BACKGROUND: Information on the growth rate of the diameter of the residual dissected supra-aortic trunk after surgical repair of @entity1580 is limited. METHODS: We retrospectively reviewed 95 consecutive postsurgical @entity1 with @entity1580 (acute, 91; chronic, 4) between 2005 and 2016 who were followed up with computed tomography. The diameter of the residual dissected supra-aortic trunk was measured by axial images and multiplanar reformatting, and the growth rate was calculated. RESULTS: The mean age was 67.2     12.8  years (range, 34-89  years). Forty-one brachiocephalic arteries (43%), 14 left common carotid arteries (15%), and 7 left subclavian arteries (10%) exhibited residual dissection. The diameter of the residual dissected branch with a patent false lumen (FL) gradually increased over time, whereas that with a thrombosed FL decreased and reached a plateau. The growth rate of brachiocephalic, left common carotid, and left subclavian arteries with a patent FL was 1.3     1.2, 0.8     0.3, and 0.6     0.4  mm/y, respectively. One @entity1 required surgical intervention for dilation of the brachiocephalic artery 8  years postoperatively. Multivariate analysis showed that male sex was an independent risk factor for a patent FL in the brachiocephalic artery (P  = .0431; odds ratio, 2.04). CONCLUSIONS: A residual dissected supra-aortic trunk with a thrombosed FL seems to be a benign condition. However, long-term follow-up is necessary for @entity1 with a patent FL of residual dissected supra-aortic trunk, which might occasionally require surgical intervention.
