Diagnostic Value of Transcranial Doppler Ultrasound for Evaluating Neonatal Craniocerebral Injuries

This study aims to evaluate the diagnostic value of transcranial Doppler ultrasonography (TCD) for evaluating neonatal craniocerebral injuries.

A high-risk neonate refers to an infant, irrespective of gestational age or birth weight, who exhibits an elevated likelihood of experiencing health complications or death. Preterm infants, defined as those born alive at a gestational age of less than 37 weeks, have seen increased birth and survival rates due to advancements in medical technology and the widespread establishment of Neonatal Intensive Care Units (NICUs). Neonatal sepsis is one of the leading causes of morbidity and mortality among term and preterm infants worldwide. Transcranial Doppler ultrasonography (TCD) is the only noninvasive method that enables reliable evaluation of blood flow in the basal intracerebral vessels, providing physiological information complementary to anatomic imaging. TCD is relatively inexpensive, can be performed at the bedside, and enables monitoring in acute emergency settings and for prolonged periods with high temporal resolution, making it ideal for studying dynamic cerebrovascular responses.
