特発性大動脈破裂に対する胸部ステントグラフト内挿術

Thoracic Endovascular Aortic Repair for Idiopathic Aortic Rupture

特発性大動脈破裂はまれな疾患1）であるが，緊急に治療をしなければ致死的な状態となる．われわれは，背部痛を主訴に来院し，術前ショック状態に陥った特発性大動脈破裂に対して胸部ステントグラフト内挿術（TEVAR）を行い，良好な結果を得た2例を経験した．若干の考察を加え報告する．

Idiopathic aortic rupture is a rare but often fatal condition that requires urgent attention and repair. I have performed thoracic endovascular aortic repair （TEVAR） in two cases of idiopathic aortic rupture and have achieved positive results. It can be difficult to identify the site of rupture in these cases. Therefore, it is necessary to lengthen treatment and to determine the potential for spinal cord ischemia and associated paralysis of the lower extremities. Given its association with a favorable postoperative recovery, TEVAR can be considered as a minimally-invasive option that can be used early to treat this condition, including those associated with hemodynamic instability and in patients who are at high risk for complications.
