Differences between immediate and late onset of spinal cord ischemia after open and endovascular aortic interventions.

Spinal cord ischemia remains the most impressive and colliding complication following open surgical and endovascular aortic procedures. Paraparesis and paraplegia are devastating, having a major invalidating impact on the patient's life. Also for the surgeon and the entire team this dramatic adverse event causes a significant concussion. Surgeons faced this problem in practice in the 1950s when this surgery started being applied. Even A. Carrel in 1910 said, "The main danger of the aortic operation does not come from the heart or from the aorta itself, but from the central nervous system". As the number of these surgeries grew, some were followed by the spinal cord ischemia. Now, in 21st century, problem of spinal cord ischemia still exists. By understanding the reasons of its development we shall be able to find more useful methods for prevention as well as for the treatment. The aim of this article was to search what is behind this dreadful complication, explaining different mechanisms which take part in its development during endovascular and open surgical treatment.
