Implantation of an endoluminal prosthesis at the distal anastomosis of a bypass graft for abrupt closure following balloon angioplasty. A coronary Wallstent was implanted in a 10-year-old saphenous vein bypass graft following a PTCA that was complicated by abrupt closure. Anterograde flow was restored and no myocardial necrosis resulted. One week later, bypass surgery was performed due to a bleeding complication associated with the anticoagulation regimen.
