Aneurysm of gastroduodenal artery

Last edited: 4/15/2026

Overview

A gastroduodenal artery (GDA) aneurysm is an uncommon visceral aneurysm that frequently presents with spontaneous rupture, leading to significant hemorrhagic complications and high mortality rates. The etiology remains poorly understood 1.

Diagnosis

  • Clinical Presentation: Hemorrhagic shock, abdominal pain 1.
  • Imaging: Contrast-enhanced CT angiography is crucial for diagnosis, visualizing aneurysm location and extent 1.
  • Laboratory Tests: Elevated inflammatory markers, coagulation profile assessment 1.

    • Management

  • Surgical Intervention: Emergent surgical repair or endovascular embolization for ruptured aneurysms 1.
  • Hemodynamic Stabilization: Aggressive resuscitation with blood products to manage hemorrhagic shock 1.
  • Monitoring: Continuous hemodynamic monitoring post-intervention 1.

    • Special Populations

  • Autoimmune History: Patients with significant autoimmune conditions may be at higher risk; tailored management required 1.

    • Key Recommendations

  • Immediate Surgical or Endovascular Intervention for Ruptured Aneurysms (Evidence: Weak) 1
  • Aggressive Hemodynamic Stabilization with Blood Products (Evidence: Weak) 1
  • Utilize Contrast-Enhanced CT Angiography for Diagnosis (Evidence: Weak) 1
