Overview

Diagnostic study evaluates CTA and digital subtraction angiography correlation in gastrointestinal bleeding, highlighting predictive value for culprit artery localization.

Key Points

  • To evaluate the correlation between computed tomography angiography (CTA) and digital subtraction angiography (DSA) in predicting positive findings and identifying culprit bleeding arteries in gastrointestinal hemorrhage.
  • Assessed diagnostic concordance between non-invasive CTA and catheter-directed DSA in patients with gastrointestinal bleeding.
  • Analyzed the predictive accuracy of CTA features for detecting active extravasation and localizing the culprit arterial vessel.
  • CTA findings correspond with digital subtraction angiography in confirming active vascular extravasation.
  • Initial CTA scan characteristics facilitate accurate pre-procedural identification and targeted catheterization of culprit bleeding arteries.
