PURPOSE: To evaluate the clinical efficacy of a curved @entity5648 stent-graft for repair of @entity2334 . METHODS: The Matsui-Kitamura stent-graft (MKSG), composed of a self-expanding @entity5648 stent and polyester fabric, was shaped to match the aortic curvature of 11 @entity1 (6 @entity1 ; mean age 72.6 years, range 33-90) with 6 true and 5 false @entity439 of the distal arch or proximal descending aorta. The delivery system was an 18 or 20-F J-shaped sheath combined with a preloader-type introducer. The original mean proximal neck length was 16.4 mm, but 4 @entity1 received an axilloaxillary bypass to lengthen the neck. Although the mean corrected proximal neck length was 21.9 mm (overall), 5 cases still had proximal necks <15 mm long. RESULTS: All curved MKSGs were successfully deployed in the correct position and fitted to the curvature of the aortic arch, achieving complete @entity439 in 8 (73%) cases. The other 3 repairs displayed @entity1070 ; 1 received an additional MKSG, but the other 2 are being observed. Thirty-day mortality was 0%. One @entity1 developed transient @entity177 requiring hemodialysis; no neurological complications were observed. CONCLUSIONS: Endovascular repair of @entity2334 using curved MKSGs appears to be feasible and clinically effective. A tighter fit of the device to the curvature of the aortic arch may exclude @entity439 despite a short proximal neck.
