Spontaneous Accessory Renal Artery Aneurysm Rupture in a Patient With Neurofibromatosis Type 1: A Case Report

Abstract

True renal artery aneurysms are rare. Ruptured aneurysms are even rarer but can have devastating consequences. Renal artery aneurysms most commonly occur in patients with hypertension, atherosclerosis, or fibromuscular dysplasia. Treatment options can range from embolization to nephrectomy. We describe an interesting case of spontaneous accessory renal artery aneurysm rupture in a 44-year-old female with neurofibromatosis type 1 (NF1) who otherwise had no medical problems. She was successfully treated with selective coil embolization, recovered without complications, and maintained preoperative renal function.

Aneurysm of renal artery mimicking as a renal cyst: A case report

“…Aneurysm in accessory or polar renal artery being a very rare condition because only two cases reported so far. Chamberlin and Hovenanian [8] reported aneurysm of accessory renal artery in 1953 and Roberts et al [9] in 2018.…”

A novel NF1 mutation in a pediatric patient with renal artery aneurysm

“…To our best knowledge, there is no other case of RAA in a child with NF1 reported in current literature. A few cases of RAA in adults NF1 patients have been described, often complicated by hypertension [ 8 – 10 ]; spontaneous rupture without risk factors may occur, with four cases reported [ 16 – 19 ].…”

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].…”
