[Left coronary ostial stenosis in aortitis syndrome--patch mounted graft technique for proximal anastomosis].

Late restenosis or total occlusion of proximal aortic anastomosis frequently occurs due to intimal proliferation in aortitis CABG patients although successful early postoperatively. A Gore-Tex patch (diameter 20 mm) mounted grafts to LAD and CX with a single ostium was sutured in the inflammatory aorta to prevent late occlusion in a 40-year-old female patient. Postoperative CAG a month after showed a patent graft to LAD and improved exercise treadmill test. Graft to Cx occluded due to competed flow from LAD. No aneurysm was found in the proximal anastomosis. Tissue nonpermeable Gore-Tex mounted graft is considered to be suitable for CABG in aortitis patients with the high incidence of late occlusion.
