Emergency arteriography in acute gastrointestinal bleeding.
British Medical Journal
|April 17, 1976
Summary
Emergency arteriography accurately identifies gastrointestinal bleeding sites in 77% of patients. While diagnostic arteriography is recommended, its therapeutic use for chronic ulcers is limited, requiring further study for acute lesions.
Area of Science:
- Gastroenterology
- Interventional Radiology
Background:
- Acute gastrointestinal bleeding poses diagnostic and therapeutic challenges.
- Endoscopic methods may not always localize the bleeding source effectively.
Purpose of the Study:
- To evaluate the diagnostic and therapeutic utility of emergency arteriography in acute gastrointestinal bleeding.
- To determine the efficacy of intra-arterial vasoconstrictor infusions.
Main Methods:
- Emergency arteriography performed on 35 patients with acute gastrointestinal bleeding.
- Intra-arterial vasoconstrictor infusions administered as pre-surgical or definitive treatment.
- Correlation of arteriographic findings with surgical confirmation.
Main Results:
- Arteriography identified a definite bleeding site in 77% (27/35) of patients.
- Surgical confirmation of bleeding site achieved in 20/23 patients.
- Vasoconstrictor infusion temporarily controlled bleeding in 6/7 patients pre-surgery; 4/10 patients with chronic ulcers experienced re-bleeding after definitive infusion therapy.
Conclusions:
- Diagnostic arteriography is recommended for active gastrointestinal bleeding when endoscopy is inconclusive.
- Therapeutic arteriography with vasoconstrictors is not recommended for chronic ulcer bleeding, except for pre-surgical resuscitation.
- Further research is needed to define the role of therapeutic arteriography in acute lesions.
