    症例は48歳女性で、前日からの頭痛を主訴とした。頭部CTでくも膜下出血を脳底槽からシルビウス裂に認め、やや左優位であった。脳血管撮影では右内頸動脈・左内頸動脈・左中大脳動脈・左前大脳動脈に多発脳動脈瘤を認めた。造影MRIによるvessel wall imagingで破裂瘤は右内頸動脈前壁動脈瘤の可能性が高いと判断し、同日開頭クリッピング術を行ったが、術中破裂所見は認めず動脈瘤を切除した。翌日に左側開頭クリッピング術を行い、左前大脳動脈瘤を破裂瘤と判断し、中内脳動脈瘤と左内頸動脈瘤もクリッピングした。初回手術7日後に脳血管撮影にて各動脈瘤の消失を確認し、遺残した高次脳機能障害のリハビリテーション目的に第76病日に転院した。切除した右内頸動脈瘤の病理所見では脳動脈瘤壁に炎症細胞の浸潤および毛細血管の増生を認め、造影された原因と考えられた。

    The use of an endoscope in exoscopic transcranial neurosurgery for skull-base lesions has not yet been investigated. Thus, this study aimed to investigate the advantages, disadvantages, and safety of "simultaneous temporary use of an endoscope during exoscopic surgery" (exo-endoscopic surgery (EES)). Consecutive exo-endoscopic surgeries performed by experienced neurosurgeons and assistants were analyzed. Surgical complications and time were compared with previous consecutive microsurgeries performed by the same surgeon. A questionnaire survey was conducted on 16 neurosurgeons with experience in both "temporary simultaneous use of endoscope during microscopic surgery" (micro-endoscopic surgery (MES)) and EES. EES was performed in 18 of 76 exoscopic surgeries, including tumor removal (n = 10), aneurysm clipping (n = 5), and others (n = 3). There were no significant differences in operative time, anesthesia time, or complications from microsurgery by the same operator. According to the questionnaire survey results, compared with MES, EES had a wider field of view due to its lack of an eyepiece, was easier when loading and unloading instruments into and out of the surgical field, and was more suitable for the simultaneous observation of two fields of view. Overall, 79.2% of surgeons indicated that EES may be better suited than MES to simultaneously observe two fields of view.

    BACKGROUND: Aneurysmal subarachnoid hemorrhage is a rare but important cause of maternal death during pregnancy. CASE DESCRIPTION: A 34-year-old primigravida (31 weeks of pregnancy) with acute headache but no neurological deficits or neck stiffness was prescribed medication and returned home. Four weeks later she presented with severe headache and consciousness disturbance. She was admitted to our hospital, where she fell into a deep coma. Brain CT and three-dimensional CT angiography showed subarachnoid hemorrhage and a 5-mm right internal carotid-posterior communicating artery aneurysm. Fetal heart rate was 60 beats per minute. Emergent cesarean section and surgical clipping were performed. Intraoperative examination revealed that the aneurysm originated at the right posterior communicating artery. There were no postoperative neurological focal deficits. On postoperative day 13 she developed delayed cerebral ischemia of the right temporo-parieto-occipital lobe. She was discharged home 36 days after surgery with left hemianopsia. The infant was free of complications and was discharged at age 17 days. CONCLUSIONS: A pregnant woman with severe headache should undergo brain CT or magnetic resonance imaging to rule out subarachnoid hemorrhage.

    BACKGROUND: The exoscope has been reported as a novel neurosurgical instrumentation in clinical practice. OBJECTIVE: To investigate the possibility that ORBEYE (OE), a novel instrument that excludes eyepiece lenses and allows for microsurgery by observation of the 4K3D monitor, could replace microscopes. METHODS: We report 22 clinical cases by 5 experienced neurosurgeons and the comparative results of training 10 residents. An observation study with questionnaire survey was conducted on usability. Twelve items including image quality, eyestrain, and function of the arm were evaluated. RESULTS: The following 22 clinical procedures were conducted: surgery for intracranial hemorrhage (n = 2) and brain tumor (n = 8), laminectomy (n = 3), aneurysm clipping (n = 3), vascular anastomosis (n = 2), carotid endarterectomy (n = 2), and nerve decompression (n = 1). No complications were observed. The fluorescent study, including indocyanine-green and 5-aminolevunic acid, allowed for clear depiction on the 4K monitor. The surgeon could operate in a comfortable posture. Similar to the microscope, it was possible to change the optical and viewing axes with the OE, but the OE was switched to the microscope or endoscope in hematoma removal and pituitary surgery. Residents judged that eyestrain was strong (P = .0096). Experienced neurosurgeons acting as assistants judged that the scope arm's range of movement was narrow (P = .0204). Sixty percent of residents judged that the OE was superior to the microscope. CONCLUSION: Although based on limited experience, it was not possible to substitute the microscope with the OE in all operations; however, the OE surpasses the microscope in terms of ergonomic features.
