Introduction : Prevention of embolic stroke is the key issue to perform aortic arch replacement in patients with a shaggy aorta. The aim of this study is to report the utility of the isolation technique for total arch replacement in patients with a shaggy aorta. Methods : Clinical results of seven patients (71.7 years old, all men) with a shaggy aorta who underwent total arch replacement between January 2017 and November 2018 were retrospectively reviewed. The operative indications were a distal arch or proximal descending aortic aneurysm in 6 patients and a thrombus inside brachiocephalic artery in one. A cerebral perfusion was established by inserting a cannula directly into all supra-aortic branches before starting systemic perfusion. Result : Utilizing the isolation technique with clamping of all branches in 4 patients and the functional isolation technique with clamping of two branches in 3, total arch replacement was performed in all patients (operation time : 513 min, selective cerebral perfusion time : 162 min). No operative death was observed and no newly developed stroke was encountered. Conclusion : The isolation technique is a useful method to prevent stroke during total arch replacement in patients with a shaggy aorta.

<p>A 76-year-old woman required aortic valve replacement due to severe aortic stenosis. She had a huge thyroid cancer, which invaded the innominate and left internal jugular veins. We planned a two-stage operation : the first involved aortic valve replacement ; and the second involved operation of the thyroid cancer. To avoid median sternotomy, we adopted the right parasternal approach. A 7-cm right parasternal skin incision was made. The third and fourth costal cartilages were cut and bent into the right thoracic cavity, without removal of the ribs. The postoperative course was uneventful, and second operation was performed via the median sternotomy approach on postoperative day 53. The right parasternal approach can be used as an alternative when sternotomy is unsuitable in cases of aortic valve replacement.</p>
