Abnormally high failure rate for femoral angioplasty in patients with pseudoxanthoma elasticum

Abstract

Pseudoxanthoma elasticum (PXE) is an inherited disease characterized by skin lesions, central blindness, and progressive peripheral occlusive disease. Severe claudication is a frequent symptom for which angioplasty represents a possible therapeutic avenue. We report the outcomes of four patients with PXE treated by angioplasty and stenting of the superficial femoral artery in two centers. These patients exhibited an abnormal failure rate for angioplasty and stenting of the superficial femoral artery, suggesting an as yet unknown susceptibility in such patients. In the absence of further evidence, we do not recommend arterial angioplasty with stenting as a primary surgical approach in PXE patients with femoral artery lesions.
