An 82-year-old man suffering from lower back pain and dyspnea presented to our institute in a state of shock. Computed tomography showed subtotal occlusion of the descending aorta with massive atherosclerotic calcification. As the proximal portion of the superior mesenteric artery was obstructed, emergency bypass from the right axillary artery to the bilateral external iliac arteries was performed, but the patient died 2 days later. Autopsy revealed that reddish-brown and verrucous masses obstructed the descending aorta, and high-grade thickening of the intima and extensive deposits of calcium in the lumina and medial layer were detected in the descending aorta histologically.
一名82岁男性因下背部疼痛和呼吸困难，在休克状态下被送至我院。计算机断层扫描显示降主动脉次全闭塞，并伴有大量动脉粥样硬化钙化。由于肠系膜上动脉近端受阻，遂进行了从右腋动脉到双侧髂外动脉的急诊搭桥手术，但患者于2天后死亡。尸检发现，降主动脉被红棕色疣状肿物阻塞，组织学检查显示降主动脉内膜高度增厚，管腔和中层有大量钙沉积。
