Table 2 Main study data

From: Aortic remodelling and false lumen changes after the frozen elephant trunk technique using the thoraflex hybrid stented graft for aortic dissection

  Pre-operative Early post-operative P-value
Ratio with total aortic lumen in both groups    
True aortic lumen 0.31 (0.12–0.86) 0.4 (0.19–0.88) 0.042*
False aortic lumen 0.66 (0.13–0.84) 0.54 (0.12–0.78) 0.02*
  Acute (n = 8) Chronic (n = 14) P-value
Association between patients’ presentation and true lumen to total aortic lumen ratio    
Pre-operative ratio between true lumen and total aortic lumen 0.37 (0.12–0.86) 0.27 (0.14–0.8) 0.25
Post-operative ratio between true lumen and total aortic lumen 0.55 (0.35–0.85) 0.27 (0.19–0.88) 0.009*
Change in the ratio before and after operation (post-operative ratio minus pre-operative ratio) 0.11 (− 0.08–0.85) 0.03 (− 0.14–0.21) 0.26
Association between patients’ presentation and false lumen to total aortic lumen ratio    
Pre-operative ratio between false lumen and total aortic lumen 0.63 (0.13–0.8) 0.68 (0.2–0.84) 0.5
Post-operative ratio between false lumen and total aortic lumen 0.45 (0.15–0.65) 0.63 (0.12–0.78) 0.005*
Change in the ratio before and after operation (post-operative ratio minus pre-operative ratio)  − 0.11 (− 0.51–0.08)  − 0.04 (− 0.21–0.14) 0.36
