Discrete abdominal aortic stenosis presenting with bilateral lower limb claudication - A case report

Localized discrete abdominal aortic stenosis leading to bilateral lower limbs claudication is uncommon in Asians, especially among women. We report on the case of a 63-year-old woman with localized discrete abdominal aortic stenosis manifested as claudication in her bilateral lower extremities. A magnetic resonance angiography showed a short and asymmetric abdominal aortic stenosis at the third to fourth lumbar level below bilateral renal arteries. She received successful graft interposition and her clinical condition dramatically improved. A surgical specimen from the pathological examination revealed typical atheroscelrotic plaque resulting in an asymmetric narrowing of the lumen of aorta. The final diagnosis was discrete abdominal aortic stenosis, not coarctation of the abdominal aorta. Based on the findings of this case, we therefore suggest that the diagnosis of abdominal aortic stenosis should be considered when patients present with intermittent claudication and also that surgical intervention is the treatment of choice.
