Background : Beta-thalassemia is a type of anemia in which the patients may require splenectomy and this can lead to thrombocytosis with increased risk of stroke.
Transcranial Doppler ultrasound is a method for determining cerebral vessel stenosis.
Objectives : The aim of this study was to investigate whether the risk of a future stroke secondary to cerebral artery stenosis can be predicted with the use of transcranial Doppler ultrasound in beta-thalassemia major patients.
Patients and Methods : This study included 54 beta-thalassemia major patients divided into 2 groups ; group A consisted of 28 patients who have thrombocytosis secondary to a previous splenectomy and group B comprised of 26 patients who did not have a splenectomy with normal platelet count, as well as a control group of 30 healthy individuals.
Results : Transcranial Doppler ultrasound of the cerebral vessels were performed in all participants, and the results for each group were compared with the controls.
In addition, patients were evaluated for evidence of high flow velocity in the cerebral vessels that met the clinically significant criteria of ≥ 50 % stenosis.
Transcranial Doppler ultrasound velocity criteria for & gt ; 50 % stenosis, indicating a risk of stroke, were not documented in any patients but increase in cerebral blood velocities in many arteries in group A and in some arteries in group B were revealed.
Conclusion : Following splenectomy, thrombocytosis can predispose the patients to an increase in cerebral blood velocities more than respected with anemia.
But by transcranial doppler ultrasonography no evidence of significant stenosis were found in intracerebral arteries to conclude that the beta-thalassemia major patients were more prone to the development of stroke secondary to this abnormality.
