Spontaneous infrarenal abdominal aortic dissection (SIAAD) is a rare entity with various clinical presentations. We recently encountered the even rarer condition of a female patient suffering from chronic SIAAD with multiple intimal flaps and prominent lumbar artery collaterals; this all caused stenotic changes of the infrarenal abdominal aorta and produced progressive lower extremity pain and claudication in both her legs. This patient's condition was successfully managed by primary stent placement followed by balloon angioplasty.
