Outline of Final Research Achievements

The current study examined the clinical significance of 18F-FDG-PET in patients with IMH in comparison to those with classic AD. During the median follow-up of 664 days, 37.3% of the patients had adverse aorta-related events. The higher total 18F-FDG uptake, defined as a sum of 18F-SUV uptake over the regions that had inflammatory pathology in the entire affected thoracic aorta, was associated with an increased risk of aorta-related event in patients with IMH even after multivariable adjustment, but not in those with AD. 18F-FDG-PET/CT might be useful for risk stratification in patients with IMH.

Academic Significance and Societal Importance of the Research Achievements

B型急性大動脈症候群(AAS)患者では、合併症を有さない場合は内科治療が施行されるが、慢性期に破裂や径の拡大等の大動脈関連事象をおこし予後不良である。近年、胸部ステントグラフト内挿術(TEVAR)を先制的に施行することによって予後の改善が見込まれることが報告されてきたが、どのような症例に対して施行するべきか、よく分かっていない。本研究では、PET-CT検査を用いることによって、B型AAS患者において、従来の画像所見とは異なる新たなリスクの層別化が可能であることが明らかになった。本研究の結果は、B型AAS患者の予後の改善や医療費の削減に寄与することが期待される。
