左鎖骨下動脈閉塞に対する血行再建術を行った後に塞栓術を行った右椎骨動脈解離性動脈瘤破裂の1例  [in Japanese] Endovascular Trapping for a Ruptured Right Vertebral Dissecting Aneurysm after Reconstruction of the Occluded Left Subclavian Artery  [in Japanese]

Abstract

左鎖骨下動脈閉塞のため,右椎骨動脈から左鎖骨下動脈への盗血現象を伴った患者に発生した右椎骨動脈の解離性動脈瘤破裂を経験した.閉塞した鎖骨下動脈にステントを留置して左椎骨動脈の血流を再建した後に,患側椎骨動脈の塞栓術を行った.当院の3D-CT angiography(3D-CTA)では頭蓋内の情報しか得られず,当初は盗血現象や鎖骨下動脈閉塞を把握することができなかったが,血管撮影で病態を把握し対応することができた.3D-CTAのみでクリッピングを行う施設では,本例のような病態も念頭に置き,大動脈弓部から頭蓋内までの情報を得ることが望ましい.それが困難な場合は,超音波検査などの補助診断を併用し,必要に応じ血管撮影も追加施行するべきではないかと考えられた.

The authors describe a case of ruptured right vertebral artery dissecting aneurysm accompanied with left subclavian artery occlusion. Right vertebral angiogram showed the steal phenomenon from left to right. An aortogram revealed that the left subclavian artery was occluded at its origin. First of all we decided to reconstruct the occluded left subclavian artery. A balloon expandable stent was deployed under the temporary balloon occlusion of the left vertebral artery. Regular blood flow from the left subclavian to the vertebral artery was restored after the procedure. Finally, the endovascular trapping of the right vertebral artery including the aneurysm was performed safely with detachable coils.
