Management of Severe Celiac Trunk Stenosis

Initial Diagnostic Evaluation

The American College of Radiology recommends CT angiography (CTA) as the initial imaging modality of choice, with 95-100% sensitivity and specificity for detecting mesenteric vascular abnormalities, in patients with suspected celiac trunk stenosis 1, 2
Imaging should look specifically for atherosclerotic calcified plaque at the celiac origin versus "J-shaped" proximal narrowing, suggesting median arcuate ligament (MAL) compression, as well as presence and extent of collateral circulation, particularly pancreaticoduodenal arcades from the superior mesenteric artery (SMA) 1
Involvement of other mesenteric vessels (SMA, IMA) should be evaluated, as multi-vessel disease significantly impacts treatment decisions 1

For atherosclerotic celiac trunk stenosis, endovascular therapy with angioplasty and stent placement is the first-line treatment, achieving technical success rates of 85-100% with lower perioperative risks than open surgery, according to the American College of Cardiology 1, 2
The American College of Radiology recommends using covered balloon-expandable stents for optimal outcomes in endovascular therapy for atherosclerotic celiac trunk stenosis 2
Systemic anticoagulation serves as adjunct therapy to prevent thrombotic complications, but is not a surrogate for revascularization, as recommended by the Journal of the American College of Radiology 3, 2

For multi-vessel disease, angiography with percutaneous transluminal angioplasty and stent placement is rated as usually appropriate (8/9) for urgent intervention, with priority given to treatment of the SMA, as recommended by the American College of Radiology 1, 2
Surgical bypass or endarterectomy is also appropriate (7/9) as an alternative for multi-vessel disease, according to the American College of Surgeons 1

The American College of Radiology notes that not all patients with imaging evidence of celiac compression are symptomatic, and alternative diagnoses should be considered if symptoms persist after intervention, as celiac compression may be incidental rather than causative 1
