OC47 MYOCARDIAL REVASCULARIZATION TECHNIQUE IN TAKAYASU'S ARTERITIS

Abstract

Abstract Background: Takayasu arteritis is a vasculitis of the aorta and its major branches. The involvement of coronary arteries is not a rare occurrence. An optimal revascularization strategy for this disease has not been established. A diffusely diseased coronary artery has been a therapeutic challenge for cardiologists and surgeons. Long reconstruction is one of the Coronary Artery Bypass Grafting methods for treating diffusely diseased coronary arteries. Methods: We report the case of a 65-year-old patient with a claudicatio at 150–200 mt but also angina pectoris. A diffuse and critical disease of anterior descending coronary artery was found in the angiographic study. The surgical procedure was performed by reconstructing anterior descending artery with a saphenous vein patch associated with coronary aortic bypass in the left internal mammary artery. Results: The follow-up at 15 months showed excellent patency of coronary reconstruction with venous patch, a recovery of good ventricular function with the asymptomatic patient. Conclusions: The reconstruction of diffusely diseased coronary arteries with a patch of saphenous vein or mammary artery is a good technique, it is possible to guarantee a simultaneous revascularization of septal, diagonal and small lateral branches offering a wide coronary and myocardial reperfusion.The greatest advantage of this method is that the myocardium supplied by the side branches of the diffusely diseased coronary artery can be revascularized simultaneously. Patch reconstruction can be performed with good early and midterm results.
