To provide a treatment method, a separation method, and a filter assembly capable of restraining a fat-soluble compound such as cholesterol crystals generated during dilation of a stenosed site from causing cholesterol embolism, like so-called Blue Toe syndrome or acute renal failure, in which such a fat-soluble compound clogs in glomeruli of kidneys or peripheral capillaries.SOLUTION: Cholesterol crystals generated from plaque during use of a balloon catheter are taken out of the body and removed using a centrifugal separation device or filter, and usable living cells are returned to the body to reduce blood transfusion and mitigate cholesterol embolism.SELECTED DRAWING: Figure 1 【課題】狭窄部拡張の際に生じたコレステロール結晶などの脂溶性化合物が末梢の毛細血管や腎臓の糸球体で目詰まりを起こしいわゆるコレステロール塞栓症であるＢｌｕｅＴｏｅ症候群や急性腎不全などを引き起こすことを抑制できる治療方法、分離方法およびフィルター組立体を提供する。【解決手段】バルーンカテーテル使用時にプラークから生じたコレステロール結晶を体外に取り出し、遠心分離またはフィルターを用いて除去し、使用可能な生きた細胞を体内に戻して輸血を減らし、コレステロール塞栓症を軽減する。【選択図】図１
