A 77-year-old woman underwent endovascular abdominal aortic repair (EVAR) for an abdominal aortic aneurysm (AAA).Five years after surgery, she visited the hospital with the chief complaint of a fever. Enhanced computed tomography (CT) showed enlargement of the AAA around the stent-graft and a mass, which was suspected to be an abscess, outside the aneurysm. A blood test revealed a high level of inflammatory response. The patient was diagnosed with infectious AAA. She received antibiotics; however, the inflammatory response did not completely improve. A second CT scan revealed that the suspected abscess had a spreading tendency. The patient was referred to our hospital for a highly suspected stent-graft infection. We performed Y-graft replacement using a rifampicin-immersed graft, and as much as possible of the wall around the aortic aneurysm was removed. The inflammatory response improved rapidly after the operation, and the patient was discharged 15 days later. According to the results of a pathological examination, a diagnosis of xanthogranulomatous inflammation and fibrosis was made. Here, we report a rare case of xanthogranulomatous inflammation of the aortic aneurysm wall after EVAR.

A 40-year old man with chest pain was admitted to our hospital. A three-dimensional CT revealed an unruptured left coronary sinus of Valsalva aneurysm and mild stenosis of the left main trunk. An echocardiogram revealed severe aortic regurgitation. He was operated on with an aortic root replacement procedure. Though the procedure was itself uneventful, he could not be weaned from cardiopulmonary bypass because of unexpected coronary events ; relative stenosis of the RCA and stretched LMT due to a huge aneurysm of the sinus of Valsalva. Additional CABG with LITA to LAD and SVG to RCA led to weaning from cardiopulmonary bypass. Left coronary sinus of Valsalva aneurysm is rare, and it requires early surgical intervention for an increase in the diameter of the aneurysm together with myocardial ischemia due to compression of the coronary artery.
