Summary
Anterior spinal artery syndrome can occur after aortic manipulation during cardiac surgery. Early diagnosis using imaging is crucial for at-risk patients, especially those with a history of cardiovascular disease.
Area of Science:
- Cardiovascular Anesthesiology
- Neurological Complications
- Spinal Cord Syndromes
Background:
- Anesthesiology advancements enhance patient safety during cardiac procedures.
- Hemodynamic control and minimizing surgical stimuli are key objectives.
Observation:
- A 70-year-old male with multiple comorbidities underwent aortic manipulation for revascularization.
- Postoperatively, the patient experienced hemodynamic instability and developed flaccid paraplegia below T8.
- Initial CT scan ruled out compressive spinal lesions.
Findings:
- The patient presented with flaccid paraplegia below T8, inconsistent with initial imaging.
- Anterior spinal artery syndrome was suspected as the cause of neurological deficit.
- Echocardiogram revealed no cardiac abnormalities contributing to the paraplegia.
Implications:
- Anterior spinal artery syndrome must be considered in patients undergoing aortic manipulation.
- Proactive prevention strategies are vital for high-risk individuals.
- Advanced imaging like MRI is essential for accurate diagnosis and lesion localization.
