Key result
In patients undergoing off-pump CABG, there was a statistically significant difference in mean regional cerebral oxygen saturation at the time of partial aortic clamp between patients with right carotid stenosis of 50-69% and those with less than 50% stenosis (p=0.043).
Why the study?
Does preoperative carotid artery stenosis correlate with intraoperative regional cerebral oxygen saturation in patients undergoing off-pump CABG?
Cross-Sectional (n=96)
No
Does preoperative carotid artery stenosis correlate with intraoperative regional cerebral oxygen saturation in patients undergoing off-pump CABG?
Absolute Event Rate: 59.72% vs 53.06%
p-value: p=0.043
In patients undergoing off-pump CABG, carotid artery stenosis of less than 70% does not significantly correlate with regional cerebral oxygen saturation overall, though a significant difference was observed during partial aortic clamping.
No takes yet. Share an insight, caveat, or question.
Should not alter preoperative carotid assessment in off-pump CABG; leaves open impact of moderate stenosis on saturation during clamping.
Heidari et al. (2015) conducted a cross-sectional in Coronary Artery Disease (Candidates for off-pump CABG) (n=96). Carotid artery stenosis (50-69% vs <50%) vs. Carotid artery stenosis <50% was evaluated on Mean regional cerebral oxygen saturation (rSO2) of the right side of the brain at the time of partial aortic clamp (p=0.043). In patients undergoing off-pump CABG, there was a statistically significant difference in mean regional cerebral oxygen saturation at the time of partial aortic clamp between patients with right carotid stenosis of 50-69% and those with less than 50% stenosis (p=0.043).
