Summary

Angiography guides embolization for acute upper GI bleeding and aids lower GI bleeding management. Despite intermittent bleeding challenges, it offers minimally invasive localization and control.

Area of Science:

  • Gastroenterology
  • Interventional Radiology

Background:

  • Acute gastrointestinal (GI) bleeding presents significant diagnostic and therapeutic challenges.
  • Traditional diagnostic methods may be limited in identifying the source of active bleeding.

Purpose of the Study:

  • To evaluate the diagnostic and therapeutic utility of angiography in managing acute upper and lower GI tract bleeding.
  • To highlight the role of angiography in guiding selective embolization procedures.

Main Methods:

  • Utilized angiography for selective embolization of arteries supplying the upper GI tract, including the left gastric artery and gastroduodenal artery branches.
  • Applied angiographic catheter techniques for diagnostic and therapeutic support in lower GI bleeding cases.

Main Results:

  • Angiography primarily serves a therapeutic role in upper GI bleeding by guiding selective embolization.
  • Angiographic catheter techniques offer diagnostic and therapeutic benefits for various lower GI bleeding sources.
  • Minimal invasiveness and low risk are key advantages of angiographic interventions.

Conclusions:

  • Angiography is a crucial tool for both localizing and controlling acute GI bleeding, particularly when bleeding is intermittent.
  • The therapeutic application of angiography, especially through selective embolization, is highly effective.
  • Despite challenges posed by intermittent bleeding, angiography remains a valuable, minimally invasive option for managing GI hemorrhage.
