《Circulation: Cardiovascular Imaging》:Increased Venous Volumes in Response to Catheter-Based Intervention for Acute PE: Lessons From the OPTALYSE PE Trial (OPTALYSE-3D)
为了便于比较,将不同剂量组合并为低剂量组(n=28)和高剂量组(n=25)。两组之间小血管体积的净增加量(0.76 [0.02–2.7] vs 0.36 [?0.4 to 1.55],P=0.24)、中等血管体积(1.4 [0.03–2.2] vs 1.6 [0.36–2.7],P=0.83)或大血管体积(0.5 [?0.1 to 1.0] vs 0.6 [0.1–1.3],P=0.68)没有差异。小血管体积(0.28 [?0.43 to 2.5] vs ?0.64 [?1.8 to 0.6],P=0.06)和大血管体积(?0.1 [?1.1 to 0.9] vs ?0.9 [?0.4 to 1.6],P=0.08)略有下降(但无统计学意义)。中等动脉体积的变化(?0.1 [?1.1 to 0.9] vs ?0.02 [?2.1 to 2.7],P=0.70)在两组间相当。
