Endovascular repair of abdominal aortic aneurysm reduces intraoperative cortisol and perioperative morbidity.

概要
BACKGROUND
The release of catabolic stress hormones because of surgical trauma leads to a breakdown of fats, proteins, and carbohydrate stores and interference with immune function. This can delay wound healing and may increase the risk of systemic inflammatory response syndrome (SIRS)/sepsis and postoperative complications. Minimally invasive surgery can attenuate this response. Our purpose was (1) to compare neuroendocrine responses in patients undergoing open abdominal aneurysm repair with those in patients undergoing endovascular aneurysm repair (EVAR), (2) to compare the incidence of SIRS/sepsis and all complications in these two groups, and (3) to look at the relationship between procedure type, neuroendocrine response, and incidence of SIRS/sepsis and complications.
METHODS
Forty-six patients who underwent open repair and 19 who underwent EVAR were studied. A baseline (T1) 24-hour urine save was undertaken in the week before admission, and a second 24-hour save (T2) commenced at anesthetic induction to measure cortisol and catecholamines. The incidences of SIRS/sepsis and complications were recorded.
RESULTS

CONCLUSIONS
An attenuated glucocorticoid surge characterizes the reduced stress response experienced by patients undergoing EVAR compared with open abdominal aortic aneurysm repair. A reduction in the occurrence of SIRS is a feature of a more favorable postoperative course after an endovascular approach.
