Renal Artery Aneurysms

Surgery for Renal Artery Aneurysms: A Combined Series of Two Large Centers

“…Autopsy studies have shown an incidence of 0.01% in the general population while the occurrence of renal artery aneurysm in reported series of patients undergoing selective renal angiography varies between 0.3 and 0.7% [3, 6]. When arteriography is performed during the workup of hypertension, the incidence is 2.5% [4, 7]. …”

“…The incidence of ruptured renal artery aneurysm reported by Stanley et al [4] was 4/72 (5.6%), although a 20% rupture rate has been reported for intrarenal aneurysms [15]. Hageman et al [3] followed 25 patients with renal artery aneurysms less than 2 cm in size for a period of 1–70 years and no ruptured aneurysms were observed.…”

“…With increasing use of angiographic studies, which have estimated the incidence to be between 0.3 and 0.7% [1, 2, 3, 4] and, consequently, operative management, more is known about this entity of renovascular disease. Because of the many still unanswered questions about its prognosis, and the surgical challenges it poses, a retrospective review of two large centers treating patients with renal artery aneurysms was conducted.…”

Renal Cell Carcinoma Associated with Renal Artery Aneurysm

“…Atherosclerotic in volvement with calcifications seems to be a secondary event. They may reach considerable size, often remaining asymptomatic and being discovered incidentally [5,6]. Fusiform aneurysms are uniform dilatations of the renal artery, or of one of its branches.…”

“…On the other hand, aneurysms of the renal artery' were documented in 0.3 and 0.9% of patients of two large series of patients undergoing abdominal aortography for nonrenal diseases [5,6].…”
