Insights
Endovascular repair using stent-grafts is a feasible and effective treatment for isolated infrarenal aortic dissecting aneurysms. This minimally invasive approach demonstrated successful outcomes with no observed complications in three patients.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Aneurysm Disease
Background:
- Abdominal aortic aneurysms (AAAs) are a significant cause of mortality.
- Dissecting aneurysms present unique management challenges.
- Infrarenal aortic dissecting aneurysms require effective treatment strategies.
Observation:
- Three cases of isolated infrarenal aortic dissecting aneurysms were identified.
- Patients underwent endovascular repair with stent-grafts.
- Thoracic aortic dissection was ruled out via CT angiography.
Findings:
- Stent-graft repair was technically successful in all patients.
- No intraoperative mortality or stent-graft-related complications occurred.
- Patients experienced short hospitalizations with no ICU stay required.
Implications:
- Endovascular repair is a viable option for isolated infrarenal aortic dissecting aneurysms.
- This approach offers a safe and effective alternative to open repair.
- Further research can explore long-term outcomes of this technique.
Objectives:
We report three cases of isolated infrarenal aortic dissecting aneurysms managed with stent-graft.
Materials And Methods:
Three patients, two men and one woman, with a mean age at diagnosis of 69 years were identified. In all cases, chest CT-A did not reveal evidence of thoracic aortic dissection. The mean maximal aneurysm diameter was 6.7+/-1.5 cm (range: 5.5-8 cm). All patients underwent stent-graft repair. Follow-up computed tomographic (CT)-angiography examinations were scheduled 1, 4, and 12 months after the procedure.
Results:
Stent-graft deployment was technically successful in all cases. Intraoperative mortality was not observed. All patients were adequately treated with a bifurcated device. Intensive care unit (ICU) stay was never required. Mean hospitalization was 4.6 days (range: 4-6 days). Mean follow-up was 18 months. No stent-graft-related complications were observed.
Conclusions:
Endovascular repair for isolated infrarenal abdominal aortic dissecting aneurysms is feasible and effective.
