[Implantation of endoprostheses in aortocoronary bypass. Preliminary experience at the Thoraxcenter of Rotterdam].
An intraluminal stent was implanted in 5 patients after dilatation of an aorto-coronary venous graft. In the first 4 patients the procedure was motivated by restenosis after angioplasty. In the 5th patient the stent was implanted as a first-line measure in a case of dilated venous bypass stenosis. Stent implantation carries a risk of thrombosis and requires effective anticoagulation. Thus, one of our patients had to be reoperated upon for prosthetic thrombosis facilitated by the withdrawal of anticoagulants owing to a gastrointestinal haemorrhage. After a 3-month follow-up, the results seem to be encouraging in spite of a case of restenosis located at the proximal end of the tutor. However, more time will be needed to determine precisely the effectiveness of stents in the prevention of restenosis after venous graft dilatation.
