Management of Celiac Artery Disease
For symptomatic celiac artery stenosis, the treatment approach depends on etiology: surgical release of the median arcuate ligament is first-line for median arcuate ligament syndrome (84.6% symptomatic relief), while endovascular angioplasty with stent placement is first-line for atherosclerotic disease (85-100% technical success). 1
Initial Diagnostic Workup
CT angiography is the initial imaging modality of choice to evaluate:
- Proximal celiac artery narrowing with "J-shaped" configuration (suggests median arcuate ligament compression) 1
- Atherosclerotic changes with calcification 1
- Presence and extent of collateral circulation 1
For suspected median arcuate ligament syndrome, mesenteric angiography in lateral projection during both inspiration and expiration demonstrates dynamic worsening of stenosis on expiration, which is pathognomonic for this condition 1, 2
Management Algorithm Based on Clinical Presentation
Asymptomatic Celiac Artery Stenosis
Observation with supportive measures only is recommended for asymptomatic patients, as celiac artery compression is present in approximately 20% of the general population and is often a normal anatomic variant 2
Do not intervene based on imaging findings alone - compression may be incidental rather than pathologic 2
Symptomatic Celiac Artery Stenosis
Classic symptoms warranting intervention include:
- Postprandial abdominal pain occurring 30-60 minutes after meals 2
- Weight loss (particularly ≥20 pounds) 2
- Food avoidance due to pain (sitophobia) 2
- Nausea and vomiting worsening after meals 1
Treatment Based on Etiology
Median Arcuate Ligament Syndrome
Surgical release of the median arcuate ligament is first-line treatment, achieving symptomatic relief in 84.6% of patients 1
Additional revascularization should be considered if residual stenosis exceeds 30% after ligament release, with options including:
Predictors of successful surgical outcomes include:
- Postprandial pain pattern (81% cure rate) 2
- Age 40-60 years (77% cure rate) 2
- Weight loss ≥20 pounds (67% cure rate) 2
Atherosclerotic Celiac Stenosis
Endovascular therapy with angioplasty and stent placement is first-line treatment, with technical success rates of 85-100% and lower perioperative risks compared to open surgery 1, 3
Surgical bypass or endarterectomy is appropriate (rating 7/9) but typically reserved for:
- Patients unsuitable for endovascular intervention 1
- Multi-vessel disease requiring urgent intervention 1
- When combined with other abdominal surgery 1
Multi-Vessel Disease Requiring Urgent Intervention
Angiography with percutaneous transluminal angioplasty and stent placement is usually appropriate (rating 8/9) for urgent multi-vessel disease 1
Systemic anticoagulation alone (rating 5/9) may be complementary but should not be sole therapy 1, 2
Special Clinical Scenarios
Celiac Artery Aneurysms
Elective repair should be considered in good-risk patients with aneurysms greater than 2 cm, as rupture does occur despite rarity 4
Prosthetic grafts are the conduit of choice for noninfected aneurysms, with excellent long-term results 4
Spontaneous Isolated Celiac Artery Dissection
Most patients can be treated conservatively first with strict blood pressure control, antithrombotic therapy, and intensive surveillance 5, 6
For patients with aneurysmal dilatation (≥12.5 mm diameter) or failed conservative treatment, endovascular stent grafts can be used without affecting branch blood supply 5
Critical Pitfalls to Avoid
Never perform endovascular intervention alone for median arcuate ligament syndrome without surgical release - this leads to poor outcomes due to persistent extrinsic compression, chronic vessel wall changes, and risk of stent fracture or migration 1, 2
Do not rely on systemic anticoagulation for median arcuate ligament compression without evidence of thrombosis - limited data supports this approach 1, 2
Consider alternative diagnoses if symptoms persist after intervention - celiac compression may be incidental rather than causative in up to 20% of cases 1
Recognize that collateral circulation through pancreaticoduodenal arcades from the superior mesenteric artery often prevents clinically significant ischemia despite severe celiac stenosis/occlusion 7
