Summary
Mid-term results show the AneuRx stentgraft is a feasible option for endovascular aneurysm repair, with few major complications. Continued follow-up is crucial for detecting potential late issues.
Area of Science:
- Vascular Surgery
- Medical Devices
- Endovascular Repair
Background:
- Endovascular Aneurysm Repair (EVAR) offers a less invasive alternative to open surgery for Abdominal Aortic Aneurysm (AAA).
- The AneuRx stentgraft is a self-expandable nitinol device used in EVAR.
Purpose of the Study:
- To evaluate the mid-term clinical outcomes of the AneuRx stentgraft in patients undergoing EVAR.
- To report on the safety and efficacy of the AneuRx device in a single-center experience.
Main Methods:
- A prospective study included 128 patients treated with the AneuRx bifurcated stentgraft between December 1996 and January 2000.
- Seventy-seven patients had a minimum follow-up of 12 months, with data prospectively collected.
Main Results:
- Periprocedural mortality was 5%. Two conversions to open surgery were required.
- Eighteen endoleaks (6 type 1, 8 type 2, 4 type 3) occurred in 15 patients; 76% freedom from endoleak at 2 years.
- Graft migration occurred in 6% of patients, with 90% freedom from migration at 2 years.
Conclusions:
- Endovascular AAA repair using the AneuRx stentgraft is feasible with acceptable mid-term results.
- Close and extensive patient follow-up is essential to manage potential secondary complications.
- Long-term outcomes require further evaluation.
