorta and the abdominal aorta.
