[Functional prognosis of paraplegia due to cord ischemia: a retrospective study of 23 patients].
The functional prognosis of spinal cord infarct is not well known, complicating care of patients suffering from ischemic paraplegia. The aim of this study was to evaluate the clinical and functional outcome of patients with spinal cord infarct treated in rehabilitation centers in order to identify factors influencing functional outcome. We studied cases of non-trauma-related paraplegia treated between 1992 and 1999. Spinal compression and infectious and inflammatory myelopathy were excluded. Age, gender, cardiovascular risk factors, initial and final clinical findings according to the American Spinal Injury Association (ASIA/IMSOP) criteria, MRI findings, and initial urodynamic findings were analyzed. Two groups were identified regarding extension of the spinal cord infarct to the cone or not. Assessment of functional outcome was based on the Frankel classification, ambulatory ability, wheelchair use, and bladder control. Cases of spinal cord infarct were then classified according to extension to the cone or not, determined on the basis of initial clinical, MRI, and urodynamic findings. Twenty-three patients (19 males and 4 females) were selected for analysis. Mean age was 54 years, with no mortality during the follow-up period. At discharge, the group of nine patients whose infarct had not extended to the medullary cone had a significantly better motor recovery using the ASIA motor score (p<0.01). Patients whose infarct did not extend to the cone used wheelchairs less often, were more often in Frankel class D (p<0.05), and had normal bladder control more often (p<0.05) than patients whose infarct extended to the cone. Lack of extension to the medullary cone appeared to be a factor predictive of better functional outcome.
