- Background: Intraluminal thrombus (ILT) is present in most abdominal aortic aneurysms (AAAs), although its role in AAA progression is controversial. Methods: A literature search was performed to identify studies that investigated the association between ILT volume and AAA rupture. A study assessment tool was developed to assess the methodologic quality of included studies. A meta-analysis was conducted using an inverse variance-weighted random-effects model to compare the ILT volume in ruptured and asymptomatic intact AAAs. Leave-one-out sensitivity analyses were conducted to assess the robustness of the findings. A subanalysis was performed including studies in which patients with asymptomatic intact and ruptured AAAs were matched for aortic diameter. Interstudy heterogeneity was assessed using the I2 statistic. Results: Eight studies involving 672 patients were included in this systematic review. Meta-analysis of all studies found a greater ILT volume in patients with ruptured AAAs than in patients with asymptomatic intact AAAs (standardized mean difference, 0.56; 95% confidence interval, 0.17-0.96; P =.005; I2 = 79.8%). Sensitivity analyses suggested that the findings were robust; however, aortic diameter was significantly larger in ruptured than in asymptomatic intact AAAs (mean ± standard deviation, 78 ± 18 and 64 ± 15 mm, respectively; P <.001). In the subanalysis of studies that matched for diameter, no significant difference in ILT volume between groups was found (standardized mean difference, 0.03; 95% confidence interval, −0.27 to 0.33; P =.824; I2 = 0%). Conclusions: This meta-analysis suggests that ILT volume is greater in patients with ruptured AAAs than in patients with asymptomatic intact AAAs, although this is most likely due to the larger diameter of ruptured AAAs.
