背景:

Kommerell diverticulum（KD）と異常鎖骨下動脈（ASA）は大動脈の血管異常です。

BACKGROUND: A Kommerell diverticulum (KD) and aberrant subclavian artery (ASA) are an aortic vascular anomaly.

症例報告:

右ASAと2つの無症候性胸部弛緩性大動脈瘤を合併した83歳男性のKDで、全弓置換術、凍結象幹術、段階的胸部血管内大動脈修復術で治療された1例を報告する。

CASE REPORT: We describe a case of a KD with a right ASA and two asymptomatic thoracic saccular aortic aneurysms in an 83-year-old man, which were treated with a total arch replacement, frozen elephant trunk technique, and staged thoracic endovascular aortic repair.

結論:

KDとASAの治療については、これまでにいくつかの報告がなされている。しかし，本症例のように80歳以上の患者に無症候性胸部弛緩性大動脈瘤とKDが共存していることは稀であると考えられる．

CONCLUSIONS: Some reports on the treatment of a KD and ASA have been reported thus far in the literature. However, it is considered rare to find two asymptomatic thoracic saccular aortic aneurysms coexisting with a KD in a patient over 80 years old, as was discovered in this patient.
