Objective:To investigate the changes in serum levels of interleukin-1β (IL-1β) and hypoxia-inducible factor-2α (HIF-2α) in patients with intracranial aneurysms before and after surgery, and their relationship with clinical prognosis.Methods:A prospective research method was used, a total of 120 patients with intracranial aneurysms who underwent endovascular embolization treatment in Xi'an NO.9 Hospital from December 2019 to December 2022 were selected as the study subjects. According to the prognosis after one-year follow-up, they were divided into poor prognosis group and good prognosis group. The general data of the two groups and the changes of serum IL-1β and HIF-2α levels before and after surgery were compared and analyzed. The changes of serum IL-1β and HIF-2α before and after surgery in patients with intracranial aneurysms and their relationship with the prognosis of patients were analyzed.Results:Among the 120 patients, 98 (81.67%) had a good prognosis and 22 (18.33%) had a poor prognosis. The proportion of large and wide necked aneurysms in the poor prognosis group was higher than that in the good prognosis group: 40.91% (9/22) vs. 10.20% (10/98), 45.45% (10/22) vs. 20.41%(20/98), with statistical significant differences ( P<0.05). On postoperative day 7, the serum levels of IL-1 β and HIF-2 α in the poor prognosis group were higher than those in the good prognosis group: (62.58 ± 6.12) ng/L vs. (56.95 ± 5.33) ng/L, (101.62 ± 10.55) ng/L vs. (92.70 ± 7.82) ng/L, with statistical significant differences ( P<0.05). Multivariate Logistic regression analysis showed that the size of aneurysms, including giant aneurysms, wide necked aneurysms, and high levels of serum IL-1β and HIF-2α 7 d after surgery, were independent risk factors for clinical prognosis in patients with intracranial aneurysms ( P<0.05). The working characteristic curve of the subjects was drawn, and the results showed that serum IL-1β and HIF-2α had certain predictive value for the clinical prognosis of intracranial aneurysm patients 7 d after surgery, but their sensitivity was relatively low. The parallel experiment method was used to jointly predict the samples. The results showed that the area under the curve for predicting the clinical prognosis of intracranial aneurysm patients with serum IL-1β and HIF-2α at 7 d after surgery was 0.867, with sensitivity and specificity of 86.40% and 74.50%, respectively, indicating high predictive value. Conclusions:The levels of serum IL-1β and HIF-2α are significantly elevated in patients with intracranial aneurysms after surgery, and are closely related to their clinical prognosis, which can help predict the clinical prognosis of intracranial aneurysm patients.

Objective:To preliminarily investigate the safety and efficacy of Pipeline embolization device (PED) in the treatment of unruptured intracranial vertebral artery dissecting aneurysm (VADA).Methods:Patients with unruptured intracranial VADA received PED treatment in the Department of Neurosurgery, Xi'an Ninth Hospital from December 2015 to September 2023 were included retrospectively. Their demographic data, vascular risk factors, clinical symptoms, preoperative modified Rankin Scale (mRS) scores, imaging data, and treatment regime were collected. The O'Kelly-Marotta (OKM) grading scale was used to evaluate the occlusion of aneurysms.Results:A total of 18 patients with unruptured intracranial VADA were enrolled, including 12 males (66.7%), aged 37-67 years. All patients successfully completed PED implantation without any periprocedural complications. Six patients (33.3%) were treated with coil-assisted embolization, and 12 (66.7%) were treated with PED implantation alone. Digital subtraction angiography (DSA) showed contrast retention in aneurysm lumen in 10 patients (55.6%) immediately after surgery. Clinical follow-up was performed in 18 patients, of which the mRS score was 0 in 12 patients (66.7%) and the mRS score was 1 in 6 patients (33.3%). Fifteen patients (88.3%) received DSA follow-up, including 12 (80.0%) with OKM grade D and 3 (20.0%) with grade C, and the posterior inferior cerebellar arteries had smooth blood flow.Conclusion:PED is safe and effective in the treatment of unruptured intracranial VADA.
