Background Achieving rapid and complete reperfusion is the ultimate purpose for ischemic stroke with large vessel occlusion (LVO). Although mechanical thrombectomy (MT) had been a proverbially important procedure, medium (MeVO) thrombus migration can sporadically occur after MT. Moreover, safe effective approach such unknown. We reported thrombolysis intraarterial urokinase MeVO Methods included 122 patients who were treated by MT LVO at our institution between April 2019 March 2021. Of 26...
小児のpial arteriovenous fistula(AVF)は稀な疾患であるが,静脈圧の上昇により頭蓋内出血を来し得るため,予防的治療が考慮される.治療待機中にくも膜下出血を呈した,小児pial AVFの1例を報告する.症例は6歳女児,頭痛精査で施行されたMRIで脳幹背部に異常血管を指摘された.DSAを施行し,左後下小脳動脈を流入血管,深部静脈を流出血管とするpial AVFの診断となった.Drainerはvarixを伴っており,出血リスクが高いと考えられた.脳血管内治療の方針としたが,待機中に意識障害を伴うくも膜下出血で緊急入院となった.再出血予防と減圧のため,直達術によるshunt離断とvarixの摘出を行った.周術期合併症はなく,mRSスコア1で自宅退院となった.Pial AVFに対する直達術においては,血管構築の十分な理解とshunt pointの確実な閉塞が重要と考えられる.
Extracranial carotid artery aneurysms are relatively rare. We present a case involving giant aneurysm arising from the extracranial artery. The patient was 79-year-old woman. She had pulsating mass in right side of her neck. However, she neurologically intact. Contrast-enhanced CT scans neck showed an enhanced lesion with thrombus Angiography revealed saccular 3.4 cm size near bifurcation site common into external underwent urgent resection and reconstruction. Postoperatively, recovered well...
Abstract Eighty-two year old woman developed motor aphasia. A brain MRI revealed an (1) extramedullary tumor adhering to the dura mater which enhanced almost uniformly and (2) intramedullary in left frontal lobe. She underwent surgery we removed both tumors. Pathological examination that was meningothelial meningioma, WHO grade 1, without malignant findings. had a high cell density, many mitosis (about 15 10 high-power fields), MIB-1 index, leading atypical 2. In addition, osteosarcoma...
当院では,前方循環に位置する通常サイズ未破裂脳動脈瘤の開頭術においては,積極的に若手に術者を担わせ指導医が助手鏡から指導するいわゆる'Two-Surgeon-Three-Hand Surgery'(以下,three-hand surgery)を行ってきた.近年は神経外視鏡の導入により,助手も術者と同様の3次元モニターを使用することになり,明るく広い術野を得ることが可能となった.当院のthree-hand surgeryにおける術中トラブル回避と対処法について,前方循環脳動脈瘤クリッピングを対象に報告する.
大型/巨大内頚動脈瘤に対する直達手術では,特にC1部の動脈瘤を中心に,しばしば良好な機能予後や根治性が得られない場合がある.当施設で2014年から2018年までに開頭手術により治療を行った15mm以上の内頚動脈瘤32例を対象とし〔C3-5部:17例,C2部(C2-3を含む):7例,C1部(C2-3部を含む):8例〕,治療方法,治療成績を後方視的に解析し,問題点を検討した.転帰は半年後のmodified Rankin Scale(mRS)を用いて評価した.C3-5部では,全例でEC-RA-M2バイパス+頚部内頚動脈結紮によるflow...
