An innovative exclusion technique for ductus arteriosus with a novel stent graft

Use of stent-grafts for the ductus arteriosus and its related lesions

Five cases of ductal lesions with various anatomies have been successfully treated by thoracic endovascular aortic replacement in recent years; 4 using mainly fenestrated stent-grafts, and one using a non-fenestrated stent-graft. Considering the invasive nature of open surgery and the anatomical limitations of the catheter technique for occluding a patent ductus in many adult cases, thoracic endovascular aortic replacement should be the first option because of its broad applicability for ductal lesions.

Thoracic endovascular aortic repair for patent ductus arteriosus in an elderly patient with congestive heart failure

In elderly patients, open surgery for patent ductus arteriosus (PDA) is more difficult than that in children and often requires a cardiopulmonary bypass. We report the case of a 67-year-old patient with a PDA that was successfully treated with thoracic endovascular aortic repair (TEVAR). The patient was diagnosed with congestive heart failure (ejection fraction, 36 %) and PDA (9.7 mm in diameter). TEVAR was successfully performed to exclude the PDA. After TEVAR, the patient's heart failure was well controlled by diuretics. TEVAR may be a good alternative to open surgery.
