867 Transcranial Doppler Ultrasound for the Diagnosis of Cerebral Vasospasm After Aneurysmal Subarachnoid Haemorrhage

Abstract Aim This study aims to review the literature regarding utility and accuracy of transcranial toppler (TCD) ultrasound in diagnosis cerebral vasospasm (CV) following aneurysmal subarachnoid haemorrhage (aSAH). Method A systematic was conducted PRISMA guidelines. Pubmed Google Scholar online databases were searched using designated MeSH search terms: “subarachnoid haemorrhage” AND “aneurysm” “aneurysmal” “cerebral vasospasm” “vasospasm” “transcranial Doppler” “TCD”. Results limited publications not older than 10 years prior this research (May-June 2020) restricted English language. All articles found through screened their titles, then abstract finally from reading full. The remaining by previously set inclusion exclusion criteria. Finally, a further cross-reference completed order include missed database research. yielded 1378 results. Of these, screening process, 6 papers included study. total 403 patients extracted data. number reported diagnoses CV 172. percentage with calculated for each overall, an average 42.68% diagnosed CV. TCD showed have sensitivity specificity 68% 74%, respectively 71% accuracy. Conclusion is useful diagnostic tool that could help predicting early diagnosing occurrence CV, good sensitivity, specificity,
