Objective:
To discuss a rare variation of abdominal aorta breaking in two.
Methods:
An in-patients, female, aged 76, admitted for asthenia of right extremities, underwent gadolinium-enhanced magnetic resonance angiography (MRA) of cerebral and abdominal vessels and abdominal MRI in whom the conventional angiography had failed to reveal this vascular abnormality.
Results:
MRA showed a clearly separated abdominal aorta. The upper part of the abdominal aorta terminated under the two renal artery branches and the lower part terminated at the level of L(3 - 4). The compensated enlarged superior and inferior mesenteric artery connected these two isolated parts of abdominal aorta.
Conclusion:
This rare variation of abdominal aorta without any symptom is probably caused by some external force during the embryonic period.
