Renal arteriovenous fistula after nephrectomy.
Postnephrectomy renal arteriovenous fistulas are rare. An arteriovenous fistula of the right renal pedicle was discovered in a 37-year-old woman who had undergone nephrectomy for renal tuberculosis nine months previously, after she had complained of dyspnea and pain in the right flank. The fistula was confirmed on arteriograms. Proximal ligation of the artery and distal ligation of the vein were followed by an uneventful recovery. Twelve months later, the patient was asymptomatic. Even though complete excision of the fistula represents the ideal treatment of this type of lesion, simple ligation can provide good results when the size of the fistula contraindicates embolization.
