腰動脈塞栓術で著効をみた腎癌腰椎転移症例

TRANSCATHETER EMBOLIZATION OF LUMBER ARTERIES AGAINST METASTATIC VERTEBRAL LESION OF RENAL CELL CARCINOMA: A CASE REPORT

緒言

　近年，悪性腫瘍に対する動脈塞栓術が広く行われるようになつてきた。泌尿器科領域では腎腫瘍に対し，手術時の出血を減少させる目的で行われはじめたが^1），適用範囲が広がり^2），塞栓物質にも工夫が加えられるようになつた^3）。

　われわれは最近，腎細胞癌の腰椎転移に起囚する柊痛の軽減を目的に腰動脈の塞栓術を行い，著効を得た患者を経験したので報告する。

A 58-year-old man underwent radical nephrectomy for renal cell carcinoma in January 1979. He was well until January 1982, when he complained of lumbago. An oral lentitive was used regularly for relief of pain. In July 1982, he complained of muscle weakness of left lower extremity and had claudi-cation. Computed tomography revealed destruction of the body of the 4 th lumber vertebra.

In September 1982, the left 3 d and 4 th lumber arteries, feeding the metastatic lesion, were embo-lized with Gelfoam and 10 mg of mitomycin C. Adamkiewicz artery was not visualized by angiography performed prior to the embolization.
