腎血管筋脂肪腫自然破裂症例に対する経カテーテル動脈塞栓療法

TRANSCATHETER EMBOLIZATION OF RUPTURED ANGIOMYOLIPOMA

　小口径のバルンカテーテルを超選択的に腫瘍栄養動脈に挿入し無水エタノールを注入することによつて，永久的腫瘍塞栓に成功した結節性硬化症に合併した腎血管筋脂肪腫自然破裂の1例を報告した。結節性硬化症に合併する腎血管筋脂肪腫は両側性，多発性である頻度が高く，腫瘍からの出血に対しても正常腎組織を可能な限り温存し得る治療法が望まれるが，本法は手技が容易で侵襲性も低く，最適な方法と言えるかもしれない。

A case of ruptured angiomyolipoma associated with tuberous sclerosis was reported. Superselective embolizaton of the tumor was successfully performed, preserving normal renal tissue. Ethanol was used as embolic material, because it almost entirely precludes recanalization of embolized vessels and development of collateral channels. As bilateral or multifocal development of tumors is frequent, management of ruptured angiomyolipoma should be done conservatively by superselective transcatheter arterial embolization.
