Congenital and Acquired Renal Arteriovenous Malformations: Curative Embolization with Onyx

et al. 2016

Renal arteriovenous malformations are rare, as is their embolization with Onyx. Endovascular curative embolization of renal arteriovenous malformations with Onyx is a relatively new procedure. Herein we present two cases of congenital and one case of acquired renal arteriovenous malformation embolized with Onyx 18 and their good results in the follow-up period. We used detachable microcatheters, which may be more advantageous than the nondetachable ones, during the superselective embolizations. Onyx, as an efficient embolic material, can be commonly used for curative embolization of the renal arteriovenous malformations.

Large congenital renal arteriovenous malformation treated with interlock coil embolization

et al. 2013

Renal vascular malformation is an abnormal communication between the intrarenal arterial and venous system. These malformations include arteriovenous malformation (AVM) and arteriovenous fistula (AVF). 1 Renal AVM is a congenital developmental abnormality in which the renal artery and renal vein communicate through a network of abnormal vessels. By contrast, renal AVF is a direct communication between an artery and a vein. The etiology of congenital AVM is unknown, while the cause of acquired renal AVF is usually found to be percutaneous renal biopsy, other procedures, and incidental renal trauma.A 57-year-old woman visited our hospital with intermittent left flank discomfort of several years' duration. The symptom had worsened with position change and had become particularly bothersome during the preceding few months. She had no past medical history including trauma or procedures. On physical examination, a continuous bruit was audible over the left flank area. Urinalysis and blood tests showed normal findings. A contrast-enhanced computed tomography scan of the abdomen demonstrated aneurysmally dilated enhancing vessels with attenuation similar to the arteries in the left kidney (Panel A). Digital subtraction arteriography showed a feeding artery to a large AVM with abnormal dilation of the nidus and early opacification of venous flow (Panel B1). In this patient, the large AVM was treated with interlock coils (Panel B2). After super-selective catheterization, coil-embolization of all feeders was performed successfully (Panel B3). Magnetic resonance imaging (MRI) before treatment presented aneurysmally dilated vessels with high flow and suggested an underlying vascular malformation (Panel C1). A followup MRI taken 6 months post-embolization showed successful occlusion of the AVM with coils (Panel C2).In this case, AVM was managed with deployment of coils into the vascular malformation, which promoted thrombosis. 2 Complications can arise from the rapid shunting of the coils into the venous circulation, leading to emboli entering the pulmonary circulation or the left side of the heart if interarterial communication exists. Blocking the venous output of the AVM can help in preventing this complication. It is also important for the angiographer to be familiar with retrieval techniques if such a complication arises. 3
