Aortitis is an inflammatory arteriopathy that often progresses to obliteration of multiple large arteries. Surgical treatment for obstructive lesions due to aortitis syndrome therefore is difficult in many cases. The patient was a 23-year-old female who at the age of 19 had been diagnosed as aortitis syndrome with cerebral vessel involvement, and she subsequently received steroids. She increasingly experienced syncopal attacks, and was indicated for surgical treatment. Angiography revealed obstruction of the left common carotid and left subclavian arteries, and severe stenosis of the right common carotid and right vertebral arteries. She underwent bilateral ascending aorta-carotid artery bypass operation with 7mm ring-supported EPTFE grafts. After the operation she developed clinical signs of temporary brain damage due to hyperperfusion syndrome, but she now completely recovered and maintains a good clinical condition.

The sudden onset of anuria in a 71-year-old man was found to be caused by the non-inflammatory (atherosclerotic) large abdominal aortic aneurysm compressing the bilateral ureters. A computed tomography scan demonstrated the bilateral extrinsic ureteral obstructions due to the large aneurysm of 13cm in diameter, left hydronephrosis and no thick layer of perianeurysmal fibrotic tissue. On the 9th day from the onset of anuria, an emergency operation was performed. There was no fibrotic adhesions around the aneurysm and mobilization of the aorta was easy. A straight Dacron prosthesis was inserted between the infrarenal aorta and the bifurcation of the abdominal aorta following resection of the aneurysm of the atherosclerotic origin. Soon after the operation, the patient had very good urinary output with adequate recovery of renal function. This case seems to be very uncommon, but very important in the surgical management of abdominal aortic aneurysm complicated by oliguria or anuria.

We present the case of 83-year-old male patient. He was under observation as an outpatient with mild to moderate aortic stenosis and regurgitation since 75 years old. He underwent surgery because of repeated hospitalization by heart failure due to progressive aortic valve stenosis and regurgitation, mitral valve stenosis and regurgitation, and tricuspid regurgitation. Elective aortic valve replacement, mitral valve replacement and tricuspid valve repair was performed. Even though his condition after surgery was stable, suddenly feature like low output syndrome appeared on day 6, and led to a mortality on day 8 after operation. Ejection fraction was kept above 50 percent before and after surgery, which indicated to Heart Failure with preserved Ejection Fraction (HFpEF). After autopsy examination, by immunohistochemical staining identified transthyretin, we demonstrated previously undiagnosed transthyretin-related cardiac amyloidosis (TTR-CA).
