副鼻腔手術後偶発した「クモ膜」下出血死の1例について

　はしがき

　鼻の手術に併発する頭蓋内合併症としては，化膿性髄膜炎が多く，その報告も数多く見られるが，直接手術そのものの影響によらざる偶発的と見られるクモ膜下出血は従来その報告例に乏しい。私共は最近副鼻腔手術後第11病日に突然クモ膜下出血をおこし治療に勉めたるも後出血のため死亡した1例を経験し剖検する機会を得たので報告する。

　A case in which the patient died of subarachnoidal hemorrhage following operation on paranasal sinuses is reported. On the 11 th postoperative day, the patient, a man aged 29, began to complain of fever, headache and nausea. Spinal puncture established the diagnosis of subarachnoid hemorrhage. Ten day later there was an onset of another similar hemorrhage in spite of various treatments having been instituted and the patient died. The postmortem examination revealed subarachnoid hemorrhages in the region of optic nerve bifurcation, the third and fourth ventricles as well as the basilar region of the cerebellum; the cerebral tissues approximating optic nerve bifurcation were found to be degenrated. There were no signs of inflammatory involvement of the cranial cavity.
