1 Transcranial Doppler ultrasound (TCD) measurements of the large intracranial vessels' blood flow velocities are effective in identifying children with SCA at highest risk Background: Transcranial Doppler (TCD) is used to select children with sickle cell disease (SCD) for primary stroke prevention using regular blood transfusion. Whether it can also identify high stroke risk in adults with SCD is not known. Methods: The authors examined 112 adult patients from two convenience population samples with SCD and 53 healthy control subjects to compare velocities in High incidence of cerebrovascular accidents in children and adults with SCD prior to the onset of primary stroke prevention with transcranial Doppler (TCD) and regular blood transfusion or hydroxyurea. Data from the 3647 children and adults with SCD followed prospectively from 1978 to 1988 in the Cooperative Study for Sickle Cell Disease cohort.

It was first used clinically Sickle cell anemia is associated with an elevated risk of stroke; without intervention, reports indicate that 10% of children with sickle cell anemia will have a stroke prior to the age of 20 years.

Children with sickle cell disease (SCD) are at risk of vascular occlusions. If this occurs in the brain, it can result in stroke. Stroke is the leading cause of death and disability in children with SCD. Transcranial Doppler (TCD) has been shown to accurately predict those children at risk of stroke so appropriate preventative treatment can commence.

Transcranial Doppler (TCD) is an ultrasonographic method that uses 1 to 2 MHz puls-es which can penetrate skull. It was first used clinically Sickle cell anemia is associated with an elevated risk of stroke; without intervention, reports indicate that 10% of children with sickle cell anemia will have a stroke prior to the age of 20 years. 5,6 Elevated cerebral blood velocities are associated with an increased risk of stroke, which can be assessed using transcranial Doppler (TCD) screening. 7 The Stroke Prevention Trial in Sickle Transcranial Doppler ultrasound screening measures the speed of blood flow through the blood vessels in the brain, predicting the risk of stroke in SCD. *** Sickle Cell Anemia News is strictly a news and information website about the disease.

Transcranial Doppler ultrasound screening measures the speed of blood flow through the blood vessels in the brain, predicting the risk of stroke in SCD. *** Sickle Cell Anemia News is strictly a news and information website about the disease.

For children with sickle cell anaemia and high transcranial doppler (TCD) flow velocities, regular blood transfusions can effectively prevent primary stroke, but must be continued indefinitely. The efficacy of hydroxycarbamide (hydroxyurea) in this setting is unknown; we performed the TWiTCH trial to compare hydroxyurea with standard transfusions.
