What is the management approach for a patient with severe stenosis of the celiac trunk (celiac takeoff) and a history of atherosclerosis, presenting with risk factors such as hypertension, diabetes, and hyperlipidemia?

Management of Severe Celiac Trunk Stenosis

For atherosclerotic celiac trunk stenosis in a patient with cardiovascular risk factors, 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. 1

Initial Diagnostic Evaluation

The management approach depends critically on determining the etiology of stenosis—atherosclerotic versus median arcuate ligament (MAL) compression—as this fundamentally changes treatment strategy. 1

Key Imaging Requirements

• CT angiography (CTA) is the initial imaging modality of choice, with 95-100% sensitivity and specificity for detecting mesenteric vascular abnormalities. 1, 2

• Look specifically for:

  • Atherosclerotic calcified plaque at the celiac origin versus "J-shaped" proximal narrowing (suggesting MAL). 1
  • Presence and extent of collateral circulation, particularly pancreaticoduodenal arcades from the superior mesenteric artery (SMA). 1, 3
  • Involvement of other mesenteric vessels (SMA, IMA), as multi-vessel disease significantly impacts treatment decisions. 1

• Mesenteric angiography with lateral projection during both inspiration and expiration should be performed if MAL is suspected, as dynamic worsening on expiration confirms extrinsic compression. 1

Treatment Algorithm Based on Etiology

For Atherosclerotic Celiac Stenosis (Your Patient's Likely Scenario)

Endovascular therapy is the definitive first-line treatment:

• Angioplasty with stent placement achieves 85-100% technical success rates and has significantly lower in-hospital complications compared to surgical approaches (p=0.006). 1, 2
• Use covered balloon-expandable stents for optimal outcomes. 2
• Systemic anticoagulation serves only as adjunct therapy, not monotherapy—it prevents clot propagation but is not a surrogate for revascularization. 4, 2

Surgical bypass or endarterectomy is reserved for:

• Patients unsuitable for endovascular intervention. 1
• Cases where endovascular approach is not technically feasible. 2
• When combined with other planned abdominal surgery. 1

For Median Arcuate Ligament Syndrome (If Applicable)

Surgical release of the MAL is first-line treatment, achieving 84.6% symptomatic relief. 1, 5

Critical distinction: Endovascular stenting alone without surgical ligament release is contraindicated for MAL syndrome due to persistent extrinsic compression causing stent fracture, slippage, or migration. 1, 5

• If residual stenosis >30% persists after MAL release, additional revascularization (stenting or bypass) should be performed. 1, 5
• Combined decompression and revascularization achieves 76% persistent symptom resolution long-term. 5

Multi-Vessel Disease Considerations

If imaging reveals involvement of multiple mesenteric vessels (celiac, SMA, IMA):

• Angiography with percutaneous transluminal angioplasty and stent placement is rated as usually appropriate (8/9) for multi-vessel disease requiring urgent intervention. 1
• Prioritize treatment of the SMA as it provides the most critical blood supply to the intestines. 2
• Surgical bypass or endarterectomy is also appropriate (7/9) as an alternative for multi-vessel disease. 1

Critical Pitfalls to Avoid

Collateral Circulation Management

• Preservation of pancreaticoduodenal arcades is paramount during any intervention, as these represent the primary collateral pathway from the SMA to the celiac territory. 6, 3, 7
• Severe ischemic complications occur in 6.9% of cases, with higher rates (20%) when CAS is discovered intraoperatively without preoperative planning. 7
• The risk of upper abdominal organ ischemia is minimized only if collateral preservation is realized. 7

Aneurysm Risk

• Celiac trunk stenosis creates hemodynamic stress leading to pancreaticoduodenal artery aneurysms in some patients, which carry a 50% mortality rate at rupture regardless of size. 6
• If aneurysms are discovered, they must be treated whenever identified, typically with selective coil embolization while preserving flow to the celiac territory. 6

Asymptomatic Stenosis

• Not all patients with imaging evidence of celiac compression are symptomatic—compression may be a normal finding in up to 20% of the population. 1
• Alternative diagnoses should be considered if symptoms persist after intervention, as celiac compression may be incidental rather than causative. 1

Specific Management for Your Patient Profile

Given the atherosclerotic risk factors (hypertension, diabetes, hyperlipidemia):

• Proceed directly to endovascular angioplasty with stent placement as the definitive intervention. 1, 2
• Initiate anticoagulation as adjunct therapy to prevent thrombotic complications. 4, 2
• Optimize medical management of atherosclerotic risk factors to prevent progression. 2
• Evaluate for concomitant SMA and IMA stenosis, as multi-vessel atherosclerotic disease is common and impacts prognosis. 4, 1
