A novel concept in endovascular stenting for the treatment of old severely degenerated saphenous vein graft in the urgent setting.

We report a critically ill-patient admitted for NSTEMI with acute pulmonary congestion, showing at urgent cardiac catheterization a severely diseased saphenous vein graft as the culprit vessel, with huge atherothrombotic burden. The graft was successfully revascularized by the implantation of 4 M-Guard stent (for proximal to distal) creating a full metal jacket. The M-Guard technology consists on a stainless steel platform wrapped by a micron-level polymer net, that seamlessly expands when the stent is deployed, providing protection from embolic showers.
