Outline of Final Research Achievements

Endovascular aneurysm repair (EVAR) has become a viable alternative to conventional surgical open repair owing to its perioperative survival benefit; however, EVAR is associated with a unique complication called endoleak (EL), which continues to perfuse and pressurize the aneurysm sac and cause aneurysm enlargement and rupture.
Type I and type III endoleak were more detectable with MR angiography and streamline analysis with 4D Flow within the aneurysm. A comprehensive analysis of concurrent multiple T2EL vessels using 4D-flow MRI may enable prediction of the sac expansion after EVAR by larger amplitude of the flow velocity in the branch arteries.

Academic Significance and Societal Importance of the Research Achievements

高齢化が加速する本邦にあって、低侵襲治療であるEVARは今後も増加してゆく可能性が高いが、そのトレンドにあって、瘤破裂につながりかねないEVAR後のエンドリークの問題解決は焦眉の急と考えられる。本研究では、侵襲性の低い造影MR angiographyや4D Flow MRIといった新しい方法で従来法よりも高い感度でエンドリークを診断できる可能性が示された。流れという従来あまり利用されてこなかった学術的にも新規な方法論によって、腹部大動脈瘤の自然史解明につながる知見が得られた意義は大きい。
