[Atheroembolic syndrome due to isolated infrarenal abdominal aorta stenosis and endovascular treatment: case report and review of literature].

One of the most common source of lower extremity atheroembolization is the aorta and particularly the infrarenal segment. Complex atherosclerotic plaque can lead the patient to gangrene and major amputation. When the origin of embolization is a focal lesion, endoluminal methods could be an alternative to surgical treatment. Although the experience with aortic stent is limited, the results obtained so far seem to be encouraging. The case of a mid-age heavy smoker woman with a history of the abrupt onset of painfull cyanotic toes in the left foot and subsequent complete gangrene of the first digit in the same foot is herein reported. Angiography and CT scan revealed an high-grade calcified aortic infrarenal plaque. Because of the discrete characteristic of the lesion, an endovascular approach with a Palmaz stent was elected. The stenosis was successfully treated: the patient experienced the complete resolution of the toe painfull cyanosis within 3 months, the stent remained patent through a 24 months follow-up and no subsequent embolic episodes were observed.
