1 Endovascular treatment of renal artery aneurysms and renal arteriovenous fistulas 
Zhongming Zhang, MD, Min Yang, MD, Li Song, MD, Xiaoqiang Tong, MD, Yinghua Zou, MD  Journal of Vascular Surgery  Volume 57, Issue 3, Pages (March 2013) DOI: /j.jvs Copyright © 2013 Society for Vascular Surgery Terms and Conditions

2 Fig 1 A young man (patient no. 12), who previously had abdominal penetrating trauma, presented with hypertension. A, Volume-rendering computed tomographic (CT) image showing giant right renal arteriovenous fistula (RAVF) with a dilated feeding artery (arrow) and early filling of the renal vein (arrowhead). B, Selective arteriogram of outflow vessel of the aneurysm with balloon occlusion via the microcatheter showing the aneurysmal fistula and early filling of the inferior vena cava (IVC). C, Arteriogram after coil embolization of the outflow vessel with balloon occlusion showing the aneurysmal fistula without filling of the IVC. D, Embolization of the feeding artery performed under the protection of an inflated balloon. There is persistent contrast medium in the aneurysm secondary to lack of blood flow. E, Final arteriogram demonstrating absence of RAVF filling with other branches preserved and improved nephrogram. A partial renal infarct is noted. F, Follow-up CT angiographic image 12 months after the procedure demonstrating no reperfusion of the RAVF, and the other branches are patent.

3 Fig 2 A 38-year-old woman (patient no. 11) presented with left flank discomfort, and a wide-necked renal artery aneurysm (RAA) was found. A, Left renal arteriogram demonstrating a saccular aneurysm located in the left segmental branch with the wide neck (arrow). B, Final arteriogram demonstrating the aneurysm was excluded from the circulation without evidence of an endoleak after placement of the stent graft (arrow).
