Insights
Induced hypotension can cause lumbar spinal cord infarction, particularly affecting the artery of Adamkiewicz. This study examines the spinal cord blood supply and the vulnerability of this critical artery to low blood pressure.
Area of Science:
- Neurology
- Vascular Surgery
- Anatomy
Background:
- Spinal cord infarction is a rare but devastating neurological event.
- The artery of Adamkiewicz is the primary blood supply to the lumbar spinal cord.
- Induced hypotension is a surgical technique that can compromise blood flow.
Abstract:
Four patients developed infarction of the lumbar cord as a result of induced hypotension. All patients showed a lesion in the territory of the artery of Adamkiewicz. The pathophysiology of the blood supply of the spinal cord is discussed, and in particular the anatomy of the artery of Adamkiewicz. The reason why this artery is so vulnerable to hypotension is discussed.
