Abstract
Aim:To investigate the value of transcranial Doppler (TCD) in haemodynamic monitoring of sub-clinical epilepsy. Methods:Thirty patients with sub-clinical epilepsy were continuously monitored by TCD and electroencephalogram (EEG). TCD data of five time points were analyzed, including 1 min before sub-clinical epilepsy attack, 1,5,10,and,20 min after sub-clinical epilepsy attack. Results: There were significant differences of systolic velocity (vs) , mean velocity (vm) , diastolic velocity (vd) , pulsatility index (PI) of middle cerebral artery ( MCA) and heart rate (HR) between pre-and post- sub-clinical epilepsy (F = 69.880, 78.716, 58.393, 119.209, and 164.268, P<0.001).vs, vm, vd and HR reached the peek ( P < 0. 001 ) , and PI was lowest 1 min after sub-clinical epilepsy attack ( P < 0. 001 ). Conclusion: There is typical haemodynamic change during sub-clinical epilepsy attack. Abrupt increase of cerebral blood flow in TCD shows that there will be sub-clinical epilepsy attack.关键词
