A 72-year-old woman underwent thoracic endovascular aortic repair (TEVAR) for an aortic arch aneurysm at a previous hospital. During follow-up, although the aneurysm was found to have become bigger, no further treatments were given, except for conservative follow-up. The patient sought a second opinion and thus visited our hospital. Enhanced computed tomography (CT) revealed a type I endoleak that required repair. Total arch replacement with removal of the partial stent-graft system was performed under deep hypothermic circulatory arrest. The patient made a steady progress postoperatively and was discharged without any complications. Endovascular repair is minimally invasive and frequently used in various medical facilities but carries a considerably high risk of reintervention. Treatment strategies for aortic aneurysm, including open surgery, should be carefully chosen.

A 11-year-old boy was admitted to our hospital with a diagnosis of the progressive residual coarctation of the aorta, severe left ventricular hypertrophy and dilatation of the ascending aorta. He had previously undergone 3 operations for coarctation of the aorta. We performed ascending-to-descending aortic bypass through a median sternotomy for residual coarctation of the aorta. Partial cardiopulmonary bypass (CPB) was established via the right femoral artery and right atrium. A cephalad retraction of the heart with a heart positioner and a longitudinal pericardial incision over the descending aorta allowed excellent exposure of the aorta through the posterior pericardium. The graft was anastomosed to the ascending aorta and descending aorta. The graft was brought around the right lateral aspect of the right atrium and through to the anterior aspect of right pulmonary veins and inferior vena cava. The bypass graft size was 14 mm in diameter. The CPB time was 134 min, and operation time was 232 min. The postoperative course was uneventful, and he did not suffer from paraplegia. His blood pressure postoperatively normalized without medication. He was discharged 20 days after surgery. The ascending-descending aortic bypass through a posterior pericardium approach is a safe and effective option for relieving residual coarctation and improving hypertension, for patients who have complex coarctation requiring surgical correction. However, because of his young age (II) it is necessary to follow him up carefully.

A 63-year-old man had undergone patch repair of a chronic dissecting thoracoabdominal aortic aneurysm 8 years previously. Postoperative course was uneventful during 8 years after the first operation. However follow-up CT scan 8 years after demonstrated pseudoaneurysm of thoracoabdominal aorta at the anastomotic side. Reoperation for pseudoaneurysm was performed through left thoracotomy under partial cardiopulmonary bypass. Pseudoaneurysm was revealed at the proximal anastomotic side. Graft replacement for thoracoabdominal aorta and reconstruction of two pairs of intercostal arteries and the celiac artery was performed under SEP and MEP monitoring. His postoperative course was uneventful. He was discharged from our hospital 12 days after surgery. Follow-up CT scan demonstrates no recurrence of pseudoaneurysm for 1 year after surgery.
