What Practical Factors Guide the Choice of Stent and Protection Device during Carotid Angioplasty?

Working principle of A) distal occlusion balloons (DOB); B) distal filters (DF); and C) proximal occlusion devices (POD).

Larger open-cell-designed stents insufficiently scaffold vulnerable lesions in tortuous anatomy.¹⁵

Stent selection for tortuous carotid lesions a) pre- and b) post-procedural angiography of CAS with open cell nitinol stent (Precise) preserving original anatomy and c) pre- and d) post-procedural angiography of CAS with closed cell Cobalt Chromium alloy stent (Carotid Wallstent) causing kinking of the artery distal of the lesion.
