Abstract:
Objective To assess the value of approximal side angle of carotid atherosclerotic plaques in patients with cerebral infarction by ultrasonography.Methods One hundred and seventy six patients with carotid atherosclerotic plaques were examined with uItrasonography and divided into two groups:cerebral infarction group (n=67)and none cerebral infarction group(n=109).Vessel area and residual lumen area of carotid artery were measured in axial view using linear probe.Area stenosis rate was calculated.The approximal side angle and thickness of plaque were measured respectively.The results of two groups were compared.Results The approximal side angle of plaque of cerebral group was significantly higher than that of none cerebral infarction groups(P<0.05).The sensitivity and specificity for approximal side angle of plaque(cutoff value:13.0°)were 79.1%,71.6%,respectively.There were no significant difference of area stenosis rate and plaque thickness between two groups(P>0.05).Conclusions The approximal side angle of plaque can be regarded as a novel index to assess the stability of plaque.
