Focal stent collapse in a patient with systemic schlerosis

We report a patient with systemic sclerosis having implantation of a 35 mm beStent with immediate success but developing engine at follow-up. A focal stent collapse with focal hyperplasia in and outside the stent was documented by ultrasound after 2 mos. A 14mm Palmaz-Schatz stent was successfully deployed into the collapsed beStent, with good 6-mo angiographic result. The stent collapse was probably due to unequal distribution of radial forces and possibly reactive hyperplasia in this unique patient with systemic sclerosis.
