Summary
Nontraumatic spinal cord infarction (SCI) is rare. This study found that patients with less severe initial neurological deficits (higher American Spinal Injury Association scores) had better functional recovery, highlighting prognosis factors.
Area of Science:
- Neurology
- Vascular Neurology
Background:
- Nontraumatic spinal cord infarction (SCI) is a rare and severe neurological condition.
- Understanding its causes and predicting outcomes is crucial for patient management.
Purpose of the Study:
- To describe the clinical features and functional outcomes of patients with nontraumatic SCI.
- To review the etiologies and prognostic factors of SCI based on a literature review and case series.
Main Methods:
- Retrospective case series of eight patients with nontraumatic SCI admitted between 2012 and 2014.
- Literature review of 11 patient series on nontraumatic SCI.
- Assessment of neurological status using the American Spinal Injury Association (ASIA) impairment scale at nadir and follow-up.
Main Results:
- The cohort's mean age was 64 years, with a slight female predominance.
- Identified etiologies included aortic disease (3), fibrocartilaginous embolism (2), anterior spinal artery aneurysm (1), and undetermined (2).
- Nadir ASIA scores were predominantly C/D, correlating with better functional outcomes compared to literature averages (mostly ASIA A/B).
Conclusions:
- Functional outcomes in nontraumatic SCI are strongly linked to initial neurological severity, particularly ASIA scores at nadir.
- Patients with less severe initial deficits (higher ASIA scores) tend to achieve better functional recovery.
- Early identification of prognostic factors is essential for guiding treatment and rehabilitation strategies in SCI.
