AbstractList | In patients with ruptured dissecting aneurysms requiring occlusion of the posterior inferior cerebellar artery (PICA), revascularization of this artery should be performed. We present a novel technique for revascularization of the PICA. After a segment of the superficial temporal artery (STA) was harvested, the aneurysm was treated by trapping followed by placement of a vertebral artery-PICA bypass using the STA as an interposed graft. When the length of the proximal PICA was inadequate, the distal end of the STA was anastomosed to the proximal PICA in an end-to-side fashion. When the length of the proximal PICA was adequate, the STA was anastomosed to the proximal PICA in an end-to-end fashion. In either case, the proximal end of the STA was anastomosed to the vertebral artery in an end-to-side fashion. This procedure was used in 7 patients whose dissecting aneurysms involved the PICA. Although 1 patient developed partial laterally medullary syndrome, follow-up evaluation revealed graft patency in all patients. Although our procedure requires harvesting of a STA graft and 2 anastomoses, it facilitates anterograde flow to the PICA territory. It also involves minimal mobilization of brain stem perforators and the proximal PICA. 後下小脳動脈(PICA)を含んだ脳動脈瘤の治療の際には, PICAの血行再建が必要となる2)5)11)12). 筆者らは, 浅側頭動脈(STA)をinterposed graftとして用いたPICAの血行再建術を1995年に始めてから今日までに12症例に対して施行した6). このうち, PICAを含んだ出血発症解離性動脈瘤7症例に対する同法の有用性について報告する. 対象 症例は, PICAの血行再建が必要であったくも膜下出血発症の椎骨動脈解離性動脈瘤5例と後下小脳動脈解離性動脈瘤2例である. 男性2例, 女性5例, 平均年齢は46歳(32-63歳)であった. 入院時のHunt and KosnikのgradeはIIが4例で, IIIが3例であった. 初期の2例は慢性期に, その後の5例は発症72時間以内の急性期に手術を行った(Table 1). 手術手技 手術は側臥位で後頭下開頭を行い, 解離性動脈瘤の観察を十分に行ったのちにSTAの頭頂枝を約5cm採取する. 解離性動脈瘤の解離部をクリップでtrapする.
