Spinal artery syndrome following kyphoplasty in the setting of a non-compressive extradural cement extravasation: a case report

Spinal Cord Series and Cases, 2023 · DOI: https://doi.org/10.1038/s41394-023-00574-6 · Published: April 14, 2023

Simple Explanation

A 77-year-old female experienced leg weakness after kyphoplasty due to cement leakage without compressing the spinal cord. Surgery was performed, and post-operative MRI showed spinal artery syndrome, which is a disruption of blood flow to the spinal cord. The patient showed almost complete recovery of neurological function one month after surgery.

Study Duration

6 months

Participants

One 77-year-old female

Evidence Level

Level 4, Case Report

Key Findings

1
The patient developed progressive paraparesis following kyphoplasty with non-compressive extradural cement extravasation.
2
Post-operative MRI confirmed spinal artery syndrome as the cause of the paraparesis.
3
Surgical decompression and cement excision led to near-complete neurological recovery.

Research Summary

This case report describes a rare instance of spinal artery syndrome following kyphoplasty caused by non-compressive cement extravasation. The patient presented with progressive paraparesis, and diagnosis was confirmed with post-operative MRI showing spinal artery syndrome. Surgical intervention led to significant neurological recovery, suggesting that surgery may be indicated even without direct cord compression.

Practical Implications

Consider Spinal Artery Syndrome

In patients with neurological deficits post-kyphoplasty, even without cord compression, spinal artery syndrome should be considered.

Surgical Intervention

If medical management fails to improve deficits in spinal artery syndrome post-kyphoplasty, surgery may be warranted, even without cord compression.

Monitor MAP

Maintain elevated MAP goals post-operatively to ensure adequate spinal cord perfusion.
