Late Thrombosis of Sirolimus-Eluting Stent: A Multifactorial Problem
Successive IVUS images of the LAD artery from proximal (a) to distal part (d) of the fractured stent are shown after the occlusive thrombus was mechanically removed. (a) Complete, transverse fracture is seen with a spiral distortion of stent struts (parallel arrows). (b) Stent gap with totally missing struts. (c) Re-appearance of a few struts (orthogonal arrows). (d) Intact distal part of the stent.
