Abstract: Background: To analyze the value of four-dimensional computed tomography angiography (4D-CTA) combined with stromal cell-derived factor-1 (SDF-1) for differentiating ruptured intracranial aneurysms and assessing the risk of ruptures. Methods: Fifty patients with unruptured intracranial aneurysms and 50 patients with ruptured ones were included in non-rupture group 1 and rupture group 1, respectively. All patients underwent 4D-CTA and 3D-CTA, and the serum SDF-1 level was detected. Non-rupture group 1 was followed up for 12 months. On this basis, the patients with ruptured aneurysms were included in rupture group 2 and those without ruptured aneurysms were assigned to non-rupture group 2. Results: The AUC values of Wn, AR, L, SR, SDF-1 and their combination for the diagnosis of ruptured intracranial aneurysms were all >0.70, especially their combination. Wn, AR, L, and SR were higher in rupture group 2 than those in non-rupture group 2 (P<0.05). The level of SDF-1 in rupture group 2 [(142.48±11.23) μg/L] was higher than that in non-rupture group 2 [(128.03±10.28) μg/L] (P<0.05). Wn, AR, L, SR, and SDF-1 and their combination all had the AUC values of >0.70 for the prediction of ruptured intracranial aneurysms, especially their combination. The CT values of the internal carotid artery and middle cerebral artery and the CT value and noise of brain parenchyma in 4D-CTA were higher than those in 3D-CTA (P<0.05). Conclusions: 4D-CTA combined with SDF-1 can effectively differentiate ruptured intracranial aneurysms and predict the risk of ruptures. Keywords: four-dimensional computed tomography angiography, stromal cell-derived factor-1, rupture; intracranial aneurysm
