Insights
A modified stent-assisted coil embolization technique successfully treated a large celiac trunk aneurysm. This endograft-assisted approach is a safe and feasible option for complex cases.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Endovascular Techniques
Background:
- Celiac trunk aneurysms are rare but life-threatening vascular lesions.
- Endovascular treatment is preferred due to lower morbidity and mortality rates.
Observation:
- A 67-year-old male patient with a history of aortic aneurysm exclusion presented with a 50-mm celiac trunk aneurysm.
- Anatomical challenges precluded standard endograft repair, necessitating a modified technique.
Findings:
- A novel endograft-assisted coil embolization, adapted from intracranial aneurysm treatment, was successfully performed.
- This technique allowed selective sac embolization while maintaining flow to the splenic artery and indirect flow to the hepatic artery.
Implications:
- Endograft-assisted coil embolization is a feasible and safe alternative for complex celiac trunk aneurysms.
- This modified technique expands endovascular treatment options for rare and challenging vascular pathologies.
Background:
Celiac trunk aneurysms are rare but potential life-threatening lesions. Endovascular techniques are more often used for their treatment because of low rates of morbidity and mortality.
Case Report:
We describe a modification of stent-assisted coil embolization technique more commonly used in the treatment of intracranial aneurysm, to exclude a 50-mm diameter celiac trunk aneurysm. The patient was a 67-year-old man who had a previous exclusion of a symptomatic aortic aneurysm, with occlusion of the inferior mesenteric and both hypogastric arteries. Anatomic features of the celiac trunk aneurysm and its branches do not allow treatment with a straight endograft or maintain direct flow to the hepatic artery. We then performed an endograft-assisted coil embolization of the aneurysm, with a straight flow line to the splenic artery.
Conclusion:
Endograft-assisted coil embolization is a feasible and safe technique to allow selective embolization of the sac and the presence of direct flow to the splenic artery and indirect flow to the hepatic artery.
