CONGENITAL RENAL ARTERIOVENOUS MALFORMATION:A CASE REPORT

緒言

　腎動脈造影法の普及に伴い，腎動静脈瘻の報告はここ数年来ふえつつある。われわれは腎動脈造影像と病理組織像にて特徴ある所見がみられたcongenital arteriovenous malformationの1例を経験したので報告する。

A case of left congenital renal arteriovenous malformation in a 33 year-old woman with the chief complaint of sudden grosshematuria was reported.

Intravenous pyelography showed normal kidney and ureter, but retrograde pyeolgraphy disclosed irregurality of left ureteropelvic junction. Angiographic signs included small cirsoid vessels and early venous return, but there was no evidence of displacement of intrarenal vessels and collecting system. The size and weight of the left kidney were normal, but abnormal pelvic submucosal angiomatous vessels and phlebosclerotic changes of interlobar veins were histopathologically elicited.
