摘要

BACKGROUND: Patch angioplasty is one of the several surgical options for patients with left main coronary ostial stenosis. It restores native antegrade blood flow in the left main coronary artery (LMCA) and does not leave the patient with graft-dependent retrograde perfusion. Various direct techniques have been described for left coronary ostioplasty. Herein, we described the use of autologous aortic tissue in the surgical treatment of left main coronary ostioplasty, and reported the short- and long-term outcomes of the patients. METHODS: Between January 2003 and December 2010, 11 patients (nine males and two females) underwent surgical patch angioplasty for LMCA ostial stenosis using autologous aortic tissue as the patch material. RESULTS: All patients survived the operation, and there were no significant postoperative complications. The follow-up period was 44.09 +/- 30.26 months (range, 1-94 months), and no deaths or restenoses were observed during follow-up. CONCLUSIONS: The use of autologous aortic tissue as an onlay patch for reconstruction of left main coronary ostial stenosis is safe and free of major complications. This tissue is a reasonable material for treating selected types of LCMA patients.
