Preliminary application of contrast-enhanced transcranial color-coded sonography in subacute intracerebral hemorrhage

Objective To observe the ultrasonographic findings of patients with basal ganglia hemorrhage by transcranial color-code sonography (TCCS) and contrast-enhanced transcranial color-code sonography (CE-TCCS), and to evaluate the clinical value of TCCS and CE-TCCS in assessing the cerebral perfusion with basal ganglia hemorrhage. Methods Eighty-two patients with basal ganglia hemorrhage were selected, and hematoma was seen in 58 patients (70.7%). Forty-six cases of bilateral TCCS with clear display of basal ganglia through temporal window were selected. CE-TCCS was used to observe cerebral perfusion of edema zone, edema zone edge and peripheral brain parenchyma. Results The bilateral rate displayed by TCCS was 79.3%. Among 58 cases, 30 cases had ventricular compression, 14 cases had hematoma rupture into ventricle, 8 cases had midline displacement, and 10 cases had no complication change. The cerebral perfusion in edema areas around hematoma was reduced by CE-TCCS, but the degree of reduction was different. There were reduced in a step-like manner in the cerebral perfusion from edema zone and edema zone edge to peripheral brain tissue. Conclusions CE-TCCS is a new method for clinical diagnosis and monitoring the progress of treatments of cerebral hematoma.
