Assessment of the risk of stroke in children with sickle cell anemia using transcranial doppler ultrasound with imaging in Northwestern Nigeria

Nigerian Journal of Paediatrics, 2023
Background: Stroke is a major cause of morbidity and mortality affecting about 10% of patients with sickle cell anemia (SCA). Transcranial Doppler (TCD) ultrasonography helps to identify children with SCA who are at an increased risk for stroke.

Detection of microemboli by transcranial Doppler ultrasound.

Texas Heart Institute journal, 1997
Doppler ultrasound detection of abnormally high-pitched signals within the arterial waveform offers a new method for diagnosis, and potentially for prediction, of embolic complications in at-risk patients. The nature of Doppler "microembolic" signals is of particular interest in patients with prosthetic heart valves, where a high prevalence of these ...

Microbubble signal properties from PFO tests using transcranial Doppler ultrasound

, 2012
SummaryBackgroundA limitation of transcranial Doppler (TCD) ultrasound is the inability to distinguish tiny benign bubbles from potentially hazardous particulate emboli based on analysis of the intensity of backscattered ultrasound.

Cerebral autoregulation in normal pregnancy, preeclampsia, and 1‐year postpartum

Pregnancy, Volume 2, Issue 4, July 2026.
Abstract Introduction Cerebral complications of preeclampsia pose a significant threat to pregnant women worldwide. The underlying pathophysiology is unclear, but impaired cerebral autoregulation may contribute to adverse maternal outcomes. Long‐term consequences of preeclampsia include cerebrovascular disease, and impairment of cerebral autoregulation

Cerebrovascular reactivity and plasma p‐tau181 in Alzheimer's disease: Insights into APOE‐related vascular phenotypes

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 3, July/September 2026.
Abstract INTRODUCTION Vascular dysfunction is increasingly recognized as a key contributor to Alzheimer's disease (AD). This study explored cerebrovascular reactivity (CVR), measured by the breath‐holding index (BHI) via Transcranial Doppler (TCD), in relation to plasma AD biomarkers, metabolic dysfunction, cardiovascular burden, and apolipoprotein E ...

Early Versus Late Wake‐Up Call After Out‐Of‐Hospital Cardiac Arrest: Protocol for a Multicenter Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest (DANOHCA) Trial

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Background Survivors of out‐of‐hospital cardiac arrest (OHCA) who remain comatose after return of spontaneous circulation are routinely sedated and mechanically ventilated during early post‐resuscitation care. Although prolonged sedation has traditionally been considered necessary, contemporary normothermia‐based temperature control allows ...

Academic and cerebrovascular outcomes after neurodevelopmental screening in sickle cell disease: A longitudinal cohort study

Developmental Medicine &Child Neurology, Volume 68, Issue 7, Page 916-924, July 2026.
Neurodevelopmental screening in toddlers or preschoolers with sickle cell disease (SCD) predicts future academic deficits. Screening sensitivity for future academic deficits is highest in preschoolers with SCD. Brief neurodevelopmental screening tools can identify high risk children for early intervention.

Unusual Evidence of Fat Embolism in the Subclavian Vein Detected by High-Intensity Transient Signals

Methodist DeBakey Cardiovascular Journal
Fat emboli may occur in patients after traumatic fractures or orthopedic procedures; however, their clinical detection is a very rare finding. Here, we describe a 77-year-old female who was admitted to the emergency department with a fracture of the ...
