[ANEURYSMAL TYPE RENAL ARTERIOVENOUS FISTULA WITH GIANT VENOUS ANEURYSM, MIMICKING RENAL CELL CARCINOMA: A CASE REPORT]

Endovascular Treatment of Renal Arteriovenous Fistula with N-Butyl Cyanoacrylate (NBCA)

Background

Renal 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 Report

The 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.

Conclusions

NBCA can be used alone to embolize RAVMs. Procedures involving a combination of NBCA and lipiodol are difficult and should be performed by experienced specialists.
