Accuracy of Transcranial Colour Coded Duplex Compared With CT Angiography in Diagnosing Arterial Obstructions in Acute Ischemic Strokes

What this Trial Is About

Cerebrovascular stroke is a leading cause of death and disability worldwide, with atherosclerosis being a major cause of ischemic strokes through vessel narrowing and blockages. Intracranial stenosis often results in recurrent ischemic strokes or transient ischemic attacks, and its severity can influence the extent of brain injury. The prevalence of intracranial arterial stenosis varies among ethnic groups and is notably common in the Egyptian stroke population. Researchers are evaluating the accuracy of transcranial colour coded duplex, a non-invasive ultrasound tool that measures blood flow velocity and detects blockages in intracranial arteries, compared with CT angiography in patients with acute ischemic strokes or transient ischemic attacks. The study includes patients admitted to the neurology and stroke unit at Sohag University Hospital. Participants will undergo transcranial colour coded duplex and CT angiography to detect arterial obstructions. The study aims to assess the accuracy of the duplex method one year after enrolling 100 patients. Researchers will monitor cerebral blood flow and arterial blockage detection, with no invasive procedures beyond routine imaging. The total participation duration varies but includes comprehensive diagnostic assessments to compare these imaging techniques.
