Is a renal artery aneurysm serious?
Renal artery aneurysms (RAAs) are a rare occurrence, with an incidence of about 1% (1, 2). Most patients are asymptomatic and are diagnosed through incidental findings on imaging. In rare instances, the aneurysm can rupture and cause significant morbidity and mortality.
Can you have an aneurysm in your renal artery?
A renal artery aneurysm is a bulge or “balloon” that forms in the wall of an artery that travels to a kidney. In most cases, there are no symptoms associated with renal artery aneurysms, and they are often discovered accidentally during examinations for other medical conditions.
What is the most common cause of renal artery aneurysm?
Renal Artery Aneurysms Most are asymptomatic. The most common cause is typically fibromuscular dysplasia. Other etiologies include degenerative disorders, trauma, and vasculitis. Treatment is generally recommended for any RAA greater than 2 cm.
How common are renal artery aneurysms?
Renal artery aneurysms (RAAs) are uncommon, occurring in approximately 0.09% of the general population. Most clinicians will likely encounter this entity as an incidental finding, as more frequent magnetic resonance imaging, computed tomography, and arteriographic studies are being performed for other diseases.
Is renal artery aneurysm curable?
RAAs can be repaired either with endovascular repair or open surgery. Endovascular repair is a minimally invasive procedure that’s done inside your blood vessels. This has advantages over open surgery, as there’s a lower risk of major adverse effects and shorter recovery time.
How fast do renal artery aneurysms grow?
Results: The baseline mean diameter was 20.1±8.4 mm (range: 9.9–41). The mean follow-up period was 3.13±2.1 y (range: 0.5–7.1). The median growth rate was 0.35 mm/y (interquartile range: 0.05, 0.62). The growth rate was slower when the initial diameter was <20 mm than when it was >20 mm (p=0.036).
How is renal artery aneurysm treated?
Small (< 2 cm) aneurysms in nonpregnant patients may be followed with serial imaging. Traditionally, RAAs are treated with surgery either through aneurysmorrhaphy, resection and bypass grafting, ex vivo repair, or nephrectomy.
How do you fix a renal aneurysm?
How is a kidney aneurysm treated?
Treatment for renal artery aneurysm Because of the increased risk for rupture (bursting), a renal artery aneurysm in a pregnant woman or a woman of child-bearing age will generally be treated surgically.
