Renal Arteriovenous Fistula Following Puncture Biopsy: A Hemodynamic and Functional Study in Four Cases

Abstract

Abstracr. Four cases of arteriovenous fistula in ths renal parenchyma following percutaneous renal biopsy in uremic patients are described. The effect cn ths renal blood flow was studied with a dye-dilution technique. Although in all cases the fistulas were located peripherally in ihkidney, a considerable redistribution of ths blood flow could be demonstrated, resulting in decreased flow through the renal parenchyma. The diminished blood flow gave rise to decrtastd function of the affected kidney.
