Neurological Deficit From a Purely Vascular Etiology After Unilateral Vessel Ligation During Anterior Thoracolumbar Fusion of the Spine

Abstract

Neurologic deficit after anterior exposure to the thoracolumbar spine occurred in 0.75% of patients in this study exclusively from unilateral left-sided ligation of the T10-T12 segmental vessels. Both patients had common risks of prior kyphosis correction, revision surgery and left-sided approach.
