Management of Celiac Artery Penetrating Ulcer

Diagnostic Approach

• The American College of Radiology recommends obtaining CT angiography to identify the size and location of the penetrating ulcer, presence of pseudoaneurysm, active contrast extravasation, and involvement of branch vessels 1
• The Society of Interventional Radiology suggests assessing for signs of visceral ischemia including bowel wall thickening, pneumatosis, or portal venous gas 2
• Evaluate the superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) patency, as concurrent disease significantly impacts treatment decisions, according to the Journal of the American College of Radiology 2

Treatment Algorithm

• The Critical Care society recommends immediate catheter angiography with endovascular intervention as the first-line approach for hemodynamically unstable patients or those with evidence of active extravasation 1
• Technical success rates for endovascular stent placement range from 85-100% with lower perioperative risks compared to open surgery, as reported by the Praxis Medical Insights 3

Adjunctive Medical Management

• The American College of Radiology suggests that anticoagulation or antiplatelet therapy should be initiated in conjunction with definitive treatment planning, not as isolated therapy 2
• Systemic anticoagulation prevents thrombus propagation but is not a surrogate for revascularization, according to the Journal of the American College of Radiology 2

Critical Monitoring and Follow-up

• The Critical Care society recommends that visceral perfusion must be monitored clinically and radiologically with follow-up imaging to rule out complications 1
• Monitor for signs of mesenteric ischemia including postprandial pain, weight loss, and food avoidance, as suggested by the Praxis Medical Insights 3, 4
• Watch for late complications including stent migration, fracture, or endoleak requiring reintervention, according to the Praxis Medical Insights 5
