경피적 Stent 삽입술로 치료한 하지 허혈과 급성신부전이 합병된 대동맥 박리증

Abstract

A 62-year-old woman was admitted due to acute pain in the back and the right lower extremity. CT and angiography showed a chronic dissection of the ascending aorta and a newly developed dissection of the descending aorta complicated with ischemia of the left renal artery and right lower extremity. Therefore, a Wall stent was inserted percutaneously at the descending thoracic aorta and the stenotic left renal artery was opened by percutaneous transluminal renal angioplasty with a Mac (4.0×22 mm, Amg, Korea) stent. Thereafter, renal function was normalized and the blood pressure was better controlled at discharge. A follow up CT scan 3 months after the procedure showed patent true lumen of the descending thoracic aorta and left renal artery.
