ABSTRACT
We report a case of stent graft occlusion, severe lower extremity ischemia, and ruptured abdominal aortic aneurysm due to type B acute aortic dissection 3 years after endovascular aneurysm repair. He admitted our hospital because of abrupt back pain and dysesthesia of bilateral lower limb. Contrast-enhanced computed tomography (CT) scan showed type B acute aortic dissection and occlusion of the stent graft due to dynamic compression by the false lumen. Emergent right axillo-bifemoral bypass operation was done for his critical limb ischemia. Immediately after the successful operation, he fell into shock vital and dissecting abdominal aortic aneurysm rupture was revealed by CT scan. We performed the stump occlusion of the infrarenal abdominal aorta and the bilateral common iliac arteries by abdominal midline incision. Postoperative myonephropathicmetabolic syndrome due to the left ischemia resulted in amputation of his left lower leg for lifesaving. While EVAR cases are increasing, various its complications come to be reported. We consider that this case report might be cautious about the indication of EVAR for the younger generation.

ABSTRACT
An 80-year-old woman was incidentally found to have a cardiac tumor on the aortic valve by echocardiography. Papillary fibroelastoma(PFE) was strongly suspected, and urgent operation was performed to prevent embolism. Two tumors were identified arising from the left and right cusps with wide stalks, and aortic valve replacement was performed. By pathological examination, the tumors were diagnosed as PFEs. A small tumor was also found on the non-coronary cusp, which was considered as possible PFE or Lambl's excrescence. In the case of multiple PFEs on one valve, valve replacement, instead of simple excision of tumors, should be considered.
