Summary
Endovascular aneurysm repair (EVAR) offers an alternative to open abdominal aortic aneurysm (AAA) repair, potentially improving operative mortality. While short-term benefits are shown, long-term efficacy data for EVAR are still needed.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Technology Assessment
Background:
- Conventional abdominal aortic aneurysm (AAA) repair has shown stagnant operative mortality rates over the past 20 years.
- Endovascular aneurysm repair (EVAR) emerged in 1991 as a less invasive alternative to open AAA repair.
- EVAR presents a potential strategy to reduce the operative mortality associated with AAA treatment.
Purpose of the Study:
- To provide a comprehensive overview of endovascular aneurysm repair (EVAR).
- To discuss the potential benefits of EVAR in treating abdominal aortic aneurysms.
- To critically evaluate the current limitations and challenges associated with the EVAR technique.
Main Methods:
- Review of existing literature on endovascular aneurysm repair (EVAR).
- Analysis of data from recent large randomized trials comparing EVAR and open AAA repair.
- Synthesis of information regarding the short, medium, and long-term outcomes of EVAR.
Main Results:
- Two recent randomized trials indicate short and medium-term advantages of EVAR over open abdominal aortic aneurysm (AAA) repair.
- Operative mortality for conventional AAA repair has seen minimal improvement over two decades.
- Long-term efficacy data for endovascular aneurysm repair (EVAR) are still limited and require further investigation.
Conclusions:
- EVAR represents a significant advancement in the treatment of abdominal aortic aneurysms (AAAs).
- While offering proven short-to-medium term benefits, the long-term outcomes and durability of EVAR require continued study.
- Further research is necessary to fully understand the limitations and optimize the application of EVAR.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
