Implication

May aid post-aortic ischemia prognostication; leaves open prospective validation before practice change.

Key Points

Characterize thoracic spinal cord MRI findings and evaluate their relationship to clinical outcomes in patients developing ischemia after thoracoabdominal aortic aneurysm surgery.
Evaluated thoracic spinal cord MR images in 24 patients who developed signs and symptoms of spinal cord ischemia or infarction following thoracoabdominal aortic aneurysm repair.
Categorized ischemic signal abnormalities into four distinct patterns (types A through D) according to the extent of gray matter and surrounding white matter involvement.
Detected four distinct ischemic signal patterns (types A–D) localized predominantly within the anterior spinal artery territory.
Observed a strong qualitative correlation between the anatomic distribution of cord signal abnormalities, initial neurologic deficit severity, and final clinical outcome.

What are the MR imaging findings in patients with spinal cord ischemia following thoracoabdominal aortic aneurysm resection?

Population

24 patients who developed signs and symptoms of spinal cord ischemia or infarction following surgery for a thoracoabdominal aortic aneurysm

Intervention

MR imaging of the thoracic spinal cord

Outcome

Patterns of signal abnormalities in the distribution of the anterior spinal arterysurrogate

MR imaging is an effective method for diagnosing and characterizing spinal cord ischemia following thoracoabdominal aortic aneurysm surgery, with imaging patterns correlating with clinical severity.
