THE ELECTRONEUROGRAPHIC EXPLORATION IN THE NEUROPATHIES ASSOCIATED WITH THE OBLITERATIVE CHRONIC ARTERIOPATHIES OF THE LOWER LIMBS
Abstract:
This article aims to set a electroneurographic investigation grid for patients with ischemic pathology of the lower limbs and to assess the involvement degree of the peripheral nervous system at this patients. The electrophysiological investigation of 47 patients with chronic obliterative arteriopathy of the lower limbs showed that the decrease in CMAP amplitude is much more common in comparison with the decease of VCM, suggesting a predominantly axonal impairment of the motor nerves. Both the motor action potential amplitude as well as the motor conduction velocity decrease differently on the studied nerves, fact that suggests the presence of multiplex mononeuropathy. A significant proportion of studied nerves are normal, sustaining the predominantly inhomogeneous effect on the peripheral nerves in ischemic neuropathy. With regard to sensory nerve damage, decreasing the potential amplitude is much more frequently encountered, in comparison with the decrease of the sensitive conduction velocity, suggesting the predominantly axonal impairing of the studied sensory nerves.
