Transcranial doppler (TCD) is an accurate and non‐invasive method to determine stroke risk. 2004-08-24 Transcranial Doppler screening in sickle cell disease: The implications of using peak systolic criteria Lena N Naffaa, Yasmeen K Tandon, Neville Irani Lena N Naffaa, Department of Radiology, Akron Children’s Hospital, Akron, OH 44308, United States 2012-09-01 Children with sickle cell disease (SCD) are at high risk for stroke. 1 – 3 The risk is highest in children with elevated blood flow velocity in the distal internal carotid (terminal internal carotid artery) or proximal middle cerebral artery (MCA), as measured with transcranial Doppler ultrasonography (TCD). 4 Chronic blood transfusions, if implemented in a timely fashion in those with flow velocity >200 cm/s, can … 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. CONCLUSIONS: Transcranial Doppler is sensitive and specific for the detection of arterial vasculopathy of sickle cell disease. Screening should include a transorbital examination of the distal internal carotid artery as well as examination using the transtemporal approach.

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. 2012-09-01 Transcranial Doppler US has become a mainstay in the intensive care unit for the evaluation and management of vasospasm secondary to subarachnoid hemorrhage. This imaging study is also useful for evaluating the intracranial vasculature in the settings of stroke, sickle cell … 2011-09-01 2020-06-02 SCD, Transcranial Doppler (TCD) & Stroke TCD is used to evaluate cerebral arterial hemodynamics, and it plays an important role in screening and providing a prognosis for SCD patients. The stroke prevention trials in sickle cell anemia (STOP trials I and II) used TCD to screen and identify SCD patients who were at the greatest risk of ischemic stroke. Changes on Transcranial Doppler (TCD) ultrasonography have been proposed as significant predictors of cerebrovascular complications in sickle cell disease (SCD).

Transcranial Doppler scanning in Children with SCD.1,2. HbSC patients There is no national recommendation for the screening of children with HbSC sickle cell disease.

Hydroxyurea has hematologic and clinical efficacy in sickle cell anemia (SCA), but its effects on transcranial Doppler (TCD) flow velocities remain undefined.
