Figure 2. Periprocedural and follow-up changes of LAR width, LAR thickness, inner ostium and outer ostium diameter at 45/90° plane. Figure A & B shows LAR bulked in width and thickness significantly after combined procedure, while LAR subsided to its original width but remained thick during in the 3rd month follow-up.Figure C & D shows corresponding ostium diameter changes that outer ostium narrowed and expanded to its original size, while inner ostium stayed unchanged. Figure E & F showed the correlation of LAR width and thickness change at 45/90°after procedure. At both planes, width and thickness change were significantly correlated with each other, and the change in width were greater than thickness.
