Thoracic endograft positioning and carotid-subclavian bypass grafting in a patient with a saccular aneurysm at the aortic arch.
A 75-year-old man was referred to our hospital because of sudden thoracic pain. A saccular aneurysm of the aortic arch extending on the anterior surface of the aortic arch was found on computed tomographic arteriography. The patient was hemodynamically stable and he was programmed for a staged surgical and endovascular approach (hybrid approach). As a first stage and in order to prevent major cardiac complications due to the overstenting of the left subclavian artery (LSA) with the occlusion of the aortocoronary bypass, the patient underwent a polytetrafluoroethylene bypass graft (GORE-TEX, W.L. Gore & Associates, Flagstaff, AZ) between the LSA and the left carotid artery. Intraoperative arteriography revealed a good patency of the left carotid-subclavian bypass and of the left internal mammary bypass on the left anterior descending artery. As a second stage the endovascular procedure was accomplished 5 days later in the operating room. A Gore TAG stent graft (W.L. Gore & Associates) was deployed in the aortic arch 20 mm proximally to the aneurysmatic segment covering the ostium of the LSA. The postoperative course was uneventful and the patient was discharged on the fifth postoperative day in good general conditions. Hybrid procedures for treatment of aneurysms of the aortic arch or of the descending thoracic aorta are a promising alternative to open surgery especially in high-risk patients, with lower early morbidity and mortality rates. Long-term effectiveness remains to be fully elucidated.
