[The potentials of polarography in predicting the effect of a reconstructive operation in patients with severe ischemia of the lower extremities].

Possibilities to prognose the effect of reconstructive operation on the lower extremity vessels are shown on the basis of transcutaneous of oxygen on the dorsal surface of the foot in complex with ultrasonic Dopplerometry in patients with severe ischemia of lower extremities. Effectiveness of the test with the orthostatic growth of Po is proved. An examination of 60 patients with severe ischemia of lower extremities and 10 patients without pathology of main vessels (control group) was performed. Operations were performed on 48 patients, in 35 of them reconstructive operations were made. No correlation was found between preoperative value of Po and a result of the reconstruction. A correlation was found between the value of the orthostatic growth of Po and outcome of the reconstructive operation. The average growth of Po in the group of patients with a negative outcome of the reconstruction made up 9.93 + 2.78 mm Hg, with a positive outcome it was 14.137 + 2.30 mm Hg (p < 0.05). In patients with malleolus index of the regional systolic pressure > 0.3 with the orthostatic growth of Po > 20 mm Hg the probability of positive prognosis of the reconstruction made up 88.8%.
