title: Peripheral arteries of the extremities in acute ischemia.
abstract: Changes in peripheral arteries of the extremities during acute ischemia were examined in 108 patients with embolism and 18 with arterial injuries. All patients were divided into four degrees of ischemia due to our own original classification. It can be stated that patients with the first degree of ischemia presented patent peripheral arteries. The rest of the patients presented different changes in the peripheral arteries such as thrombus or their patency was failed by the rigidity of the non-striated muscles of the arterial wall or by the pressure of the oedematous muscles. A new factor, decreasing after operation, an inflow of blood to the leg or to the hand, was found. It was an opening of the arteriovenous fistulas at the level of obstruction. The diagnostic value of the different tests for intraoperative assessment of the patency of the peripheral arteries is the discussed, emphasizing the value of the intraoperative arteriography.
