痙攣性斜頸にみられた蜘網膜癒着について

ON ARACHNOID ADHESION OBSERVED IN CASES OF SPASMODIC TORTICOLLIS

まえがき

　痙攣性斜頸は比較的まれな疾患であり，またその本態は古くは，ヒステリー乃至は神経症として官能性疾患の中に入れられていたが，錐体外路系の知見の拡大と共に，錐体外路系とくに線状体障害による運動亢進症と考えられるようになつた。

　その後Tretiakoff, Cassirerや木城^7）氏等により本症の剖検例も報告せられている。

D. Jinnai, A. Nishimoto, K. Fuku, A. Umeda Membraneous arachnoid adhesion of the upper cervical cord was seen in 4 cases among 7 cases which had Olivecrona' operation for spasmodic torticollis. These arachnoid adhesions were obviously pathologic and gave an interesting suggestion in considering the etiology of this disease.

Almost all of the medical and surgical the-rapeutics were ineffective except for Oliver-crona' operation which resulted in complete and permanent relief of this disease in all cases. In one case, the authors cut only the anterior roots of the 1st, 2nd and 3rd cer-vical nerves bilaterally and kept the posterior roots intact. This gave also good results.

In one case, air insufflation in the spinal cavity was very effective and no more sur-gical operation was necessary.
