Abstract

High blood flow velocity in the middle cerebral artery or distal internal carotid artery, as measured by nonduplex transcranial Doppler sonography, predicts stroke in children with sickle cell anemia. However, velocities measured using the more widely available duplex transcranial Doppler imaging equipment may not be comparable. We sought to determine the magnitude and significance of the potential differences. We performed 55 paired examinations with duplex imaging and nonduplex nonimaging sonography machines on 53 children with sickle cell anemia. Examinations were performed consecutively by three sonographers blinded to the results of the opposing study. Velocities were measured in five clinically relevant vessels. Time-averaged mean maximum (TAMx) velocity measurements obtained with the duplex equipment were significantly lower than those made with the nonduplex equipment for all vessels except the posterior cerebral artery. The mean differences were 10.9% (p < 0.0001) in the middle cerebral artery, 12.7% (p = 0.002) in the anterior cerebral artery, 2.2% (p = 0.69) in the posterior cerebral artery, 21.0% (p < 0.0001) in the distal internal carotid artery, and 15.3% (p < 0.0001) at the bifurcation of the distal internal caro...Continue Reading

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
