We report a case of surgical treatment for idiopathic nonspecific inflammatory aneurysms of the abdominal aorta (AAA) with high-dose steroid therapy. The patient was a 35-year-old man who underwent steroid therapy (30 mg/day prednisolone) for idiopathic nonspecific inflammatory AAA and right common iliac artery aneurysm (CIAA) for 5 months. However, the sizes of the aneurysms were slowly increasing, and they were sacculated types, so surgical replacement was performed. Before the operation we continued to give 30 mg/day prednisolone, because decreasing the medicine made the c-reactive protein (CRP) value rise. Perioperatively the therapy continued, and the postoperative course was uneventful. With appropriate steroid therapy, replacement of idiopathic nonspecific inflammatory aneurysms of the abdominal aorta can be performed. It is also important to follow up the patient from long-term, to monitor for pseudoaneurysms from anastomosis or new aneurysms.

We report a case of surgical treatment for pseudoaneurysm 4 years after Patch-and-Glue Repair of left ventricle free wall rupture (LVFWR) due to acute myocardial infarction (AMI) in 2004 in a 74-year-old woman, she had been followed in our hospital. And 2 years later, echocardiography and MRI showed a pseudoaneurysm at the repair spot which was growing very slowly. Since we found a thrombus in the pseudoaneurysm, a redo operation was performed in 2008. The pseudoaneurysm was successfully extirpated, under cardiopulmonary bypass. The infracted area had degenerated to scar tissue and we could suture tightly without worrying about a fissure in the wall. We can use Patch-and-Glue Repair to rescue the LVFWR patients due to AMI in the acute stage because it is possible to remove the pseudoaneurysm in the future, on pseudoaneurysm excision in a firmly infarcted area is possible in the chronic stage.

Giant coronary artery aneurysms are relatively rare and are usually associated with Kawasaki disease, atherosclerosis, congenital disease, or trauma. Although a coronary-pulmonary artery fistula is a known complication, clear guidelines for treatment of this condition remain unavailable. We report a case of multiple giant coronary artery aneurysms associated with a coronary-pulmonary artery fistula in a patient who underwent fistulotomy, aneurysmectomy, and coronary artery bypass graft surgery. A 66-year-old woman was initially evaluated by her primary care physician following right breast cancer surgery. She denied any specific symptoms; however, she was referred to our hospital for evaluation of an abnormal shadow detected on chest radiography. Contrast-enhanced computed tomography (CT) performed at our hospital revealed multiple giant coronary artery aneurysms(approximately 45 mm in size), as well as right and left coronary-pulmonary artery fistulas. We performed simultaneous aneurysmectomy, fistula resection, and coronary artery bypass grafting for management of the giant coronary artery aneurysms concomitant with coronary-pulmonary artery fistulas. Threedimensional CT was useful for accurate imaging of the location of the coronary artery aneurysms, fistula vessels, and the left anterior descending, and left circumflex arteries. It is essential to accurately delineate the boundary between the aneurysms and healthy coronary arteries and fistula vessels, and coronary artery bypass graft surgery should be performed if necessary. We report a rare case of the aforementioned clinical condition, together with a literature review.
