[Drug-eluting stents restenosis 2 months after the procedure and necessitating semi-emergency off-pump coronary artery bypass].
Drug-eluting stents (sirolimus-eluting stent: Cypher stent) have showed a reducing the frequency of in-stent restenosis and a good safety profile. One case involving edge dissection with Cypher stent restenosis for 2 lesions was diagnosed in 2 months after the procedure. This case occurred in a hypertensive 63-year-old woman with complex coronary lesions. The coronary angiography showed uncovered proximal dissection with 90% restenosis in left anterior descending coronary artery to left main trunk and 75% restenosis in right coronary artery. We were able to perform semi-emergency off-pump coronary artery bypass (OPCAB). There is the relationship between coronary dissection and restenosis. Cypher stent delayed dissected arterial healing and promote some inflammation at the lesion. Patients implanted Cypher stent with uncovered coronary dissection need more frequent follow-up.
