The diagnostic value of combined TCD and CTA in intracranial arterial stenosis

To investigate the clinical diagnostic value of computed tomographic angiography (CTA)and transcranial Doppler (TCD)used separately and in combination for intracranial arterial stenosis. Methods: A total of 47 patients diagnosed with acute ischemic stroke at the Second Affiliated Hospital of Qiqihar Medical University from June 2015 to June 2016 were selected as the study subjects. All patients underwent both TCD and CTA examinations, followed by digital subtraction angiography (DSA). Results: Using DSA as the gold standard, the results of TCD and CTA were evaluated. Among the 47 patients, a total of 67 intracranial arterial stenoses were detected by DSA.TCD identified 53 stenoses, CTA identified 52 stenoses, and the combined diagnosis of CTA and TCD identified 64 stenoses. The combined diagnosis of CTA and TCD was significantly higher than that of a single examination method.().Conclusion: The combined diagnosis of intracranial arterial stenosis using TCD and CTA can avoid missed diagnoses and provides a reliable basis for clinical decision-making, offering an objective foundation for further clinical treatment.
