The effect of neutrophil/lymphocyte ratio and tomography measurements at the time of diagnosis in predicting aneurysm rupture in patients with abdominal aortic aneurysms

Results: The mean follow-up was 2.5 (range, 2 to 4) years. The mean abdominal aortic size, neutrophil percentage, and NLR were significantly higher in the ruptured group, while the mean lymphocyte ratio was significantly lower in the ruptured group. There was a significant correlation between the abdominal aortic size and NLR. Using the receiver operating characteristics, the NLR was found to be more sensitive and specific than the abdominal aortic diameter in predicting rupture.

Conclusion: Our study results indicate that abdominal aortic diameter, smoking, and hypertension are the risk factors for rupture of AAAs. In addition to classical risk factors, NLR is a novel and simple predictor of aortic rupture.
