Endovascular Treatment of Ruptured Renal Artery Aneurysm: A Case-Based Literature Review

Abstract

Renal artery aneurysms are extremely uncommon with a reported incidence of less than one percent in general population. They are being more frequently detected due to increasing availability and use of abdominal imaging. Renal artery aneurysm rupture is an extremely unusual cause of acute flank pain with hemodynamic instability. Given the rarity of diagnoses, clinicians may not consider and address this ruptured renal artery aneurysm early which can potentially lead to adverse clinical outcomes. We report the case of a 55-year-old male who presented with retroperitoneal bleeding from a ruptured aneurysm of the interlobular branch of renal artery. He was endovascularly treated with coil embolization. We have also reviewed the inherent literature.

Giant Renal Artery Aneurysm With Hydronephrosis and Severe Atrophy of the Renal Parenchyma: Case Report and Literature Review

“…The endovascular treatment has 2 main objectives: the occlusion/exclusion of the aneurysm and the reestablishment of the vascular patency in order to salvage the kidney. 12 , 45 In the case of our patient, the aneurysm was already almost occluded by thrombosis and there was practically no left kidney parenchyma left to be salvaged. The risk of rupture was relatively low in this patient, as the aneurysm was almost completely thrombosed.…”

Combination of Sac packing and liquid embolization using Double Microcatheter Technique for Renal Artery Aneurysm: A Case Report

“…Aneurysm clipping, aneurysmal parent artery resection, angioplasty, and bypass grafting are the most classical treatment modalities with high success rates and low complications [16][17][18][19][20]. A review of the literature over the last 4 years shows that renal aneurysms are increasingly treated with endovascular techniques [11,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] (Table 2). The techniques used in endovascular therapy are varied, including endovascular coiling, remodeling techniques (such as balloon-and stent-assisted coiling), covered stent implantation, and flow diverter [8,21,[40][41][42][43][44][45].…”

Renal Artery Embolization for Neoplastic Conditions

“…4 For this reason, along with fewer complications and more rapid recovery compared with surgical management, RAE is considered the treatment of choice for acute renal hemorrhage when possible. 5,6 RAE can also be performed for a wide variety of nonemergent renal conditions. Patients with end-stage renal disease and consequent drug-resistant hypertension may be appropriate for RAE as a means of functional exclusion of the kidney, particularly those who are poor surgical candidates.…”
