- Abstract:
- Objective To analyze the value of cerebral CT perfusion imaging (CTP) parameters combined with electroencephalogram (EEG) to predict epilepsy secondary to aneurysmal subarachnoid hemorrhage (aSAH) and the prognosis. Methods A total of 78 patients with aSAH were enrolled in the study, including 40 patients receiving CTP combined with EEG examination (combined group), and 38 receiving CTP alone (control group). The dynamic EEG Young type and the detection rates for cerebral vasospasm and epileptiform seizures were compared between two groups. The CTP parameters were compared between patients with and without cerebral vasospasm, and the EEG Young type composition and prognosis were compared patients with and without epileptiform seizures. The predictive value of CTP alone and CTP combined with EEG for the prognosis was analyzed. Results There were 3, 5, 19, 11, and 2 cases of EEG Young types I, II, III, IV, and V in the combined group. The detection rates for cerebral vasospasm and epileptiform seizures in the combined group were higher than those in control group (P<0.05). Compared with patients without cerebral vasospasm, those with cerebral vasospasm had smaller cerebral blood flow and cerebral blood volume, longer time to peak and mean transit time (P<0.05). In the combined group, the composition of EEG types between patients with and without epileptiform seizures were significantly different (P<0.05). Types III and IV predominated in patients with epileptiform seizures, while type Ⅱ in those without epileptiform seizures. The modified Rankin scale scores of patients with epileptiform seizures were higher than those of patients without epileptiform seizures (P<0.05). Compared with control group, the combined group had higher accuracy rate in prognosis assessment (P<0.05). Conclusion Compared with CTP alone, CTP combined with EEG has high predictive value for epilepsy secondary to aSAH and its prognosis, worthy of clinical application.
