先天性腎動静脈瘻の2例

TWO CASES OF CONGENITAL RENAL ARTERIOVENOUS FISTULA

緒言

　腎動静脈瘻は1928年Varelaの剖検例の報告が最初とされ^1），以後の報告はあまりみられなかつたが，近年腎血管造影法の普及に伴い，その報告例が増加している。今回われわれは肉眼的血尿を主訴とした先天性腎動静脈瘻の2例を経験したので報告する。

Two cases of congenital renal arteriovenous fistula in 26 and 43 years old women were reported.

Both cases were seen with asymptomatic gross hematuria without any cardiovascular symptoms. Physical examination, laboratory data, cystoscopy, and excretory urogram were normal in both cases. In case 1, the arterial stage of renal angiogram demonstrated cirsoid type arteriovenous fistula of the right kidney with early venous return. Angiogram of case 2 demonstrated similar findings. Nephrectomy was performed in both cases.
