[Open Aortic Arch Surgery for Type Ⅰ Endoleak after Thoracic Endovascular Aortic Repair Using Fenestrated Stent Graft;Report of a Case].

Thoracic endovascular aortic repair (TEVAR) has become a major procedure for thoracic aortic aneurysm and its indication is expanding. On the other hand, TEVAR specific complication is rather critical and its treatment is of increasing interest. Especially, open repair after TEVAR is sometimes demanding and case based strategy is mandatory. We experienced a case of open repair for aneurysm infection and endoleak after fenestrated TEVAR in 76-year-old man. He underwent initial aneurysmal repair using fenestrated graft 2 years ago. Five months later, debridment of infected tissue was performed because of aneurysmal infection. Type Ⅰ endoleak appeared after the surgery and expansion of the aneurysm made us decide extensive open repair. The operation was done under hypothermic circulatory arrest and selective cerebral perfusion. Partial removal of stent-graft and insertion of the open stent-graft, replacement of ascending aorta and reconstruction of neck vessels were done. Postoperative course was smooth. Open repair after TEVAR is often demanding. Sophisticated strategy for each case has to be planned.
