Heparin-Bonded Viabahn and Drug-Eluting Bare Metal Zilver (PTX) Sandwich Stents in Femoral Chronic Total Occlusion: A Retrospective Review of Mid-Term and Long-Term Outcomes

Table 2

Further details on stents, access/closure device, and anticoagulation consumed or administered during the interventional procedure. Typical sandwich technique is defined by proximal and distal PTX stents with Viabahn in between.
