“…2 Although stent thrombosis is known to occur, 1,3,5,6 including late stent thrombosis, and thrombosis during the perioperative period, 7 intraoperative events related to coronary stents are rarely described. 8 However, late in-stent thrombosis is being described more frequently as more DESs are placed and is an important issue in the perioperative period when antiplatelet therapy is often held. The etiology of late stent thrombosis includes incomplete endothelialization of the stent, stenting across ostia, plaque disruption in nonstented segments close to the stent margin, in-stent restenosis, and extensive plaque prolapse in the stented region.…”
