Key result
Indirect surveillance of the spinal cord by near-infrared spectroscopy (NIRS) is a tempting noninvasive option to detect potential spinal cord ischemia during aortic aneurysm repair.
Why the study?
Does near-infrared spectroscopy of paraspinous muscles detect potential spinal cord ischemia in patients undergoing thoracic/thoracoabdominal aortic aneurysm repair?
Does near-infrared spectroscopy of paraspinous muscles detect potential spinal cord ischemia in patients undergoing thoracic/thoracoabdominal aortic aneurysm repair?
NIRS of paraspinous muscles offers a promising noninvasive method for real-time indirect neuromonitoring of the spinal cord during complex aortic surgery to prevent paraplegia.
May enable real-time CN monitoring to detect spinal cord ischemia in TAA/A repair; leaves open outcome impact pending controlled trials.
Paraplegia remains the most devastating complication of open and endovascular thoracic/thoracoabdominal aortic aneurysm (TAA/A) repair. However, the assessment of currently available neuromonitoring modalities remains challenging and difficult to interpret. Near-infrared spectroscopy (NIRS) has been introduced as a strategy for noninvasive, real-time monitoring of the paraspinous collateral network (CN) to detect potential spinal cord ischemia at our institution. Prior to TAA/A repair, a cerebrospinal fluid catheter is placed and four NIRS optodes are bilaterally positioned on the patient's back to transcutaneously monitor regional muscle oxygenation at the thoracic and lumbar levels. Indirect surveillance of the spinal cord by NIRS seems to be a tempting option with increasing evidence supporting the CN concept.
