Purpose. To report the effectiveness of left renal artery (LRA) occlusion using Amplatzer Vascular Plug (AVP) II as treatment for a high-flow renal arteriovenous fistula (RAVF) with multiple renal vein aneurysms (RVA) to prevent aneurysm rupture and cardiac decompensation. Case Report. A 59-year-old female suffering from a post-traumatic RAVF presented with tachycardia and increased cardiac output (CO). Doppler ultrasonography and computed tomography (CT) scan revealed a high-flow RAVF with multiple RVAs and unilateral critically reduced kidney function. Appreciating recent interventional therapeutic advances, the patient was treated with endovascular placement of AVP II into the left renal artery (LRA) resulting in complete occlusion of the RAVF to effectively reduce the risk of RVA rupture and cardiac decompensation. No anti-platelet medication was administrated after the occlusion of the LRA. The patient’s physical capacity improved since right heart volume strain was normalized, and CO was reduced. Conclusion. Transbrachial AVP II occlusion of the LRA is effective to occlude high-flow RAVFs to prevent risk of life-threatening RVA rupture. Additional follow-up is warranted to verify long-term effectiveness of this approach.

Background: Renal vein aneurysms (RVAs) are considered rare clinical entities. RVAs can be secondary to thrombosis, venous hypertension, or renal arteriovenous fistula (RAVF). RVAs secondary to RAVF are rare. Patients with RVA may present with hypertension, abdominal pain, hematuria, or may even be asymptomatic. However, there may be life-threatening emergencies including aneurysm rupture, thrombosis, and pulmonary embolism. The treatment of RVAs includes reconstruction of the renal vein, nephrectomy, and endovascular treatment. Purpose: In this technical note, we report the endovascular treatment of a giant RVA that developed secondary to an acquired RAVF by the placement of multiple vascular plugs. Conclusion: Endovascular occlusion of the RAVF with vascular plugs is effective to prevent a life-threatening rupture of RVA. Clinical follow-up is crucial to detect leakage or migration of the vascular plugs.

Abstract Background We report the use of a 4 mm vascular Amplatzer for the occlusion of a renal arterovenous fistula between the renal artery, at the hylum trifurcation point, and an aneurismatic vein draining into the main renal vein, where there was no possibility to use any other device from the venous side, because of the diameter and the high flow, neither from the arterious side without sacrificing lobar branches. The device was implanted at the exact point of communication, like a patent foramen ovale occluder, with the distal disc into the artery lumen and the other two proximal discs into the venous side. Case presentation A 34-years-old Caucasian woman suffered several episodes of paroxysmal supraventricular tachycardia associated with dyspnoea, after the onset of post-pregnancy hypertension. She underwent CTA, spectral Doppler sonography and angiography which showed a renal arteriovenous fistula (RAVF) between the renal artery, at the hylum trifurcation point, and an extremely ectatic vein draining into the main renal vein of the right kidney. With both arterial and venous access, the RAVF was selectively embolized using a 4 × 6 mm Amplatzer Vascular Plug II, released into the communication between artery and vein ensuring the patency of vessels involved. The RAVF was almost completely excluded and the hemodynamic effects associated were also corrected. Conclusions The use of this device, though in an alternative way, allowed the exclusion of the high flow A-V fistula without sacrificing any parent renal vessel and preserving the renal function.

Congenital renal artery aneurysm is uncommon. Moreover, renal artery aneurysm concomitant with a congenital renal arteriovenous fistula is extremely rare. Transarterial embolization is the first-line treatment for these conditions. We report a case of a patient with congenital renal artery aneurysm concomitant with a congenital renal arteriovenous fistula of the upper polar left renal artery which was successfully treated by transarterial embolization with coil, glue, and Amplatzer vascular plug.

Renal artery aneurysm (RAA) concomitant with a renal arteriovenous fistula (RAVF) has been infrequently reported in the literature. We report a case of a 42-year-old man suffering from a giant RAA combined with a congenital high-flow RAVF. The contrast-enhanced CTA showed a 12.7-cm RAA synchronous with an RAVF between the right renal artery and a draining vein. After a comprehensive preoperative assessment, an endovascular approach was decided. Successful embolization was performed using an Amplatzer vascular Plug, and multiple coils. Completion angiogram demonstrated no flow into the RAA. The results of longterm follow-up demonstrate that endovascular techniques are safe and effective for the management of RAAs combined with high-flow RAVF.

Objective: Anteriovenous fistula is a high-flow vascular malformation. Anteriovenous fistula is characterized by a direct connection between an artery and a vein without the presence of a nidus (network of arterial and venous channels). Renal artery aneurysm concomitant with a renal arteriovenous fistula is extremely rare. Case report: We reported the case of a 45-year-old female who has giant renal artery aneurysm combined with high-flow RAVF who presented with gross hematuria. The patient’s embolization of a giant extrarenal aneurism arteriovenous fistula was successfully treated using specialized coils and plug device. Conclusions: Renal arteriovenous fistula is a disease that can lead to serious complications. Treatment of this condition should be initiated promptly after diagnosis. Embolization endovascular is a feasible, efficient and safe method which can maximally retain normal renal function.
