Test 3. Radiology - Renal Angiography

7. Renal Angiography

Purpose : 신동맥 협착(atherosclerosis, fibrodysplasia...)

aneurysm, vasculitis, thrombosis, renal mass 평가를 위해서

Stenosis shapes of renal artery fibromuscular dysplasia.

A. focal stenosis / B. beaded-multifocal stenosis / C. diffuse segmental stenosis.

Case 1.29-year-old woman with a focal stenosis in the midportion of the left renal artery.

Case 2. 26-year-old-man with a beaded stenosis in the midportion of the right renal artery.

Case 1.

A. Angiography shows a focal stenosis (arrow).
B. There is an approximate 40% residual stenosis (arrow)

after percutaneous transluminal renal artery angioplasty.
C. Six months later, CT angiography shows no interval change in the residual stenosis (arrow).
D. Twenty-six months later, CT angiography shows no interval change in the residual stenosis

(arrow).

Case 2.

A. Angiography shows a beaded stenosis of a renal artery (arrow).
B, C. Follow-up CT angiography and angiography show restenosis (arrows) of the renal artery

after 28 months. At that time, there was a sudden elevation of blood pressure.
D. After a second percutaneous transluminal renal artery angioplasty,

selective right renal angiography shows a successfully dilated renal artery.

Clinical cure was achieved

after performing a successful second percutaneous transluminal renal artery angioplasty.
