内頸動脈蛇行の眼症状

The Horner's Syndrome by Coiling of Arteria Carotid interna in Neckpart.

I．緒言

　Horner's Syndromeは1869年Claude Ber—nard及びHornerによつて最初報告されたが，頸部交感神経切除術が施行されるに至り本症状群の研究が完成されたかの様に見える。

　しかし乍ら，私共，臨床家にとつては，この症候群の成立機転を知る事は甚だ困難なる場合が多い。外傷，或は，腫瘍の圧迫，炎症の波汲等の場合では比較的容易にその原因を知り得る事も多い。私どもは頸部交感神経がそのCarotid Ple—xusに障害がある場合は頸動脈撮影を行なう事によつて，容易にその病変を把握出来得る場合もあると考えて頸動脈撮影を行なつて，著明な内頸動脈の屈曲蛇行の一例に遭遇した。

A report is given over a case in which elongation and tortuosity of the internal ca-rotid artery caused the Horner's syndrome.

The patient, a 72-year-old female, had been conscicos of left-sided blepharospasm for 2 years and of blepharoptosis for the last one year. The diagnosis of Horner's syndromewas given after recognition of other charac-teristic clinical signs by close examination.

While there were otherwise no positive fin-dings that belong to the known causes of the Horner's syndrome, arteriography revealed that the cervical portion of the left internal carotid was remarkably prolonged and show-ed a C-shaped tortuosity.
