| Objective To investigate the characteristics of cerebral hemodynamics in patients with anemia of different degrees and analyze the changes of cerebral blood flow after treatment. Methods A total of 68 patients with anemia were selected from the outpatient and inpatient Department of Hematology of Hefei Second People's Hospital from June 2018 to January 2020. According to the severity of anemia, the patients were divided into mild anemia group (32 cases) and moderate severe anemia group (36 cases). At the same time, 30 healthy outpatients were taken as the control group. The difference in cerebral blood flow velocity in each group was detected by transcranial Doppler ultrasound.The changes of cerebral blood flow velocity in two anemia groups were compared before and after treatment. Results The Vm of blood vessels (LMCA, RMCA, BA, LVA and RVA) in moderate and severe anemia group was faster than that in mild anemia group and control group (P<0.05), and there was no difference between mild anemia group and control group (P>0.05). After treatment, Vm of blood vessels in patients with moderate severe anemia was significantly lower than that before treatment (P<0.05), but there was no significant difference in Vm of each vessel between patients with mild anemia and those before treatment (P>0.05). The Vm of LMCA, BA, LVA and RVA in moderate severe anemia group was significantly higher than that in mild anemia group (P<0.05), while the Vm of RMCA had no significant difference compared with that in mild anemia group (P>0.05). Conclusions Moderate and severe anemia can cause reversible increase of cerebral blood flow velocity. Monitoring cerebral blood flow velocity in patients with anemia may play a guiding role in the treatment. |
