緒言
腎動脈撮影,特に経時的連続撮影法の普及に伴つて,腎内動静脈瘻症例が発見されることが多くなつているが,腎病変に加えて心循環動態に影響を及ぼす特異な病態が注目されている。著者らは,腫瘍腎の血流量および腎静脈血の酸素濃度の検討から,X線上,hypervascularizedの腫瘍腎においては,動脈撮影で動静脈瘻が描出されなくとも,例外なく腫瘍性動静脈瘻の循環動態をとつていることを先に述べた1)。今回は,後天性腎動静脈瘻の中では代表的といわれる腎生検後の動静脈瘻症例を経験したので,ここに報告する。
A case of renal arteriovenous fistula resulting from percutaneous needle biopsy was reported. The patient was 40-year-old female in whom hypertension was discovered during examination inFebruary, 1975. She had been performed needle biopsy of right kidney because of proteinuria in June, 1967. Blood pressure was 170/107 mmHg and urinarysis was positive proteinuria and microscopic hematuria. On auscultation a continuous bruit was heard over the right flank. Chest X-p and electro-cardiogram was unremarkable. Renal arteriography showed an intrarenal arteriovenous fistula.
