Ware RE, Davis BR, Schultz WH, Brown RC, Aygun B, et al. Hydroxycarbamide versus chronic transfusion for maintenance of transcranial doppler flow velocities in children with sickle cell anaemia

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.

MATERIALS AND METHODS: One hundred sixty-eight examinations in 66 children were performed for sickle cell stroke screening. Hydroxyurea has hematologic and clinical efficacy in sickle cell anemia (SCA), but its effects on transcranial Doppler (TCD) flow velocities remain undefined. 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. Sickle cell anaemia: transcranial doppler Melo et al. chance of occurrence of such event was of 11% up to the second decade of life, but increasing to 40% in the next 3 years for a second ictus6,7.

Sickle cell disease (SCD) is one of the most common causes of stroke in children worldwide. Based on the results of the Stroke Prevention Trial in Sickle Cell Anemia (STOP), annual transcranial Doppler ultrasound (TCD) screening for affected children is standard practice.

Transcranial Doppler ultrasound screening (TCD) is a test that uses ultrasound to measure the velocity or speed of blood flow through the blood vessels in the brain.

Transcranial Doppler (TCD) is a diagnostic tool that can be used at bedside to assess the cerebral vasculature noninvasively. It is inexpensive, safe, and reliable when compared with other techniques. It can be repeated multiple times and can be used for continuous monitoring if needed.

This measure assesses the percentage of children ages 2 through 15 years with sickle cell anemia 1998-03-01 TCD = transcranial Doppler, CBFV = cerebral blood flow velocity. 4. Conclusions. Hematopoietic stem cell transplantation is the only existing curative treatment for sickle cell disease, but the therapy depends on a compatible donor [13]. Transcranial Doppler (TCD) is widely accepted as the modality of choice for screening intracranial vessels in children with sickle cell disease. Its advantages are that it is noninvasive (no need for sedation, contrast material, or radiation), PURPOSE: To determine whether criteria for screening patients with sickle cell anemia for stroke established with a nonimaging transcranial Doppler ultrasonographic (US) technique are applicable to studies performed with a transcranial Doppler US imaging technique.

Transcranial Doppler (TCD) and transcranial color Doppler (TCCD) are types of Doppler The tests are effective for detecting sickle cell disease, ischemic cerebrovascular disease, subarachnoid hemorrhage, arteriovenous malformations,&

Importance: With transcranial Doppler (TCD) screening, we can identify children and adolescents with sickle cell anemia who are at the highest risk of stroke. Children with sickle cell anaemia (SCA) and conditional transcranial Doppler (TCD) [time-averaged mean velocity (TAMV) 170-199 cm/s] have increased risk of primary stroke, but receive no specific therapy. Some will convert to abnormal velocities (TAMV >/=200 cm/s) with further increase in stroke risk.
