高齢者破裂脳動脈瘤に対する手術適応

貫井英明

 現在までに経験した破裂脳動脈瘤例618例において、60才以上を5才毎に3群に分け、59才以下の群を加えた4群で手術成績を比較、分析し、高齢者における手術適応基準を検討した。
 その結果一部の例外を除き、高齢者においても若年者とほぼ同様の手術成績がえられることが判明した。
 従って、高齢者においても、出血前正常な日常生活が可能で重篤な全身合併症を有しない Hunt & Kosnik 分類の Grade I〜IVの例、という若年者同様の手術適応基準で良いと考えられた。
 また上記の手術適応基準を満した場合は年令的限界はなく、手術時期は出血後可及的早期が良いと考えられた。
 さらに高齢者における手術手技および術後管理上の注意点についても述べた。

Indication for surgical treatment in
elderly cases with ruptured cerebral aneurysms

Hideaki NUKUI

Indication for surgical treatment in elder1y patients with ruptured cerebral aneurysms was investigated by analysis of the results of the operation for 618 cases. Cases were divided into 4 age groups as follow : under 59 years, 60-64 years, 65-69 years and over 70 years. The result, which were correlated with clinical grades just before operation and timing of the operation, were compared between respective group. From these analyses, the similar results were obtained in each age group with small number of exception. Data allowed us to conclude that the surgery of treatment for ruptured cerebral aneurysms in elderly patients should be the choice without upper limit of age, as well as in younger cases, if patients were able to make a normal daily life without severe complications before the bleeding and were classified into grade I〜IV of Hunt & Kosnik's classification preoperatively. It is also recommended that the operation should be carried out as soon as possible after the bleeding in elderly.
