鎖骨下動脈狭窄症に対する経皮的血管拡張術

Percutaneous Transluminal Angioplasty for Subciavian Artery Stenosis

I．はじめに

　1964年DotterとJudkins^8）によって導入されたper—culaneous translumianl angioplasty（以下PTAと略す）の技術は，1974年Grüntzig^14）のdilatation ballooncatheterの考案により種々の末梢動脈に応用され飛躍的な発展をとげてきたが．brachiocephalic arteriesに対する応用はいまだ日も浅く症例数も少ない現状にある．

　われわれはsubclavian steal症候群を呈した左鎖骨下動脈狭窄症患者に対してPTAを施行し，短いfollow—up期間ではあるが良好な結果を得たので，文献的考察を加えて報告する．

The technique of percutaneous transluminal angio-plasty (PTA) that was introduced initially by Dotter and Judkins in 1964 has been applied to various arterial stencses and some occulusive lesions and has advanced dramatically with the development of the Grüntzig catheter in the treatment of peripheral vascular disease. However, the application to oc-clusive disease in brachiocephalic arteries is still considered to be disputable and has been made only in selective cases, especially in Japan.

We report here a case with stenosis of the left subclavian artery successfully treated with PTA.
