Emergency CT of the aorta showed filling defects in the distal aorta and iliac arteries, and

also in the right profunda femoris artery. The distal aortic wall had some calcification, but

Acute Lower Limb Ischemia no dissection flaps. All the other arteries were relatively healthy. CT angio should not be
used routinely for patients with acute ischemia, but only when a clinical diagnosis was
uncertain.

An elderly patient presented with a few hours of acute bilateral lower limb
ischaemia with pain, pallor, paresthesia, and coldness. He denied any history of
palpitations or angina, backpain or abdominal discomfort, or previous claudication,

but was hypertensive. His femoral pulses were not palpable, and his feet were cold
and pale.
