ABSTRACT
Objective To evaluate the changes of middle cerebral arterial (MCA) hemodynamics before and after intraluminal stent-assisted angioplasty for their stenosis. Methods A total of 11 patients with MCA stenosis treated by intraluminal stent-assisted angioplasty were selected. In these cases, their stenosis before treatment and the state of stents after treatment were observed using transcranial color Doppler ultrasonography(TCCD). Meanwhile, the blood flow velocities (including peak systolic velocity, end diastolic velocity and mean velocity) were measured and studied comparatively at stenosis and post-stenosis place before and after the treatment, respectively. Results ①Among 11 cases implanted stents, 10 stents were in good state after treatment, only one expanded incompletely. ②The blood flow velocities were significantly higher in patients at stenosis place than in normal adults, and lower at post-stenosis place before treatment (P<0.05). The blood flow velocity lowered obviously at stenosis place after treatment (P<0.05) ,among which 90.9% were restored. The one which expanded incompletely was slightly higher. The blood flow velocity increased at post-stenosis place after treatment (P<0.05) and all returned to normal.Conclusions TCCD can observe the MCA stenosis and the state of stent,and analyze the changes of their hemodynamics.
ABSTRACT
Objective To discuss the value of network with real-time monitoring case in hospital. Methods Using the real time monitoring case of "No.1 Military Medical Project" and examining, analysis and evaluating. Results The quality of case and medical care were advanced obviously. Conclusion The scientification and standardization of case realized is propitious for hospital management.
