Celiac trunk coverage in endovascular aneurysm repair
1Department of Radiology, Södersjukhuset, Stockholm, Sweden.
Summary
Covering the coeliac trunk during endovascular aneurysm repair may be safe, even without symptoms of intestinal ischemia. Preoperative angiography is recommended to assess collateral flow from the superior mesenteric artery.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aneurysm Treatment
Background:
- Endografting is a common treatment for aneurysms.
- Obstruction of the coeliac trunk can occur during endovascular aneurysm repair.
- Assessing the risks of coeliac trunk coverage is important.
Purpose of the Study:
- To examine the risks associated with coeliac trunk obstruction during endovascular aneurysm repair.
- To evaluate the safety and outcomes of intentional coeliac trunk coverage.
Main Methods:
- Retrospective study of 120 patients treated with endografting for aneurysmal disease.
- Subgroup analysis of 9 patients with coeliac trunk coverage.
- Preoperative angiography to assess collateral flow from the superior mesenteric artery.
Main Results:
- No severe clinical events or intestinal ischemia were observed in patients with coeliac trunk coverage.
- Three patients experienced a transient increase in liver enzymes.
- Collateral flow assessment predicted the risk of ischemia.
Conclusions:
- Coeliac trunk coverage can be a viable option when the landing zone is inadequate for endografting.
- Preoperative angiography is recommended to evaluate collateral circulation.
- This approach may be considered when surgical alternatives are limited.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
