Case Discussion

Renal artery aneurysms are secondary to dysplastic lesions (60-70%), atherosclerotic (30-40%) and arterial inflammatory (1-2%). Although hypertension is present in 70% of patients with renal artery disease, it is believed that this is due to an aneurysm in only a small percentage of cases ( 5%).

The disorders that can cause are rare: sometimes coexists a state of hypertension pain in the lumbar region and hematuria.

The majority of renal artery aneurysms are asymptomatic and are discovered accidentally, however, as a result of diagnostic tests for hypertension, for arterial occlusive disease of the lower limbs or aortic aneurysm (Doppler ultrasound, MRI, angiography).

The risk of rupture is significantly increased in women during pregnancy, with a mortality rate that reaches 80%, both maternal and fetal. Aneurysms with a diameter greater than 1.5 cm and associated with hypertension should be easier to rupture.

The indication for surgery is intended for aneurysms with a diameter > 1.5 cm in hypertensive patients, especially in young females of childbearing age.
