Figures 7A, B & C Small branches arising from the left
pulmonary artery are seen on the CT scan. The relationship
of the
azygos, aorta and esophagus isshown.
Figures 8A, B & CThe azygos arch is seen enter-ing
the superior vena cava.Note the small lymph nodes lying
within fat anterior to the trachea. This space is readily
accessible to the mediastino-scope.
Figures 9A, B & C The superior vena cava is lateral to the
aortic arch.
Figures 1OA, B & C Five vessels are seen cut in cross-
section.
