Abstract

A 60-year-old lean man with claudication due to severe stenosis of the right common iliac artery (CIA) underwent balloon-expandable stent deployment. Nineteen months later, claudication and lower limb ischemia in the patient recurred after minor external pressure and computed tomography indicated collapse of the right CIA stent. We performed balloon angioplasty again and self-expandable stent deployment was performed, and the patient's symptoms were relieved. We suggest that the CIA in a lean person could be susceptible to external pressure.

Figure

  • Fig. 1 Collapse of the BES in the CIA due to minor external compression in a lean patient. A. Initial pelvic angiogram shows focal severe stenosis in the right CIA (left) and reconstruction of the right CIA after BES (right). B-D. CT angiography obtained 19 months after stenting shows that the stent in the right CIA is normally deployed on the anteroposterior view (B). Axial CT image shows a collapsed stent in the proximal portion of the right CIA (arrow) (C). Stent struts are sparse inside the black lines compared with the other areas and indicate stent compression (arrow) in the lateral plane (D). E. Follow-up CT image, obtained 1 additional year later, shows thrombotic occlusion of the collapsed BES (arrow). F. Follow-up pelvic angiogram shows a total occlusion of the stent (left) and a recanalized right CIA after SES implantation (right). BES = balloon-expandable stents, CIA = common iliac artery, SES = self-expandable stent
