Abstract
The Risk of Spinal Cord Ischemia in ThoracoLumbar Spine Surgery: Attempt to Quantify Predictive Factor
Highlights
The anterior spinal network is a major vascular system irrigating more than 3⁄4 of the spinal cord
It seems to be difficult to assess the risk of paraplegia during thoracolumbar spine surgery or to predict the neurological impact of an arterial sacrifice of the anterior spinal artery system
Focusing on spine thoracic vascularization, an area devoided of artery feedings towards the second and the third thoracic segments (T2-T3) is well identified as a high risk of spinal ischemia [1214]
Summary
The anterior spinal network is a major vascular system irrigating more than 3⁄4 of the spinal cord. It seems to be difficult to assess the risk of paraplegia during thoracolumbar spine surgery or to predict the neurological impact of an arterial sacrifice of the anterior spinal artery system. The origin of AKA is variable, it arises between the 9th to the 12th intercostal artery in 75% of cases or between the 5th to the 8th intercostal artery in 15% of cases or towards the first or second lumbar artery in 10% of cases It penetrates into the spinal canal in 75% of cases accompanied by one of four spinal nerves T9, T10, T11 or T12; in 10% of cases with L1 or L2; in 15% of cases with T5, T6, T7 and T8 [3,4].
