Transcranial doppler in sickle cell anaemia: evaluation of brain blood flow parameters in children of Aracaju, Northeast-Brazil
Environmental factors interfere on sickle cell anaemia (SCA). Transcanial Doppler (TCD) is important to evaluate cerebrovascular disease. To evaluate brain haemodynamic profile of children with SCA in Sergipe. Cross sectional study (group1: SCA patients aged 3-18; group2: age and sex matched healthy...

| description | Environmental factors interfere on sickle cell anaemia (SCA). Transcanial Doppler (TCD) is important to evaluate cerebrovascular disease.
To evaluate brain haemodynamic profile of children with SCA in Sergipe.
Cross sectional study (group1: SCA patients aged 3-18; group2: age and sex matched healthy individuals). Baseline brain flow was evaluated.
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.
MV evaluation using TCD was similar to international standards and possible to be used in our setting. |
