Abstract
Renal artery aneurysms (RAAs) are rare but harbor serious consequences if they rupture. When determining if a RAA should be treated, physicians consider aneurysm size as it pertains to the likelihood of rupture. Giant RAAs have rarely been reported in the literature and have usually been managed by open aneurysmectomy and nephrectomy. In the present case, we report a 63year-old male incidentally found to have a giant aneurysm of his right segmental and interlobar arteries on computed tomography (CT). The patient underwent successful uncomplicated transcatheter coil embolization of his aneurysm and maintained no flow into the aneurysm with normal renal function seven years following the procedure.
Highlights
Renal artery aneurysms (RAAs) are reported to occur in approximately 0.1% of the general population [1]
We present the case of a 62-year-old male with a giant aneurysm of his right segmental and interlobar artery, who underwent successful endovascular exclusion of the aneurysm by transcatheter coil embolization
While the evaluation for RAAs may be prompted by symptoms such as hematuria, flank pain, or hypertension, the frequency with which asymptomatic RAAs are being discovered as incidental radiologic findings is increasing, owing to more frequent use of magnetic resonance imaging (MRI), computed tomography (CT), and arteriography
Summary
Renal artery aneurysms (RAAs) are reported to occur in approximately 0.1% of the general population [1]. A follow-up angiogram detailed a large hyperattenuating aneurysm at the right renal hilum appearing to originate from a lower pole branch of the renal artery In an effort to minimize the loss of normal parenchyma, it was recommended that the patient undergo a coil embolization procedure to facilitate thrombosis of the aneurysm. If he were to fail this management, plans were made to proceed with either surgical repair of the aneurysm or a right nephrectomy. The patient will be followed at our institution annually with scheduled office visits and CT angiography
