【 摘 要 】

BACKGROUND: Environmental factors interfere on sickle cell anaemia (SCA). Transcanial Doppler (TCD) is important to evaluate cerebrovascular disease. OBJECTIVE: To evaluate brain haemodynamic profile of children with SCA in Sergipe. METHODS: Cross sectional study (group1: SCA patients aged 3-18; group2: age and sex matched healthy individuals). Baseline brain flow was evaluated. RESULTS: Group1=34 patients; group 2=81 controls. SCA patients had mean velocity (MV)=125.69 cm/s±23.40; pulsatility index (PI)=0.66±0.10; middle cerebral artery ratio (MCAr)=14.53±15.23; right anterior cerebral artery/right middle cerebral artery=0.77±0.20; left anterior cerebral artery/left middle cerebral artery=0.78±0.20. Controls had MV=79.44±15.54; PI=0.82±0.11; MCAr=13.19±13.77; right anterior cerebral artery/right middle cerebral artery=0.80±0.16; left anterior cerebral artery/left middle cerebral artery=0.84±0.18. MV and PI differences were statistically significant between groups. MV was related to age but not to gender. CONCLUSION: MV evaluation using TCD was similar to international standards and possible to be used in our setting.
