In North America and Europe, over 27 million people suffer from peripheral arterial disease (PAD). Neglected PAD is a leading cause of disability among people aged 50 years and older. The resulting complications are a tremendous cost to society. PAD may produce symptoms from claudication to ulceration, gangrene and limb loss. The severity of presentation depends on the extent of the disease, the degree of stenosis (from minor stenosis to total occlusions) and the presence of collateral circulation. Overall, chronic total occlusions (CTOs) are more the rule than the exception in PAD. Traditionally, CTOs have been treated surgically, while percutaneous approaches were limited to the treatment of focal occlusions. We present the cases of 4 patients who were successfully treated with the Wildcat device. All of them were difficult cases, with one common denominator: the patients were not good surgical candidates or their surgery had failed. This was the case for 1 patient for whom surgery had to be performed twice. Percutaneous intervention with the Wildcat device can be an excellent alternative strategy for the most difficult CTOs. Further studies and challenging cases are needed to compare the Wildcat with other modalities, including surgery.
