長期生存した原発性橋出血例の経時的な気脳断層写

FOLLOW-UP STUDY OF LONG-SURVIVED PRIMARY PONTINE HEMORRHAGE BY PNEUMOENCEPHALO-TOMOGRAPHY

　原発性橋出血の予後は極めて不良であり，出血発作後3日以内に約80％が死亡するといわれる^3）8）．最近私達はV-Aシャントおよび橋内血腫を摘出した術後に，長期間生存した原発性橋出血を2症例経験しているが^5），これらの症例の退院までの経過中に気脳断層写で脳幹部の経時的な形態の変化を追跡することが出来たので報告する。

A removal of an hematoma and a V-A shunting were carried out in two out of 7 cases of primary pontile hemorrhage. Surgically treated patients survived strokes and were discharged on the 180th and the 352nd hospital day respectively.

A pneumoencephalo-tomogram performed on the 137th hospital day showed a markedly hollowed pons on the affected side in case 1, in whom a V-A shunting was done. Tomograms carried out on the 183rd and the 352nd hospital day demonstrated a marked atrophy of the pons and the cerebellum in case 2, in whom an intrapontine hematoma was removed.
