The histological characteristics and virtual histology findings of the tissues obtained by a distal protection device during endovascular therapy for peripheral artery disease

Distal protection during EVT would be considered when the lesion is located in the iliac artery, is an ulcerative lesion, and when VH-IVUS determines that the lesion contains NC. The plaque in PAD patients mainly corresponds to the stable phenotype; however, it may also exhibit the characteristics of the vulnerable phenotype.
