Table 3 Comparison of draining vein, feeding artery and venous sac reduction rate between occluded and recanalized groups

From: Pulmonary arteriovenous malformation (PAVM) embolization: prediction of angiographically-confirmed recanalization according to PAVM Diameter changes on CT

  Occluded group (n = 40) Recanalized group (n = 10) p value
Draining vein reduction rate (%) 59.2 ± 9.3 (41.6–78.1) 5.4 ± 19.5 (-38.4-31.9) < 0.0001
Feeding artery reduction rate (%) 47.5 ± 10.6 (14.6–65.7) 11.3 ± 17.7 (-20.5-36.0) < 0.0001
Venous sac reduction rate (%) 62.6 ± 13.2 (41.3–79.5) 26.8 ± 14.2 (12.7–50.2) < 0.0001
CT follow-up (day) 850.2 ± 508.0 (147–1613) 965.4 ± 385.5 (486–1411) 0.442
