title: [Aortocoronary bypass graft in coronary arterial stenosis with aortitis syndrome].
abstract: A 50-year old female who had aortitis syndrome with unstable angina due to severe coronary arterial narrowings is described. On the preoperative coronary arteriogram, 95% occlusion of the left anterior descending coronary artery (segment 6) and the left circumflex artery (segment 11), so-called "skip lesion" of aortitis syndrome, were revealed. The distal circumflex artery was well visualized through collateral vessels of the posterior descending branch of the right coronary artery. Therefore single aortocoronary bypass graft to the left anterior descending branch was done with good success. Postoperatively the patient has been completely free from anginal chest pain. Narrowing of the coronary artery due to aortitis syndrome is considered uncommon. Stenotic lesions have been reported to be limited mostly to the ostia and proximal segments of the coronary arteries, connecting to the aortic wall. Moreover, so-called "skip lesion" of the coronary artery as seen in this case is thought to be very rare.
