Current status of indirect decompression with lateral lumbar interbody fusion
The adoption of lumbar fusion techniques, particularly lateral lumbar interbody fusion (LLIF), has significantly evolved the management of degenerative lumbar spinal conditions. LLIF, introduced as a minimally invasive surgical procedure, offers the advantage of indirect neural decompression and robust bone fusion using large interbody cages, reducing complications such as cage subsidence and nerve injuries. Systematic reviews have indicated that LLIF was effective for foraminal decompression, although evidence regarding its effectiveness for spinal canal and lateral recess decompression remains limited. Comparisons between indirect decompression techniques like LLIF and direct methods (posterior lumbar interbody fusion and transforaminal lumbar interbody fusion) have revealed that while indirect approaches generally promoted lower surgical times and blood loss, outcomes related to pain, disability, and complications were comparable. Indirect decompression with LLIF should be approached cautiously or avoided in patients with severe stenosis or preoperative neurological impairments due to the increased risk for postoperative complications. Furthermore, meticulous surgical planning and advanced imaging techniques are essential for mitigating risks such as vascular, bowel, and ureteral injuries. Continued advancements in surgical instrumentation and navigation technologies are expected to further refine the utility of LLIF in treating complex spinal pathologies, offering a promising minimally invasive option for achieving effective spinal stabilization and decompression.departmental bulletin pape
Midterm results of aortic arch replacement with frozen elephant trunk for chronic dissecting aortic aneurysm involving the aortic arch
We performed total aortic arch replacement (TAR) with a frozen elephant trunk (FET) for chronic dissecting aortic aneurysm (DAA) involving the aortic arch as the initial surgery and carefully observed these aortic findings with periodic computed tomography (CT) follow-up. Additional surgical interventions were considered when aortic events were observed. Midterm outcomes were evaluated to clarify the feasibility of this strategy. Thirty-seven patients underwent TAR with FET between 2014 and 2020. The median follow-up period was 48.6 months. There was 1 case of operative mortality (2.7%) and 11 late deaths, including five aortic-related deaths. Aortic events occurred in 26 patients (72.2%), including 14 cases of stent-induced new entry (SINE), eight cases of aneurysmal enlargement, two cases of graft infection, and one each of additional aortic dissection and aortic root enlargement. Thirty-one procedures were performed, including 14 open surgeries, 16 thoracic endovascular aortic repairs (TEVAR), and 1 endovascular aortic repair (EVAR) with coil embolization. The freedom rate from aortic events was 36.9% at three years and 22.8% at five years. The distal aortic arch showed significant shrinking (slope, –1.96; P40.5 mm) and aneurysm enlargement (>40.2 mm). The present study showed acceptable early outcomes but frequent aortic events during follow-up. Cautious periodic CT is mandatory to perform additional reinterventions at the proper time, and scheduled surgical intervention, including TEVAR, is essential for cases with enlarged middle descending aortas.departmental bulletin pape

AI音声認識技術を活用した講義収録システム導入後の成果 : 名古屋大学法科大学院における取り組み
2005年10月より名古屋大学法科大学院では講義を繰り返し視聴できる環境を提供している。2022年4月からはAI音声認識技術を活用した講義収録システムDaAlps(ダルプス)for Educaion(講義収録・音声解析連携システム。以下DaAlpsと記載)を導入し、収録した講義の動画を「AI」解析することで動画と文字情報を提供している。学生は文字情報からよくわからなかった講義箇所、もう一度復習したいと考えた箇所の映像をピンポイントで再生できる。DaAlpsの機能と利用状況については2023年度大学ICT推進協議会年次大会で報告した。本稿ではDaAlpsの視聴統計データ閲覧機能を示し、学生の視聴結果から学修における問題点を予想し改善に繋げる方法を提案する。さらに学生への利用に関するアンケート結果からDaAlps導入により学生が法学知識の理解を深める上で効果のあることが明らかになったことを示す。departmental bulletin pape
