Arteriogram: Left Renal Artery Stenosis

Multiple Choice

Arteriogram: Left Renal Artery Stenosis
Procedure in detail: The procedure, indications, possible complications of an abdominal aortogram, and possible renal arteriogram were discussed with the patient. The patient agreed to have the procedure done and signed the consent.
Under sterile technique with fluoroscopy control, a vascular sheath was introduced in the right common femoral artery using the Seldinger technique. Through this sheath, a 5-French pigtail catheter was introduced and placed at the proximal abdominal aorta. Flush aortogram followed, and a digital subtraction study of the abdominal aorta, by placing the catheter close to the renal artery origin, was performed.
Evidence of mild atheromatous plaque disease involving the infrarenal abdominal aorta, causing focal dilation, is seen. No significant stenosis is noted at the aortic bifurcation.
The celiac axis, including the splenic artery, gastroduodenal artery, and hepatic artery, is normal.
On the right side, the renal artery is normal in caliber, without any significant stenosis. Segmental arteries are normal. Contrast nephrogram is also uniform.
On the left side, there is segmental narrowing at the origin of the left renal artery. The narrowed segment is approximately 2 cm in length, with the narrowing more than 50% to 60% seen. No significant distal stenotic dilation of the renal artery is seen. Segmental arteries of the left renal artery are normal. Nephrogram of the left kidney is also normal.
Since the digital subtraction study was done with stenosis analysis, left renal artery stenosis is in the range of 50% to 65%. Hence, a selective renal arteriogram was not performed.
Impression: A 2-cm stenotic segment involving the origin of the left renal artery with stenosis in the range of 50% to 65% is noted. Segmental arteries of the left kidney are normal. Nephrogram of the left kidney is also normal.
