Summary
Endovascular abdominal aortic aneurysm (AAA) repair offers better respiratory function and less pain relief needs compared to traditional surgery. This minimally invasive approach improves patient recovery after AAA treatment.
Area of Science:
- Vascular Surgery
- Minimally Invasive Procedures
- Patient Outcomes
Background:
- Conventional surgery for abdominal aortic aneurysm (AAA) involves an abdominal incision, potentially leading to respiratory complications and increased pain.
- Endovascular aneurysm repair (EVAR) is a less invasive alternative that avoids a large incision.
Purpose of the Study:
- To compare respiratory function and analgesic requirements between endovascular AAA repair and conventional open surgery.
- To evaluate the impact of surgical approach on postoperative recovery.
Main Methods:
- A comparative study involving 22 age-matched patients undergoing AAA repair under general anesthesia.
- Twelve patients received endovascular aneurysm repair (EVAR), and 10 underwent conventional surgery; one EVAR patient required conversion to open repair.
Main Results:
- The EVAR group had significantly shorter durations of postoperative artificial ventilation (6 vs. 21 hours) and lower patient-controlled analgesia (PCA) morphine consumption (41 vs. 133 mg).
- EVAR patients demonstrated significantly better forced expiratory volume and forced vital capacity at 3 and 5 days postoperatively compared to the conventional group.
Conclusions:
- Endovascular AAA repair significantly reduces perioperative analgesic requirements.
- EVAR attenuates the respiratory dysfunction commonly associated with conventional open AAA surgery, leading to improved pulmonary function post-procedure.
