Abstract:Objective To analyze the effect of aspirin on epileptic seizures after acute large artery main trunk occlusive cerebral infarction.Methods A retrospective method was adopted. 384 patients diagnosed with acute large artery main trunk occlusive cerebral infarction and having their first seizure were selected from the Neurology Department of Lianyungang First People's Hospital from January 2019 to December 2022. Clinical data of the patients were collected. A 2-year follow-up was conducted through telephone or on-site follow-up. The patients were divided into the seizure group and the non-seizure group based on whether they had epileptic seizures. Multivariate general Logistic regression analysis was used to explore the influencing factors of epileptic seizures after acute large artery main trunk occlusive cerebral infarction.Results A total of 295 patients completed the final follow-up. Among them, 90 patients (accounting for 30.51%) had epileptic seizures. The NIHSS scores at admission, bleeding conversion rate, rate of infarction involving the parietal lobe, and temporal lobe rate in the seizure group were higher than those in the non-seizure group (P < 0.05), and the aspirin usage rate was lower than that in the non-seizure group (P < 0.05).. Multivariate general Logistic regression analysis showed that high NIHSS score at admission [O^R = 1.428 (95% CI: 1.241, 1.637) ], bleeding conversion [O^R = 3.976 (95% CI: 1.713, 9.123) ], infarction involving the parietal lobe [O^R = 2.125 (95% CI: 1.095, 4.120) ], and infarction involving the temporal lobe [O^R = 5.470 (95% CI: 2.608, 11.512) ] were all risk factors for epileptic seizures after acute large artery main trunk occlusive cerebral infarction (P < 0.05), and aspirin use [O^R = 0.182 (95% CI: 0.087, 0.401) ] was a protective factor for epileptic seizures after acute large artery main trunk occlusive cerebral infarction (P < 0.05). Comparison of the frequency grades of epileptic seizures in patients with acute large artery main trunk occlusive cerebral infarction treated with different drugs showed no statistically significant difference (P > 0.05).Conclusion Aspirin may reduce the occurrence of epilepsy after acute large artery main trunk occlusive cerebral infarction.
