A B C Fig. 1 Case 1 A Initial diagnostic angiogram of the right vertebral artery (anteroposterior view) shows a dissecting aneurysm. B Left vertebral angiogram during vessel reconstruction using a coronary stent. C Angiogram obtained immediately after stent deployment (dotted frame). A B C D E Fig. 2 Case 1 Serial vertebral angiography findings (A) 1 day, (B) 3 months, and (C) 6 months after reconstruction show progressive thrombosis; however, at 1 year (D) the aneurysmal sac is recanalized. Arrows indicate in-flow into the aneurysmal sac. E Angiogram immediately after deployment of a stent in the originally placed stent. Straightening of the parent artery with the stent facilitates flow stagnation in the aneurysm. The normalization of flow direction is shown by estimates of flow direction at each stage (indicated by arrows). 域は同側の AICA が灌流していた BTO にて 20 分間の 留置した 全身ヘパリン化を行った後 ACT=270 秒以 虚血耐性を確認した すでに Aspirin 81 mg の投与を受 上 RapidTransit 150 cm 2 marker および Agility14 soft けていたので さらに Ticlopidine 200 mg を治療 1 週間 にて解離腔を慎重に越えて microcatheter を basilar top 前に追加した に置いた 次いで guidewire を STABILIZER14-300 cm 治療 全身麻酔後 7Fr パトリーブを右 V2 segment に に交換し microcatheter を抜去した 血管内エコー上 JNET Vol.7 No.2 May 2013 113
A B E C Fig. 3 Case 1 Serial MIP (maximum intensity projection) images of 3D-CT (A) 1 day, (B) 3 years, (C) 7 years, and (D) 10 years after stent deployment in the originally placed stent demonstrate progressive thrombosis (arrows). E Saw-like image (arrows) on a right vertebral angiogram 7 years after reconstruction indicates slight protrusion of contrast medium through the stent struts. F Intravascular ultrasound shows neointima formation around the stent struts (arrows). F A D B C Fig. 4 Case 2 A Anteroposterior view of a right vertebral angiogram shows a dissecting aneurysm presenting as Wallenberg's syndrome. B Fluoroscopic image during reconstruction with a coronary stent (between the arrows) shows stasis of contrast medium within the aneurysm. C Angiogram a few minutes after stent deployment shows the straightened parent vessel (white arrow) and persistent stasis of the contrast medium at the venous phase. 114 JNET Vol.7 No.2 May 2013
