    Summary

    Gastric bleeding often originates from a single site, typically in the stomach's upper part, frequently supplied by the left gastric artery. This finding aids in diagnosing and treating gastrointestinal hemorrhage.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology
    • Medical Diagnostics

    Background:

    • Gastric bleeding is a significant clinical concern.
    • Accurate localization of bleeding is crucial for effective treatment.
    • Arteriography is a key diagnostic tool for identifying active gastrointestinal hemorrhage.

    Purpose of the Study:

    • To analyze arteriographic findings in patients with clinical gastric bleeding.
    • To determine the common location, number, and arterial supply of extravasation points.
    • To compare angiographic and endoscopic findings in identifying gastric bleeding sites.

    Main Methods:

    • Review of arteriograms from 103 patients with clinical gastric bleeding.
    • Correlation of angiographic findings with endoscopic observations.
    • Analysis of patient conditions, including stress related to surgery, trauma, or sepsis.

    Main Results:

    • A single extravasation point was identified in 98% of cases.
    • The proximal stomach was the bleeding site in 92% of patients.
    • The left gastric artery was the source in 85% of cases.
    • Angiography and endoscopy agreement varied based on observed active bleeding.
    • In patients with stress-related conditions (57%), 95% had proximal gastric extravasation.

    Conclusions:

    • Gastric bleeding identified via arteriography is predominantly a single-point event.
    • The proximal stomach is the most common site of extravasation.
    • The left gastric artery is the most frequent supplier of gastric bleeding.
    • Arteriography is a reliable method for localizing gastric bleeding, especially in critically ill patients.
