[Angiography in acute gactrointestinal hemorrhage]

|May 24, 1975
Summary
Visceral angiography successfully localized the source of acute gastrointestinal bleeding in two thirds of emergency cases. However, the exact cause remained unclear in one third of patients, highlighting limitations in diagnosing bleeding origins.
Area of Science:
- Radiology
- Gastroenterology
- Vascular Imaging
Context:
- Acute gastrointestinal bleeding presents a diagnostic challenge.
- Visceral angiography is an emergency imaging modality.
- Evaluating the diagnostic yield of angiography in this setting is crucial.
Purpose:
- To assess the diagnostic value and indications of visceral angiography.
- To evaluate the success rate of localizing bleeding sources in acute gastrointestinal bleeding.
Summary:
- Visceral angiography was performed in 30 cases of acute gastrointestinal bleeding.
- The bleeding source was localized in two thirds of the cases.
- In half of positive angiograms, contrast extravasation was directly visualized; in the other half, pathological findings were identified without extravasation.
Impact:
- Visceral angiography is effective in localizing bleeding sites in a majority of acute gastrointestinal bleeding cases.
- The study identifies limitations where the etiology of bleeding may not be demonstrated.
- Findings inform clinical decision-making regarding the use of angiography in gastrointestinal hemorrhage.
