[A case of coronary artery bypass grafting using patch mounted graft technique for aortitis syndrome with left coronary ostial stenosis].

ABSTRACT

Coronary artery bypass grafting (CABG) was performed on a 36-year-old female for treatment of aortitis syndrome with left coronary ostial stenosis. The left anterior descending artery was anastomosed with the left internal thoracic artery. The circumflex artery was anastomosed with the saphenous vein. In the proximal anastomosis, the ascending aorta was sutured with a gelatin sealed knitted Dacron graft patch and anastomosed with the saphenous vein to prevent late occlusion due to intimal proliferation. Graft angiography 40 days and one year after the operation showed good patency of both grafts. Patch mounted graft technique seemed to be suitable for CABG in aortitis patients with the high incidence of late occlusion.
