“…The indications for endovascular repair have broadened with the introduction of three-dimensional detachable coils, nonadhesive liquid embolic agents (ie, Onyx), remodeling techniques (which include balloon-and stent-assisted coiling), and flow diverter stents (ie, the Cardiatis multilayer stent). 22,24,25 Technical success across larger series have been reported as 73% to 100%, with highly variable rates of morbidity (13%-60%) that include primarily radiographic evidence of end-organ malperfusion from thromboembolism and subsequent postembolization syndrome (Table III). These reported series describe no incidence of access-related complications, arterial dissections, or renal compromise, along with low rates of recanalization requiring reintervention (4%-13%).…”

Renal artery aneurysms are rare in the general population, although the true incidence and natural history remain elusive. Controversy over criteria for repair persists across decades. Indications for repair presently include aneurysm size >2 cm, female gender within childbearing age, symptoms like pain and hematuria, medically refractory hypertension including that associated with functionally important renal artery stenosis, thromboembolism, dissection, and rupture. Conventional surgical reconstruction options are variable and continue to offer technically sound and durable results. Endovascular therapies with novel devices also offer technical success with few major adverse events, and are increasingly employed as indications for intervention broaden. This review summarizes the accumulated evidence on true renal artery aneurysms with a particular focus on contemporary treatment criteria, natural history, options for repair and outcomes following such.

“…Packing can be attempted in aneurysms with a narrow neck, (with stent or balloon assistance as needed). In other cases, embolization by balloon-assisted treatment with ethylene-vinyl alcohol can be performed [30].…”

Visceral artery aneurysms are rare but their estimated mortality due to rupture ranges between 25 and 70%. Treatment of visceral artery aneurysm rupture is usually managed by interventional radiology. Specific embolization techniques depend on the location, affected organ, locoregional arterial anatomy, and interventional radiologist skill. The success rate following treatment by interventional radiology is greater than 90%. The main complication is recanalization of the aneurysm, showing the importance of post-therapeutic monitoring, which should preferably be performed using MR imaging.

“…Gabelmann performed embolization in 25 patients concerning VAAs with a success rate of 92% but with a mortality rate of 4% [35]. In the literature, some more successful endovascular procedures are reported with very small numbers of patients [6,17,24,29,34,[37][38][39][40]. The endoscopic approach to the abdomen had expanded in the field of VAAs as well.…”
