胸部ステントグラフト内挿術後遠隔期に認めたタイプⅢbエンドリークの1例

Delayed TypeⅢb Endoleak After Thoracic Endovascular Aortic Repair for Thoracic Aortic Aneurysm：Report of a Case

はじめに　ステントグラフトの進歩により胸部ステントグラフト内挿術（TEVAR）が選択される疾患は拡がりつつあるが，これに伴い特有の合併症の報告も増えつつある．TEVAR施行後遠隔期にタイプⅢbエンドリークを認めた症例を経験したので報告する．

An 85-year-old woman underwent aortic arch replacement and thoracic endovascular aortic repair （TEVAR） 5 years ago. She suffered from chest and back pain. Computed tomography （CT） demonstrated enlargement of the aortic aneurysm by a typeⅢb endoleak. TEVAR was performed to close a typeⅢb endoleak with a relining technique uneventfully. Intraoperative completion aortography and postoperative CT confirmed the disappearance of a typeⅢb endoleak. She was discharged 27 days after the treatment.
