Key result
PCI is linked to rare Brown-Séquard syndrome caused by unilateral spinal cord ischemia.
Why the study?
Iatrogenic spinal cord ischemia after endovascular procedures is rare and unilateral spinal cord ischemia causing Brown-Séquard syndrome has not been previously demonstrated.

This case report highlights the rare occurrence of unilateral spinal cord ischemia (Brown-Séquard syndrome) as an iatrogenic complication following percutaneous coronary intervention.
CONTEXT: Brown-Séquard syndrome is a rare condition caused by injury to one side of the spinal cord. It mostly results from trauma. Ischemic lesions usually do not cause this syndrome because the spinal cord is involved bilaterally. FINDINGS: We reported a case with paralysis of the right lower extremity and hypoesthesia of the left lower extremity after a coronary intervention. His neurological exam and radiological findings match those of Brown-Séquard syndrome. CONCLUSION: Iatrogenic spinal cord ischemia after endovascular procedures are rarely seen. Unilateral spinal cord ischemia was demonstrated firstly with this case.
Temel et al. (2026) conducted a case report in Brown-Séquard syndrome due to spinal cord infarction (n=1). Percutaneous coronary intervention was evaluated on Development of Brown-Séquard syndrome. Percutaneous coronary intervention was followed by unilateral spinal cord ischemia resulting in Brown-Séquard syndrome, presenting with right lower extremity paralysis and left lower extremity hypoesthesia.
