Abstract:
Objective To evaluate the relationship between intraplaque hemorrhage of cerebral arteries and acute cerebral infarcts. Methods 35 patients with severe stenosis in M1 segment of middle cerebral arteries (MCA)were included in this study.Intracranial TOF MRA (time of flight MR angiography)was performed to detect the stenosis in MCA,and DWI (diffusion weighted imaging) was performed to detect cerebral acute infarcts.T1 MPRAGE sequence was positioned on the stenosis in M1 segment of MCA,and intraplaque hemorrhage was determined according to high signal on T1 MRRAGE images.35 patients were divided into two groups:one group with intraplaque hemorrhage and the other group without intraplaque hemorrhage.Whether there was significant differ-ence in the incidences of acute cerebral infarcts between the two groups were determined byχ2 test.Results Intraplaque hemorrhage was detected in 1 5 patients,in which 12 patients had acute cerebral infarcts.There were no intraplaque hemorrhage in 20 patients,in which 9 patients had acute cerebral infarcts.There was significant difference in the incidences of acute cerebral infarcts between the two groups (P =0.046 <0.05).Conclusion There is a higher incidence of acute cerebral infarcts in patients with intraplaque hem-orrhage than those without intraplaque hemorrhage.Intraplaque hemorrhage in severe stenosis of cerebral arteries is a high-risk indi-cation for acute cerebral infarction.
