[Evaluation of severity of ischemia after injuries of the major arteries of the extremity].

Experiments were conducted in 32 dogs to study the results of rheography, ultrasonic Dopplerometry, electric excitability of muscles, and tissue pH measurement in various periods of ischemia and after restoration of blood flow in the extremities. Clinical follow-up of 226 patients with injuries to the major arteries of an ischemic extremity confirmed the importance of the results of instrumental methods of examination for appraising the severity of ischemia and predicting its outcomes. The author distinguished four degrees of ischemia in injury to the vessels. Combination of clinical findings and the results of special methods of treatment makes it possible to choose the rational surgical tactics in traumas of the arteries of the extremities.
