Another younger 48-year old man with
insulin dependent diabetes was admitted
with sudden onset of chest pain, hypoten-
sion, and acute left lower limb ischemia.
CXR did not show significant mediastinal
widening. Left lower limb pulses were
absent. This should point to a high suspi-
cision of acute aortic dissection.
Actue type A aortic dissection was con-
firmed on urgent CT scan. Note the
involvement of dissection flap in the
ascending aorta where the primary tear
originates, and also dissection of the
SMA.
Pressure of blood in the false lumen com-
presses and occludes flow into the left
common iliac artery.
