Arteriovenous fistula as a complication of renal biopsy.
BACKGROUND
We evaluated the incidence and history of arteriovenous fistula (AVF) after kidney biopsy and assessed the use of superselective embolisation for treatment.


METHODS
Case report of a 10-year-old boy with nephrotic syndrome. Renal biopsy (RB) in this patient was complicated with AVF. Immediately after RB was undertaken, microscopic haematuria was observed, within 48 hours after the biopsy life-threatening haematuria due to pseudoaneurysm started. Renal angiography was carried out, which demonstrated a hyperthrophic aberrant artery in the region of the bottom pole of the left kidney, from which blood was instantaneously flowing through a high-flow arteriovenous fistula (AVF).


RESULTS
Embolization was carried out using small platinum coils (MWCE-18S-3/2, -18S-4/2, -18S-5/2TORNADO Embolization Microcoil) and the tissue adhesive Histoacryl.


CONCLUSIONS
The technique of superselective embolisation using coaxial catheter is a safe method in the treatment of post biopsy AVFs and pseudoaneurysm (Fig. 3, Ref. 6).
