肋膜腔穿刺に困り惹起せる回歸神經麻痺の1例

　緒言

　回帰神経麻痺は我領域では屡々遭遇する疾患で専門家にとり特に末梢性麻痺に因るものが重要である事は周知の事実であります．余等は最近肋膜腔穿刺に誘因せると思われる回帰神経麻痺の1例を経驗したので此処に報告する．

Ejima and Koyama report during a course of treatment directed at the right side of chest for pleurisy a manifest paralysis of the left recurrent laryngeal nerve took its place.

A man 58 years of age upon hospitalization was being treated on the right by aspiration of accumulated pleural exudates. About 12 hours later the patient complained of dysphonia. Physi-cal examination revealed edema of the right cheat which extended to the cervical region on the same side and the larynx presented a picture in evidence of the paralysis of left recurrent laryngeal nerve. These symptoms gradually sub-sided within period of 3 weeks when larger flow of urine was then established,

The authors believe indirect pressure as arising from the displaced mediastinum due to edematous state of the right chest created a possible positional shift of the aota which in turn caused a temporary pressure upon the recurrent laryngeal nerve to effect its manifest functional derangement.
