Abstract:
Objective To explore the changes of cerebral vasoreactivity(CVR) in patients with acute cerebral infarction of various clinical subtypes.Methods The 70 patients with acute cerebral infarction were divided into 3 subtypes:atherothrombotic infarction (AI)group(n=22), lacunar infarction (LI)group(n=33), cardiogenic infarction (CI)group(n=15).The mean blood flow velocity (Vm), pulse index(PI), resistance index(RI) in bilateral middle cerebral artery(MCA) were detected, and breath holding index (BHI) was measured by TCD in these patients through breath holding test. All the data were compared with the health controls. Results Compared with normal control group,the Vm,PI and RI were significantly increased (P0.05). Conclusions There are differents in CVR in patients with acute cerebral infarction of various subtypes. The damage of CVR is more obviously in AI and LI group. There is clinical significance for measurement of CVR to evaluate the haemodynamic changes in various subtype of acute cerebral infarction.
