Abstract:
An infected aortic aneurysm (IAA) is a rare but potentially life-threatening pathology characterized by rapid growth and a substantial risk of rupture compared to non-infected aneurysms. Reports on the endovscular treatment of infected paravisceral aneurysms are limited in the literature. This article describes our experience with endovascular repair of IAAs involving the visceral arteries and includes a literature review. We present two cases of symptomatic IAAs located at the celiac trunk ostium in high-risk surgical patients. Both cases were successfully treated with the parallel stent grafting (PG) technique in combination with prolonged antibiotic therapy. A bibliographic review of the endovascular treatment of IAAs was also conducted. Complex endovascular repair of paravisceral IAAs using a combination of a thoracic aortic stent graft and PG, together with prolonged antibiotic therapy, appears to be a reasonable treatment option with promising short- and medium-term results.
Insights
Infected aortic aneurysms (IAAs) pose a high rupture risk. Endovascular repair using parallel stent grafting and antibiotics offers a viable treatment option for these complex cases.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Infectious Diseases
Background:
- Infected aortic aneurysms (IAAs) are rare, aggressive vascular pathologies with high rupture rates.
- Endovascular treatment options for infected paravisceral aneurysms are not well-documented.
- Surgical intervention for IAAs is associated with significant morbidity and mortality, especially in high-risk patients.
Purpose of the Study:
- To describe the experience with endovascular repair of infected aortic aneurysms involving visceral arteries.
- To evaluate the efficacy and safety of the parallel stent grafting (PG) technique in treating IAAs.
- To review the current literature on endovascular management of IAAs.
Main Methods:
- Presentation of two cases of symptomatic IAAs at the celiac trunk ostium in high-risk surgical patients.
- Successful endovascular repair utilizing the parallel stent grafting (PG) technique.
- Combination of endovascular repair with prolonged antibiotic therapy.
- Comprehensive literature review on endovascular treatment of IAAs.
Main Results:
- Both patients with symptomatic IAAs were successfully treated with the PG technique.
- The endovascular approach, combined with prolonged antibiotics, demonstrated promising short- and medium-term outcomes.
- The technique involved a combination of a thoracic aortic stent graft and PG.
Conclusions:
- Complex endovascular repair of paravisceral IAAs using a combination of thoracic aortic stent graft and PG is a feasible treatment option.
- This approach, coupled with prolonged antibiotic therapy, appears to be a reasonable strategy for high-risk patients.
- The study suggests promising short- and medium-term results for this endovascular management of IAAs.
