Abstract

Objective: We report a case of spinal cord infarction following mechanical thrombectomy for acute basilar artery occlusion, and describe the pathophysiological mechanism of spinal cord infarction and its possible prevention.

Case Presentation: A 70-year-old man developed dysarthria and left-sided sensory impairment and was then diagnosed with acute basilar artery occlusion. Mechanical thrombectomy was performed using a 6-Fr guiding sheath via the left vertebral artery (VA). Complete recanalization was achieved within 1.5 hours. However, toward the end of the procedure, the guiding sheath was wedged in the distal portion of the VA. Postoperatively, left-sided flaccid paralysis and right-sided sensory deficit were observed. Cervical magnetic resonance imaging (MRI) demonstrated an acute spinal cord infarction on the left side, at the level of C3. The cause of infarction was suspected to be the wedging of the guiding sheath during the procedure.

Conclusion: Spinal cord infarction is a rare but serious complication of mechanical thrombectomy for acute basilar artery occlusion. The selection of appropriate procedure, device, and safe access route are essential for the success of a mechanical thrombectomy for acute basilar artery occlusion.
