Spontaneous hematoma resolution is an important determinant of functional recovery, but the biological mechanisms underlying this process remain poorly understood. Coagulopathy, common in ASDH, may influence hematoma dynamics, but its causal role remains uncertain.  \nMethods: We conducted a two-sample Mendelian randomization (MR) study to investigate the causal effects of coagulation traits on hematoma resolution. Genetic instruments for fibrinogen isoforms, coagulation factors VIII, XI, V, VII, natural anticoagulants, and platelet traits were obtained from large genome-wide association studies. Due to the absence of ASDH-specific GWAS data, we used genetic susceptibility to intracerebral hemorrhage (ICH) and poststroke functional outcome as indirect proxies for hematoma persistence and clearance. We acknowledge that these proxies cannot fully capture the unique pathophysiology of ASDH, but they represent pragmatic, biologically relevant surrogates. Causal estimates were obtained using inversevariance weighted MR with robust sensitivity analyses.  \nResults: Genetically higher fibrinogen γ' levels were associated with increased odds of hematoma resolution (OR 1.25, 95% CI 1.10–1.42). Higher factor VIII and XI levels were associated with reduced odds of Resolution (OR 0.82, 95% CI 0.72–0.94; OR 0.88, 95% CI 0.78–1.00). Secondary analyses using poststroke functional outcome yielded similar patterns but did not reach statistical significance (OR ~1.10, p = 0.15) .  \nConclusions: Our findings provide genetic evidence suggesting coagulation pathways, particularly fibrinogen γ' and factors VIII and XI, may influence hematoma resolution in ASDH. However, due to the indirect nature of the proxies used, these results should be considered hypothesis-generating and require further validation in ASDH-specific cohorts.  \n1 | Introduction  \nAcute subdural hematoma (ASDH) represents one of the most devastating complications of traumatic brain injury, with persistently high rates of mortality and disability worldwide [1–3] . Although surgical evacuation remains the mainstay of treatment, spontaneous hematoma resolution is increasingly recognized as an important determinant of functional recovery  \nin carefully selected patients [4–6] . However, the biological mechanisms that underlie such spontaneous absorption remain poorly understood, limiting our ability to stratify patients and to optimize both surgical and conservative management [5, 6] . Coagulopathy, either pre-existing or trauma-induced, is frequently observed in ASDH and has been associated with hematoma expansion, impaired clearance, and poor outcome [7–9] . Yet, conventional observational studies cannot fully disentangle  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2026 The Author(s).
