	Introduction

Top Introduction

 
The accompanying figures illustrate a case of a vascular ring formed by the right aortic arch, aberrant left subclavian artery, and left ductus ligamentum.

A, Frontal projection: A large right-sided filling defect is seen on the barium esophagogram (E) performed during cardiac catheterization (arrow). The positions of the transvenous catheter tip in the main pulmonary artery (P) and of the retrograde catheter in the ascending aorta (A) are shown. B, Lateral projection: A large posterior filling defect is seen on the barium esophagogram (arrow).

View larger version (115K): [in this window] [in a new window]   Figure 3. A, Frontal ascending aortogram demonstrates the right aortic arch, which is not related to the filling defect. B, Lateral view of the arch and descending aorta clearly demonstrates the spatial relation between the aorta and the filling defect. AO indicates aorta; E, barium esophagogram.

View larger version (99K): [in this window] [in a new window]   Figure 4. A, Frontal view of the aortogram shows that the filling defect is caused by the Kommerell's diverticulum (KD), from the tip of which the aberrant left subclavian artery originates. AO indicates aorta; E, barium esophagogram.
