[Late structural discontinuity and migration of a bioabsorbable scaffold in a saphenous vein graft]

The use of bioresorbable vascular scaffolds (BVS) has many important and potentially useful features, on both pathophysiological and clinical grounds, for the treatment of native coronary artery stenosis. These advantages are less well established when BVS are employed in saphenous vein graft disease. We here describe a peculiar behavior of a previously (6 months) implanted BVS in a degenerated saphenous vein graft during treatment of an in-stent restenosis in a patient suffering from unstable angina. This BVS particular performance seems to suggest that different pathophysiological and anatomical conditions may play a relevant role in affecting the results of transluminal vascular therapy.
