Some Sickle Cell Patients Fear Stroke #30forSickleCell

Even Children with SCD are at risk for strokes #30forSickleCell #SickleCellAnemia

One common complications of sickle cell disease and sickle cell anemia (SCA) is a stroke. Children, even babies are at risk of having a stroke because their sickled hemoglobin could possibly block blood flow and prevent oxygen from going to their brain properly. Reports show that a stroke occurs when the large arteries are damaged by the sickled red blood cells, which  stick to the vessel walls in the patient’s brain (source).

“SCD children have a 67 percent risk of recurrence with strokes recurring up to nine months apart. [In addition,] it’s estimated that 17 percent of SCD children under the age of 14 have silent strokes and the rate increases to 23 percent by the age of 18, with the size and number of lesions increasing. (source).”

Doctor’s monitor the blood flow in a child’s brain annually with a Transcranial Dopplar Test (TCD). The test is given with an ultra sound machine, which helps the technician listen to blood flow and take pictures of the patients brain waves.

One of the treatments to prevent a stroke is for at-risk patients with sickle cell to receive blood transfusions.

What are some of the risk factors associated with a stroke in patients with SCA?

According to a report from the American Society of Hematology

Factors such as low hemoglobin levels, increased systolic blood pressure, and male gender are linked to a higher risk of silent cerebral infarcts, or silent strokes, in children with sickle cell anemia, according to results from a large, first-of-its-kind study. (source)

To learn more about the subject, I recommend Blood Journal’s article “Sickle cell disease and stroke” by Luis A. Verduzco and David G. Nathan.
