Abstract
The development of diagnostic techniques, surgical and anaesthetic textbooks led to a significant
decrease of surgical complications and mortality during thoracoabdominal aortic procedures.
However, the development of neurological complications (paraplegia and paraparesis) is
a serious problem and the solution is not found till now. Despite the use of various protective
techniques, the risk for ischemic spinal cord, according to large trials, is very high - 3.8-16%.
The main disadvantage of various protective measures, excluding the spinal cord monitoring,
is that the clinical result can be evaluated after postanesthetic recovery, when irreversible injury
has happened. Thus, along with methods of protection, different methods to evaluate the
function of spinal cord during the procedure are studied: electrophysiological neuromonitoring,
biochemical markers of ischemia, direct measure of blood pressure in segmental arteries,
cerebral oxymetry, other experimental and clinical methods.
Clinical and experimental methods of neuromonitoring are described and the results of their
comparison are provided.
