OBJECTIVES: Ischaemic spinal cord injury (SCI) is one of the most serious complications of aortic surgery. Ischaemic SCIs occur due to various aetiologies, and prediction of the risk is difficult. Magnetic resonance imaging (MRI) is useful to detect the details of spinal cord infarction. There are few studies about MRI for evaluating ischaemic SCI after cardiovascular surgery and aortic events. We report 9 cases of postoperative ischaemic SCI and analyse their MRI features.
METHODS: T2-weighted MRI scans of 9 patients who developed ischaemic SCI due to cardiovascular surgery and aortic events between 2012 and 2017 were evaluated.
RESULTS: In all patients, high-intensity areas were observed on T2-weighted magnetic resonance images. The site of infarction was the thoracic spinal cord level (9 cases) and additionally at the lumbar spinal cord level (5 cases). The area of infarction area was categorized based on the arterial territory: anterior spinal artery territory (3 cases), posterior spinal artery territory (2 cases), spinal sulcal artery territory (1 case) and artery of Adamkiewicz territory (3 cases).
CONCLUSIONS: MRI revealed the infarction sites in all cases and the differences in the infarction patterns in each case. MRI could thus be useful for investigating the aetiology of ischaemic SCI following aortic surgeries and events.
