Outline of Final Research Achievements	Throughout the entire period of this research grant, research activities were greatly restricted due to the spread of coronavirus infection that occurred after the research funding was obtained, causing major hindrances to the implementation of the research plan. Although it has recently been classified as a Class 5 infectious disease, its impact is strong throughout the research institution, and progress in accumulating cases has been slow, making it almost impossible to carry out personnel exchanges for program creation. In such circumstances, we had several online meetings with Kobe University, and came up with the idea of programing based on measuring blood pressure at multiple sites within the aortic aneurysm and creating a precise simulation program based on that data, but we were unable to realize it.

Academic Significance and Societal Importance of the Research Achievements	前述したとおり、本研究助成の全期間にわたって、研究費獲得後に発生したコロナウイルス感染拡大によって、研究活動が大きく制限され、研究計画遂行に大きな支障が生じた。数回にわたりオンラインミーティングを開催する事はでき、前述したオンラインミーティングからプログラムソフト作成のきっかけをつかむ事が出来たものの、それを実践に移すための症例データ蓄積をすることができなかった。とはいえ、今後新規の科研費獲得ができた際には、その知見をもとに研究をより迅速に進めるための礎として利用できると考えている。
