Cell transplantation therapy offers great potential to improve impairments after stroke. However, the importance of donor age on therapeutic efficacy is unclear. We investigated regenerative capacity transplanted cells focusing (young vs. old) for ischaemic The quantities human mesenchymal stem cell (hMSC) secreted brain-derived neurotrophic factor in vitro and monocyte chemotactic protein-1 at day 7 vivo were both significantly higher young hMSC compared with old hMSC. Male Sprague-Dawley...
Aneurysm rebleeding is a major cause of death and morbidity in patients with aneurysmal subarachnoid hemorrhage (SAH). Recognizing the predictors might help to identify who will benefit from acute management. This study was performed investigate aneurysm their impact on clinical outcomes preoperative, intraoperative, postoperative periods.
Cranioplasty of cranial bone defects can generally be accomplished with autogeneous bones as well nonbiological materials. Autologous living-bone grafts are ideal but require sacrifice donor bone, and synthetic materials might have possible exposure the materials, delayed infection, and/or allergic reaction. The authors report cranioplasty a graft after auto-purification by subcutaneous preservation contaminated fragment. A 47-year-old man was given frontal split parietal rib. Epidural...
Background: Minimally invasive surgical techniques for cerebral aneurysms have been developed.Aims: To compare the efficacy and safety of modified mini-pterional (mMPT) standard pterional (PT) craniotomies ruptured anterior circulation aneurysms.Materials Methods: A total 45 patients with underwent clipping; 21 PT was used 24 mMPT used. Initial clinical demographics outcomes were retrospectively compared. systemic inflammatory response syndrome (SIRS) score derived by summing number...
【目的】我々は頚部内頚動脈高度狭窄に起因する頭蓋内内頚動脈閉塞（tandem occlusion）を来した急性期脳梗塞症例を経験したため報告する．【症例】59 歳女性．右片麻痺と失語を主訴に発症から2 時間で救急搬送された．頭部MRIでclinical-diffusion-weighted image mismatch を認める左内頚動脈閉塞を認め，血管内治療を行った．頚部左内頚動脈高度狭窄の合併を認め，頚動脈ステント留置後に頭蓋内再開通療法を計画した．ステント留置後にpenumbra systemを使用し，発症より7 時間40 分で有効再開通が得られ，症状は改善した．【結論】頚部内頚動脈高度狭窄と頭蓋内内頚動脈閉塞症に対してcarotid artery stenting（CAS）とthrombectomy を行い，良好な治療経過を得た．頚動脈狭窄に起因した頭蓋内主要血管閉塞症に対してemergent CAS とthrombectomy は有用である．
Arteriovenous fistula (AVF) occurring within the craniocervical junction (CCJ) is an uncommon vascular anomaly. A 56-year-old man presented with cervical pain and gait disturbances. Computed tomography revealed a hematoma in epidural space at spinal level. Subsequent cerebral angiography shunt CCJ, leading to diagnosis of AVF (EDAVF). Transvenous embolization, performed under general anesthesia, successfully resolved shunt. Transarterial embolization CCJ-EDAVFs carries substantial risk...
Abstract INTRODUCTION Primary central nervous system lymphoma (PCNSL) is characterized by an extremely high proliferation rate, making early diagnosis and therapeutic intervention crucial. To facilitate rapid diagnosis, our hospital has implemented flow cytometry (FCM) in addition to conventional histopathological methods. We evaluated the effectiveness of FCM for PCNSL. METHODS From 2010 2023, we retrospectively analyzed 67 consecutive patients with suspected PCNSL based on preoperative...
Invasive sphenoid sinus aspergillosis is a rare infection and usually affecting immunocompromised patients. We describe an invasive patient with immunocompetent who present progressive ocular dysfunctions. A 66-year-old woman no history of immune dysfunction was referred to our hospital orbital complications. Computed tomography (CT) scan magnetic resonance imaging (MRI) showed mass lesion extending from the left apex sinus. Inflammatory diseases were not suspected by laboratory findings,...
Objective: The effects of treatment methods for ruptured aneurysms on the incidence vasospasm and normal pressure hydrocephalus (NPH) following subarachnoid hemorrhage (SAH) are controversial. We retrospectively examined Nagasaki SAH registry data, complication rates symptomatic NPH were analyzed based methods.
Background and Purpose: Aneurysmal rebleeding is a major cause of death morbidity in patients with aneurysmal subarachnoid hemorrhage (SAH). Recognizing the predictors might help to identify who will benefit from acute management. This study was performed investigate their impact on clinical outcomes preoperative, intraoperative, postoperative periods. Methods: The incidence rebleeding, demographic data, data 4933 SAH beginning year 2000 were retrospectively analyzed Nagasaki Registry Study....
We evaluate our surgical approach for the treatment of anterior communicating artery (AcomA) aneurysms. Between March 2004 and August 2012, 56 cases with AcomA aneurysms were treated by clipping at institute retrospectively reviewed about approaches postoperative complications. Of patients aneurysms, eight through interhemispheric approach, 48 pterional (PA). In 38 clipped PA, open A2 fork side chosen, 10 PA from closed side. cases, four had to dominant A1 (“reversed-torsion AcomA”), dorsal...
前大脳動脈近位部 (A1) 動脈瘤は通常穿通枝分岐部より発生し, 開頭脳動脈瘤クリッピング術による治療難度の比較的高い病変である. 今回筆者が経験した6例について後方視的検討を加えた. 後方発育の割合が比較的多いこの部位の動脈瘤においては, 通常の脳血管撮影では動脈瘤が親血管に隠れ描出困難である場合が多く, その局在診断においては三次元回転血管造影法の有用性が示唆された. 開頭脳動脈瘤クリッピング術においては穿通枝の確実な同定と注意深いクリッピングにより穿通枝梗塞の合併回避が可能と考えられたが, 手術顕微鏡による形態学的評価のみでなく, 血流のリアルタイムイメージングであるインドシアニングリーン (ICG) を用いた術中蛍光血管撮影 (ICGA) が穿通枝温存および脳動脈瘤根治性の評価において本部位から発生した脳動脈瘤手術においては必須の検査であると考えられた. また, 術後のbrain shiftを念頭に置き, 動脈瘤頚部長に合ったブレード長のクリップの使用や有窓クリップの使用などが重要であることが示唆された.
症例は29歳男性である．2008年に肺サルコイドーシスを指摘された．2010年10月下旬に38°C台の発熱，頭痛が出現した．11月より膿疱性乾癬の診断で皮膚科へ入院したが，発熱，頭痛が改善せず当科に転科した．頭部MRIで脳底部を中心に微小造影結節をみとめた．脳脊髄液検査で細胞数，蛋白が増加し，糖は7 mg/dlと著明な低値を示した．抗結核薬，ステロイドパルス療法をおこなったが臨床症状，検査値ともに改善しなかった．髄膜生検で髄膜播種性サルコイドーシスと診断した．プレドニゾロン60 mg/日を開始し，症状は著明に改善した．髄膜播種性サルコイドーシスでも髄液糖が著明に低下する可能性に留意すべきである．
Ischemic stroke associated with intracranial aneurysm is rare but potentially happens because of emboli originating from sac or aneurysmal thrombosis extension to the parent artery. We describe two patients who present subarachnoid hemorrhage (SAH) soon after ischemic stroke. Case 1. A 51-year-old woman a history multiple endovascular therapy for ruptured basilar top presented double vision. Magnetic resonance imaging (MRI) revealed infarcts in right thalamus and left occipital cortex. Four...
