Hypereosinophilic syndrome accompanied by Buerger's disease-like femoral arterial occlusions.

A case of hypereosinophilic syndrome (HES) with a rare complication of Buerger's disease-like large arterial occlusion (AO) was successfully treated with emergent percutaneous transluminal angioplasty and anticoagulants plus corticosteroid. By reviewing 15 reported cases of HES with AO including the present case, we found man predominance but no other consistent characteristics in HES with AO, such as age, smoking history, eosinophil counts or previous treatments, thus, predicting AO in HES patients appears to be difficult. Vessel intervention should be considered as a treatment option, since treatment delay in some patients has resulted in the amputation of extremities.
