“…However, these data were based mainly on mid-term follow-up of small RAAs, with a mean diameter of 20 mm, and considering the age of these patients, the operative treatment is indicated in RAAs larger than 25 mm. In giant or symptomatic RAAs, especially if a high flow AVM exists, the risk of an imminent rupture is very high, and urgent surgical repair is fully advocated [ 8 - 10 ]. Two types of renal AVMs have been recognized, the cirsoid with multiple small and dilated arteriovenous communications and the aneurysmal type, which consists of a single arterial communication with a solitary vein.…”

“…However, a simplified classification system was recently proposed by Rundback et al [ 15 ], which described three types of RAAs and facilitated the decision-making regarding the operational treatment options [ 15 ]. Type I is a saccular aneurysm arising from the main renal artery or a proximal large segmental artery and represents the ideal place for endovascular treatment with covered stenting with or without adjacent embolization [ 8 , 10 , 16 ]. Type II is fusiform aneurysm involving the renal artery bifurcation.…”

Renal artery aneurysms (RAAs) are rare lesions with a prevalence of less than 1% in the general population. Renal arteriovenous malformations (AVMs) are rare lesions with an estimated incidence of less than 0.04%. The coexistence of these two clinical entities is extremely rare and narrows the available treatment options by endovascular or open surgery. We describe a case of a giant symptomatic RAA type III, which was combined with a high-flow renal AVM in the right kidney. Using two vascular plugs, the RAA was excluded successfully. The perfusion of the right kidney's lower pole was preserved by implantation of two covered stents in the inferior segmental renal artery.

“…If needed, reintervention by endovascular techniques is usually simple. The effectiveness and safety of endovascular embolization to treat RAAs has been the focus of many studies since 1995 [ 7 , 8 , 9 , 30 , 32 ]. In early publications, effectiveness was good, but the complication rate remained high, due chiefly to the intrinsic limitations of the material available at the time [ 46 , 47 ].…”

“…Although no strong recommendation exists concerning the indications for RAA treatment, symptomatic aneurysms and aneurysms larger than 1.5 cm are usually deemed to require intervention [ 1 , 2 , 3 , 4 , 5 , 6 ]. Multiple clinical studies have assessed the efficacy and safety of endovascular treatment versus surgical repair [ 7 , 8 , 9 , 10 ]. The choice between these two options is generally based on the location and morphology of the aneurysm.…”

The endovascular treatment of renal artery aneurysms (RAAs) has lower morbidity and shorter stay lengths compared to surgical repair. Here, we describe coil packing with or without remodeling and assess outcomes and complications. We retrospectively identified the 19 consecutive preventive endovascular RAA coil embolizations done in 18 patients at our center in 2010–2020. Patient and aneurysm characteristics, technical success rate, complications, and recurrences were recorded. Mean patient age was 63 ± 13 years. The RAA was >1.5 cm in 11 cases, and in four cases, the aneurysm-to-parent artery size ratio was >2. Simple coiling was performed for 11 (57.9%) aneurysms, stent-assisted coiling for seven (36.8%) aneurysms, and balloon-assisted coiling for one (5.3%) aneurysm. Technical success rate was 100%. Complete definitive RAA exclusion was achieved with a single procedure for 17 (89.5%) aneurysms, whereas two (10.5%) aneurysms required a repeat procedure. Four minor complications occurred but resolved with no long-term consequences. No major complications occurred during the mean follow-up of 41.1 ± 29.7 months. Coil embolization by sac packing or remodeling proved very safe and effective. Together with the known lower morbidity and shorter stay length compared to open surgery, these data indicate that this endovascular procedure should become the preventive treatment of choice for RAAs.

“… 1 According to the morphology and anatomical location, RAAs can be categorized into four subgroups: saccular, fusiform, dissecting, and intrarenal. 4 , 5 Depending on the lesion location and shape, another popular classification (Rundback’s classification) divides RAAs into three types: type I is a saccular aneurysm arising from the main renal artery or a large segment branch; type II comprises fusiform aneurysms involving renal artery bifurcations; and type III comprises intralobar artery aneurysms. 3 , 5 , 6 Herein, we describe a rare case of type I RAA, which is also called a hilar RAA (HRAA).…”

Endovascular therapy for distal hilar renal artery aneurysm: a case report and literature review

Renal artery aneurysm (RAA), a type of visceral aneurysm with atypical symptoms, is difficult to detect and is usually discovered incidentally by imaging examination. Hilar RAA (HRAA) represents a relatively rare subgroup of RAA that is located in the distal part of the renal artery, close to the renal parenchyma. We reported a 55-year-old woman with an HRAA measuring 19 mm × 20 mm × 20 mm. She underwent endovascular therapy with bare-metal stent implantation with nested coil embolization. She was discharged without complications. The uniqueness of this case is the aneurysm location, which was at the distal right renal artery, making it difficult to preserve the blood supply to the right kidney. The novelty of the minimally invasive technique was that this endovascular treatment not only eliminated the aneurysm, but also preserved the blood supply to the ipsilateral kidney. Endovascular therapy is effective in the management of HRAA.
