Insights
Endovascular stent repair effectively treats celiac arterial aneurysms (CAA) with a 100% success rate and no complications. This minimally invasive procedure offers a safe and lasting solution for patients with this condition.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Devices
Background:
- Celiac arterial aneurysms (CAA) are rare but can lead to serious complications.
- Traditional surgical repair of CAA carries significant risks.
- Endovascular techniques offer a less invasive alternative for treating vascular pathologies.
Purpose of the Study:
- To evaluate the safety and clinical effectiveness of endovascular stent repair for celiac arterial aneurysms (CAA).
- To assess technical success rates, complications, and long-term outcomes of this minimally invasive approach.
Main Methods:
- A retrospective analysis of 11 patients who underwent endovascular stent repair for CAA between January 2015 and December 2018.
- Utilized covered stents to occlude the aneurysm neck.
- Follow-up included clinical assessment and imaging at regular intervals post-procedure.
Main Results:
- Achieved 100% technical success rate with no intraoperative or immediate post-procedural complications.
- All patients remained free of aneurysm rupture and endoleaks during a mean follow-up of 22.4 months.
- Demonstrated 100% stent patency and no instances of splenic, hepatic, or bowel infarction.
Conclusions:
- Endovascular stent repair is a safe, simple, and highly effective treatment for celiac arterial aneurysms (CAA).
- This minimally invasive method provides excellent long-term outcomes and avoids major complications associated with open surgery.
Abstract:
The aim of this study was to evaluate the safety and clinical effectiveness of endovascular stent repair of celiac arterial aneurysm (CAA).From January 2015 to December 2018, 11 patients (7 males, 4 females with a mean age of 52.2 ± 7.9 years) underwent endovascular stent repair of CAA in our center. A covered stent was used to occlude the CAA neck. Follow-up was performed 2 weeks and 1, 3, 6, and 12 months following surgery and yearly thereafter. Rates of technical success, treatment-related complications, and long-term outcome were analyzed.Each patient was placed with 1 stent for repair of CAA. Stent was placed in the celiac and common hepatic arteries for 10 patients and was placed in the celiac artery for 1 patient. The duration of the procedure ranged from 50 to 75 minutes (mean 63.2 ± 7.2 minutes). The rate of technical success of the endovascular stent repair was 100%. No patient experienced CAA rupture or instant endoleak during or after stent insertion. Abdominal pain was relieved progressively after stent insertion. All patients were followed-up for 6 to 48 months (mean 22.4 ± 10.8 months). All patients were alive during the follow-up. No endoleaks were experienced during follow-up with 100% stent patency rate. No patient suffered splenic, hepatic, or bowel infarction during follow-up.Endovascular stent repair is a safe, simple, and effective treatment for patients with CAA.
