[Vascular Behçet disease presenting large right coronary artery pseudoaneurysm after percutaneous coronary intervention( PCI): report of a case].

A 37-year-old man was diagnosed with angina pectoris and underwent percutaneous coronary intervention(PCI) procedure for right coronary artery in other hospital. Five months after PCI procedure, he was admitted to the hospital because of fever, chest pain and respiratory discomfort. He was diagnosed as having a large right coronary artery pseudoaneurysm which was about 40 mm in diameter. He was transfered to our hospital. We did coronary artery bypass grafting(CABG)[ saphenous vein graft (SVG)-#3] and pseudoaneurysm closure, and he left our hospital on 37 post-operative day. After discharge from our hospital, he developed iliocecal ulcer, oral aphtha, folliculitis and arthralgia and was diagnosed with Behçet disease. Seven months after the 1st surgery, proximal anastomosis site of SVG was ruptured and presented huge ascending aorta pseudoaneurysm. We performed autologous pericardial patch plasty on ascending aorta, and covered there with omentum flap. He uneventfully left our hospital on 19 post-operative day.
