microsurgical venous pouch arterial-bifurcation aneurysms in the rabbit model: technical aspects

破裂人間の脳動脈瘤のために血管内塞栓術は動脈瘤のクリッピングに相当する代替手段となっています。1しかし、大規模臨床試験は、動脈瘤の再疎通と遅延動脈瘤の破裂の受け入れ率が高いと期待はずれの長期的な結果を示している。2これらの問題を克服するために、動物実験的研究より血管内デバイスの開発に不可欠である。3-5 ラット、ウサギ、イヌおよびブタにおけるいくつかの動物モデルが用意されています。異なる動物モデルの6-8の比較は、血行動態と血液凝固系の比較可能性と費用対効果に関して、ウサギのモデルの優位性を示した。9-11 ウサギにおける静脈袋動脈分岐部のモデルは、両方の総頸動脈（CCA）の人工的に作られた真の分岐に縫合静脈袋によって形成される。このモデルの主な利点は、真のbifurcational血行動態です。12の主要な欠点は、最大50％のSOFAR高い顕微技術的な要求と高い罹患率と死亡率である。13これらの制限は、最近ではこの動脈瘤モデルのあまり頻繁に使用されている結果になった年。これらの欠点が改善された外科的処置で克服し、周術期および術後鎮痛管理と抗凝固療法を変更することができます。14から16まで私たちの技術は動脈分岐部動脈瘤の顕微作成のためのこの最適化技術を実証するこのホワイトペーパーで報告。
