破裂解離性椎骨動脈瘤に対する血管内治療 : その有用性と最近経験した合併症からの教訓  [in Japanese] Endovascular Treatment of Ruptured Vertebral Artery Dissecting Aneurysms : Its Usefulness and Lessons from Complications  [in Japanese]

Abstract

破裂解離性椎骨動脈瘤(vertebral artery dissecting aneurysm:VADA)は比較的まれとされてきたが, 近年その報告は増加しており, 従来言われてきたよりも頻度の高い疾患であるとの認識が拡がっている. また急性期の再出血の頻度が非常に高いこと, および再出血による予後の悪化が指摘されており, 早期診断, 早期治療の重要性が強調されている. われわれは, 破裂VADAに対して超急性期に血管内手術を第一選択として治療してきたのでその有用性と, 最近経験した合併症から学んだ教訓につき報告する. 対象と方法 2000年1月から2004年2月までの期間に治療した出血発症のVADA連続32症例を対象とし, 年齢, 性別, 術前状態, 術前再出血の有無, 合併症, 転帰などをretrospectiveに検討した. 実際の治療に関しては, CTによるくも膜下出血の診断確定後, 患者の状態が許せば脳血管撮影にて動脈瘤の部位診断を可及的早期に行うことを原則としている.

We evaluated the cases of 32 consecutive patients with ruptured vertebral artery dissecting aneurysm (VADA) treated in our institution during the last 4 years. The goal of treatment was to exclude the aneurysm from the circulation using Guglielmi detachable coils (GDC). Twentysix out of 32 patients were treated within 24 hours of the initial rupture, but 17 had rebleeding before treatment. The outcome of the patients depended greatly on the patient's condition (Hunt &Kosnik grade) before treatment and whether there was rebleeding. There were 4 complications including I case of intra-operative rupture, 2 cases of rebleeding after treatment, and 1 case of cerebral infarction. The lessons from these complications would benefit from further treatment. Although this report does not describe a controlled study, we found that endovascular treatment is preferable for treating ruptured VADAs in the acute stage.
