Erratum: Peak systolic velocity of carotid artery disease could reflect the pathophysiology of atherothrombotic brain infarction [Neurosonology 2022;35:104-109.]

Middle cerebral artery peak systolic velocity: technique and variability.

OBJECTIVE Assessment of the middle cerebral artery (MCA) peak systolic velocity (PSV) can accurately diagnose fetal anemia and has decreased the number of invasive procedures, such as amniocentesis and cordocentesis. The objective of this investigation was to evaluate the intraobserver and interobserver variability as a measure of reproducibility of MCA PSV. The technique of correctly sampling ...

The pathophysiology of watershed infarction in internal carotid artery disease: review of cerebral perfusion studies.

BACKGROUND AND PURPOSE In carotid disease, infarcts can occur in the cortical as well as internal watershed (WS), or both. Better understanding the pathophysiology of WS infarcts would guide treatment. Two distinct hypotheses, namely low-flow and micro-embolism, are equally supported by neuropathological and physiological studies. Here we review the evidence regarding the mechanisms for WS stro...

Peak Systolic Velocity of Superior Thyroid Artery for the Differential Diagnosis of Thyrotoxicosis

AIM The differentiation of destruction-induced thyrotoxicosis and Graves' disease (GD) is of great importance for selection of proper therapy. Radioactive iodine uptake (RAIU) is the gold standard for differentiating these two conditions but its application has remained somewhat limited. Thyroid color Doppler flow sonography (CDFS) is a potential alternative of RAIU but more supporting evidence...

Carotid artery thrombosis and cerebral infarction after multiple traumas

Carotid artery thrombosis and concomitant brain infarction after blunt trauma are rare conditions. We report a 34-year-old woman with multiple traumas due to pedestrian car accident. At the time of initial visiting, she was somnolent and her Glasgow coma scale (GCS) score was 14. Initial vital signs (V/S) and brain computed tomography (CT) scan were normal. One day after admission to the emerge...
