Abstract:
Objective To explore the characteristic of transcranial color-coded sonography(TCCS)and contrast-enhanced transcranial color-coded sonography (CE-TCCS) in patients with intracerebral hemorrhage and thiers clinical value.Methods 66 patients were randomly selected,whose preliminary clinical diagnosis were intracerebral hemorrhage (ICH).The patients were followed up by TCCS in acute phase,subacute phase and chronic phase.The changes of the echo,boundary and the hematoma volume were recorded in different stages.In acute phase,patients' complications of intracerebral structure were observed.32 patients were selected randomly to underwent CE-TCCS examination in the subacute phase.The size,shape and the perfusion situation of hematoma were observed.The results of CE-TCCS were compared with the results of TCCS.Correlation analysis was made between the results of ultrasound and CT scan.Results (1) CT results:61 patients (61/66) were confirmed ICH through CT scan.(2) TCCS results:50 patients (50/61) with ICH could show the bleeding site.TCCS showed that 33 patients with ICH accompanied by intraventricular pressure,haematoma defeats ventricle and midline shift in acute phase.The echo became lower and the boundary became more clear with time.The long diameter,wide diameter,thickness diameter and volume of hematoma in different stages on TCCS had a good correlation with that on CT scan.(3)CE-TCCS results:30 cases of intracerebral hematoma could be clearly displayed the situation of hematoma through the ipsilateral temporal window.Compared with TCCS,CE TCCS had a better correlation with CT scan on the measurement of the hematoma length,width.The images of 2 cases observed through contralateral temporal window failded to be clearly shown.In 7 cases of ICH,visible low-enhanced edema area could be seen around the hematoma.The width of the edema area had a good correlation with the CTP result.Conclusions TCCS could clearly show the bleeding sites,hematoma volume and complications and the features of ICH in different stages of disease.TCCS could be used to monitor the condition of patients with ICH and recognized the disease progression initially.CE-TCCS had a much more clear display of intracerebral hematoma location,shape,boundary.At the same time,CE-TCCS could provide blood perfusion information of surrounding tissue in hematoma so that it could observe the change of peripheral edema more convenient.
