Objective: The Neutrophil-to-Lymphocyte-Ratio (NLR) has already been investigated as an independent predictive marker for clinical outcome in vascular diseases. This study aimed to investigate the peri-interventional behavior of NLR in patients with ruptured and unruptured intracranial aneurysms (IAs).

Methods: 117 patients with IAs, who were treated in our department and had available completed data, were retrospectively identified during a ten-year period. Routine laboratory parameters, including neutrophil and lymphocytes, were measured at baseline and follow-up (FUP) visits.

Results: The baseline NLR showed significant differences between patients with ruptured and unruptured IAs [6.3 (IQR 4.2-9.0) vs. 1.8 (IQR 1.6-2.3), p<0.001]. In patients with ruptured IAs, baseline NLR significantly decreased during the FUP visits, while in unruptured IAs, the NLR remained low. In patients with ruptured IAs, higher baseline NLR values could be observed in patients with fatal outcome, in comparison to surviving patients [8.0 (IQR 5.2 -9.1) vs. 5.4 (IQR 4.0-9.0); p=0.220]. In patients with poor functional outcome, defined as modified Rankin Score (mRS) 33, NLR was significantly higher before treatment [7.2 (IQR 4.7-9.6) vs. 5.3 (IQR 3.5-8.1); p=0.047], but also at day 10 [5.4 (IQR 3.9-6.8) vs. 4.2 (IQR 3.3-5.9); p=0.025] and one month after treatment [3.5 (IQR 2.5-5.8) vs. 2.3 (IQR 1.7-2.9); p=0.001].

Conclusion: The peri-interventional NLR was significantly different between patients with ruptured and unruptured IAs. In patients with ruptured IAs, elevated baseline NLR levels was associated with poor postoperative functional outcomes and decreased postoperatively, implying the potential prognostic importance of NLR in patients with IAs.
