Background: In-stent stenosis remains the major disadvantage of coronary interventions. Extensive applications of the intracardiac devices especially involving long segments of coronary arteries have resulted in an increase in the number of cases of in-stent stenosis. That may require aggressive surgical approaches.

Methods: Between June 2006 and October 2007, 7 patients with long-segment left anterior descending artery in-stent stenosis were operated on in our institution. Two of the operations were off pump with minimally invasive techniques, whereas the latter 5 patients were operated on through cardiopulmonary bypass.

Results: All patients were male, except for the last patient; their ages were between 43 and 71 years (59.67 ± 12.36). They all had received an intracoronary stent for the left anterior descending artery (3 to 11 months before surgery). The first 2 operations were minimally invasive off-pump procedures; however, the latter 5 were with cardiopulmonary bypass. Mean follow-up was 6.33 ± 4.13 months, and a postoperative coronary angiogram was performed on all the patients.

Conclusions: Although long-segment in-stent stenosis complicates subsequent coronary artery bypass grafting operations, stent removal with coronary endarterectomy seems to be the technique of choice because it is effective and safe.
