Angiography in gastrointestinal bleeding in children

Insights

Arteriography correctly diagnosed gastrointestinal bleeding in 64% of pediatric patients, with higher accuracy for acute bleeds. This diagnostic tool aids in identifying causes like ulcers and vascular malformations.

Area of Science:

  • Pediatric Gastroenterology
  • Diagnostic Imaging
  • Interventional Radiology

Background:

  • Gastrointestinal bleeding is a significant concern in children.
  • Accurate diagnosis is crucial for effective management.
  • Arteriography is a potential tool for identifying bleeding sources in pediatric patients.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of arteriography in pediatric patients with acute or chronic gastrointestinal bleeding.
  • To identify common causes of gastrointestinal bleeding in this age group.

Main Methods:

  • Retrospective review of 27 pediatric patients (1 day to 16 years) undergoing arteriography for gastrointestinal bleeding.
  • Exclusion of patients with known esophageal varices and portal hypertension.
  • Final diagnosis confirmed through surgery, endoscopy, biopsy, laboratory data, and clinical follow-up.

Main Results:

  • Arteriography provided a correct diagnosis in 64% of 25 cases, with a 36% false-negative rate.
  • Diagnostic accuracy was higher in acute gastrointestinal bleeding (71% correct, 29% false-negative) compared to chronic/recurrent bleeding (55% correct, 45% false-negative).
  • Common causes included gastric/duodenal ulcers, gastritis, vascular malformations, and typhlitis. Transcatheter therapy had a 50% success rate in acute bleeders.

Conclusions:

  • Arteriography is a valuable diagnostic tool for pediatric gastrointestinal bleeding, particularly for acute cases.
  • The study identified key causes of bleeding in children, guiding further management strategies.
  • Transcatheter therapy offers a potential treatment option for selected acute bleeding events.
