Comparison of perioperative oxidative stress in endovascular and open repair of abdominal aortic aneurysm

Objective & Hypothesis:To investigate the differences in perioperative oxidative stress (OS) in abdominal aortic aneurysm (AAA) patients treated with either endovascular repair (EVAR) or open repair (OR).

📊

Key Findings & Data:Materials and methods: Twenty patients (11 OR, 9 EVAR) treated for AAA with no known malignant or inflammatory disease and an aneurysm diameter of over 5 cm and no rupture were included in the study.

💡

Conclusion & Impact:More studies are required for a clear-cut conclusion.

Abstract

To investigate the differences in perioperative oxidative stress (OS) in abdominal aortic aneurysm (AAA) patients treated with either endovascular repair (EVAR) or open repair (OR). Materials and methods: Twenty patients (11 OR, 9 EVAR) treated for AAA with no known malignant or inflammatory disease and an aneurysm diameter of over 5 cm and no rupture were included in the study. Blood samples were obtained preoperatively, during aortic occlusion, and 1 h and 24 h after reperfusion. Total antioxidant status (TAS), total oxidative stress (TOS), and malondialdehyde (MDA) levels were measured and oxidative stress index (OSI) was calculated. Results: OSI at 1 h and 24 h after reperfusion was higher in the EVAR group (P = 0.004 and P = 0.002, respectively). TAS levels were higher (P = 0.001, P = 0,029). MDA levels showed no difference (P = 0.291, P = 0.076). TOS levels were lower 24 h after reperfusion in the EVAR group (P = 0.018). Conclusion: Markers of oxidative stress were lower in the EVAR group. This may be associated with advantages of EVAR. More studies are required for a clear-cut conclusion.
