Abstract:
Objective To analyze the hemodynamic characteristics in patients with iron deficiency anemia(IDA) using transcranial Doppler ultrasonography(TCD),and to discuss the diagnostic value of it.Methods There were 46 patients with IDA,among them 28 patients had moderate or severe anemia,and 18 patients had mild anemia.Hemodynamic changes in patients were observed with TCD,and compared with 40 case healthy controls. Results In addition to 3 case results of TCD were normal,the increase of velocity were found in the others patients.The cerenbral blood flow velocity of the moderate or severe anemia group were significantly higher than that of the mild anemia group(P<0.05),and these were significantly higher than that of the control group(P<0.01).The pulsatility index of the moderate or severe anemia group were significantly lower than that of the control group(P<0.01).2 case artery stenosis in 46 patients were found by TCD,there were 5 case with syncope in 46 patients.Conclusion The severness of anemia can be observed by the increased cerenbral blood flow velocities.TCD may be evaluat Effestiveness of blood flow,and TCD may be possible to raise the discover rate of artery stenosis in anemia.
