腎血管筋脂肪腫に対する動脈塞栓術の1例

CLINICAL EXPERIENCE WITH TRANSCATHETER EMBOLIZATION FOR ANGIOMYOLIPOMA

　69歳，女性．胆石症にて他院で内服治療を受けていたが，発熱，上腹部痛のため入院した．腹部CTにて左腎に周囲血腫を伴い，脂肪成分を含んだ腫瘍を認め，腎血管筋脂肪腫と診断した．我々は，残存する腎実質を温存する目的で経カテーテル動脈塞栓術を施行した．塞栓物質には，ゲルフォーム，金属コイルを用いた．術後7カ月目の現在，異常は認めていない．塞栓術は有効な保存療法の一つと考えられる．

A 69-year-old woman was admitted to our hospital suffering from fever and upper abdominal pain. Abdominal CT scan disclosed left kidney tumor, which contained fat and was accompanied- with hematoma. Rupture of angiomyolipoma (AML) of left kidney was diagnosed. Transcatheter selective embolization of AML was performed to preserve normal renal parenchyma. Gelfoam and coil were used as embolization material. The patient has been followed up uneventfully for 7 months. Embolization seems to be an effective conservative therapy for AML.
