Aneurysmal Type Renal Arteriovenous Fistula With Giant Venous Aneurysm, Mimicking Renal Cell Carcinoma: A Case Report

SummaryBackgroundRenal arteriovenous malformation (RAVM) is a rare disease. The causes of pathological connections between renal arteries may be congenital or iatrogenic – mainly as a consequence of a biopsy or due to renal carcinomas and postinflammatory changes. Computed tomography, ultrasound Doppler and angiography are the main diagnostic tools used for the detection of RAVMs.Case ReportThe aim of this study is to present a case of endovascular treatment of RAVM with a mixture of NBCA and lipiodol. A 29-year-old woman was suffering from drug-resistant hypertension secondary to RAVM. The malformation was embolized using NBCA mixed with lipiodol. The postoperative course was uneventful. A follow-up angio-CT, performed 3 months and one year after the procedure, showed a complete occlusion of the RAVM.ConclusionsNBCA can be used alone to embolize RAVMs. Procedures involving a combination of NBCA and lipiodol are difficult and should be performed by experienced specialists.

Renal arteriovenous malformations and fistula are an uncommon, underdiagnosed condition that can be asymptomatic. However, there is a real risk of rupture and severe bleeding. Imaging techniques have a critical role in planning the treatment. Arteriography is the gold standard but is invasive. Diagnostic selective arteriography can be followed by embolisation of the lesion during the same procedure. Although invasive, because of the potential risk for rupture, arteriography is the elective technique when intervention is planned. We report a rare case of an adult male patient incidentally diagnosed with arteriovenous malformation. Since he had no prior history of renal intervention or trauma, a diagnosis of idiopathic renal arteriovenous malformation was made. We describe the computed tomography findings and management outcome. This asymptomatic, though potentially lethal, condition can be treated with minimally invasive methods.
