A Clinical Study Of The Effect Of Aemodynamy On Treating Acute Cerebral Infarction With The Contralateral Needling

Objective: To investigate the effect of the cerebral hemodynamics monitored by TCD and the improvement of scores of neurologic impairment in the patients of acute cerebral infarction treated with the contralateral needling .Methods: 30 cases were treated with the contralateral needling and another 30 cases were treated with the non-contralateral needling . The variety of the mean blood flow velocity (Vm) of the cerebral middle artery (MCA) and the pulsatile index (PI) which were monitored by Transcranial Doppler Ultrasonography(TCD) was observed. The improvement of the scores of neurologic impairment was appraised.Results: 1 , Both Vm of the two side of MCA and the scores of neurologic impairment apparently decreased (P<0.01). In both two groups ,the significant decreasing was observed in Vm of the two side of MCA and the scores of neurologic impairment (PO.01). The scores of neurologic impairment in the contralateral needling group decreased much significantly than that in the non-contralateral needling group (P<0.05). 2, It was much significant that the decrease of Vm of MCA in the side of cerebral infarction was less than that in the side of cerebral non-infarction in the contralateral needling group (P<0.01) and that the decrease of Vm of MCA in the side of cerebral infarction was more than that in the side of cerebral non-infarction in the non-contralateral needling group (P<0.01). It was much significant that the ratio of Vm of pre-treatment to Vm of post-treatment in the side of cerebral infarction is smaller than that in side of the cerebral non-infarction in the contralateral needling group (P<0.01) and that the ratio in the side of cerebral infarction was bigger than that in side of the cerebral non-infarction in the non-contralateral needling group (P<0.01). 3, It wassignificant that the decrease of Vm of MCA in the side of cerebral infarction in the contralateral needling group was less than that in the non-contralateral needling group (P<0.01) and that the decrease of Vm of MCA in the side of cerebral non-infarction in the contralateral needling group was more than that in the non-contralateral needling group (P<0.01). It was significant that the ratio of Vm of pre-treatment to Vm of post-treatment in the side of cerebral infarction in the contralateral needling group was smaller than that in the non-contralateral needling group and that the ratio in the side of non-cerebral in the contralateral needling group was bigger than that in the non-contralateral needling group (P<0.01). 4, In both two groups , the changes of the pulsatile index (PI) were not obvious after therapy (P>0.05).Conclusions: 1 , Vm of MCA in the side of cerebral infarction in both groups had decreased and it was impossibly indicated that the cerebral vessels were expanded so that the cerebral blood flow increased. 2, The scores of neurologic impairment apparently decreased in the two groups. The contralateral needling and the non-contralateral needling were the effective ways of treating acute cerebral infarction patients. 3, The decrease of Vm of MCA in the side of cerebral infarction in the contralateral needling group was less than that in the non-contralateral needling group. The decrease of the scores of neurologic impairment in the contralateral needling group was more than that in the non-contralateral needling group. The contralateral needling was superior to the non-contralateral needling in elevating cure rates and reducing sequelae . 4, TCD is one of the way of researching acute cerebral infarction patients treated by contralateral needling and non-contralateral needling.
