術後に短絡が残存した動脈管開存に対して胸部ステントグラフトによる閉鎖を施行した1例

Thoracic Aortic Stent Graft for Patent Ductus Arteriosus with Residual Shunt after Surgical Repair；Report of a Case

はじめに　成人期の動脈管開存に対する治療法としては，外科的修復術や経カテーテル閉鎖術が確立されているが，近年，胸部ステントグラフト挿入術（TEVAR）も報告されている．われわれは，初回外科修復術後に短絡が残存した症例に対してTEVARによる閉鎖を施行したので報告する．

We report a case of a 75-year-old woman with residual shunt of patent ductus arteriosus after initial surgical repair. She was successfully treated by thoracic aortic stent graft and residual shunt disappeared. Re-surgical repair for residual shunt of patent ductus arteriosus is very invasive and challenging procedure. Also endo-vascular repair using coil or an occluding device can be problematic because of anatomical change due to initial surgical repair. Thoracic aortic stent graft, as a re-intervention procedure for patent ductus arteriosus, is simple, safe, and useful in elderly patients.
