Correlation Between Intraoperative Near-infrared Spectroscopy Values and Neurologic Outcomes in Patients Undergoing Total Aortic Arch Replacement Using the Frozen Elephant Trunk Technique
Authors' conclusion
NIRS is a reliable tool to monitor intraoperative frontal lobe cerebral oxygen saturation. However, its use to predict postoperative stroke remains limited.
Study context
- Population
- Patients undergoing total aortic arch replacement using the frozen elephant trunk (FET) technique for acute and chronic aortic pathologies, with complete near-infrared spectroscopy (NIRS) data at all predefined time points, 2013–2023of 427 treated with FET
- Participants
- 166 patients
- Exposure
- Intraoperative NIRS values in patients with vs without stroke after FET
- Stroken = 23
- Outcome
- Regional cerebral oxygenation (NIRS) by stroke status
Methodological detailssingle-centre registry, two-way repeated-measures analysis of variance
- Single-centre registry
- Two-way repeated-measures analysis of variance
Main finding
As reported in the abstract
- Interaction time × stroke not significant in any analysis
- p > 0.05
Observational data: associations, not effects.
Further findings
In-hospital mortality · significantly higher with stroke
P = 0.037
- Stroke incidence
- 13.9% · 23
