[Electrophysiological evaluation of peripheral nerves in ischemic lower limbs].

The study concerned electrophysiological parameters during stimulation of peroneal, tibial, sural and femoral nerves of patients with ischemia of lower limbs. The disease was clinically verified and confirmed on the basis of an ankle-brachial index (ABI). Peripheral nerves injuries caused by other reasons have been excluded from the research. For statistical evaluation of the material, groups of 86 chronic ischemic limbs (ABI < 0.91) and 57 healthy ones (ABI > 0.99) were created. All observation allowed to recognize an axonal-demyelization neuropathy, with strong axonal element. Changes concerned mainly long nerves. Coexistence of spinal roots damage was often (75.4%) noticeable. The correlation between degree of ischemia (ABI) and studied parameters has not been noticed. We described 5 cases of acute ischemia. There was no significant improvement after surgical or conservative therapy.
