脳室内腫瘍について

ON THE 2 CASES OF VENTRICULAR TUMORS

　脳室内腫瘍は一般に症状が不定で脳圧亢進症状だけの事が多く，臨床上，神経学的検査のみでは診断のつき難いものである。最近は脳室撮影並びに血管撮影が安全容易に行われるようになり報告例も増加した。その治療成績も従来は必ずしも良くなかつたが，最近の麻酔法の進歩，術後処置就中持続脳室ドレナージ及び下垂体副腎皮質ホルモン剤の使用等の進歩により治療成績も陶上した^5）。

　我々は最近，側脳室内腫瘍及び第三脳室内腫瘍の各1例を経験したので報告する。

Two cases of ventricular tumors were reported. The 1st case was meningeoma in the left lateral ventricle, cured by total extir-pation and the 2nd case was astrocytoma in the third ventricle, cured by subtotal extir-pation. In the 1st case, cerebral angiogramshowed tumor configuration in the region of A. chorioidea anterior, and the 2nd case was diagnosed by ventriculography and by ven-triculoscopy. Using hypothermic anesthesia, these 2cases were operated without difficulty because of no cerebral swelling and slight haemorrhage. Using permanent ventricular drainage after ventriculography or tumor extirpation, the postoperative course was satisfactory. After intraventricular injury, suprarenal hormone therapy was necessary and in our 2 cases, temperature returned to normal with medrol or with predonine 2 or 3 weeks after operation.

We emphasize the hypothermic anesthesia, permanent ventricular drainage and suprare-nal hormone therapy were very important in the operation of ventricular tumors.
