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

The paper discusses whether the outcome of reconstructive surgery can be predicted by using the orthostatic test in Doppler sonography and transcutaneous polarography. A total of 97 patients with severe lower extremity ischemia were studied, of them 87 were operated on. Reconstructive operations on the vessels were performed in 72 patients. There was no relationship between the value of the humero-mallear index of regional systolic pressure as well as TcpO2 and the outcome of an operation. At the same time there was a correlation between the orthostatic rise in regional systolic pressure on the tibial arteries at the ankle-bone and the orthostatic increase in pO2 in the feet and the outcome of a reconstructive operation. The orthostatic rise in pO2 and regional systolic pressure was 8.06 +/- 4.0 and 58.2 +/- 5.43 mm Hg in patients with poor outcomes and inoperable patients, respectively. In good outcomes, these figures were 17.8 +/- 2.14 and 91.3 +/- 3.64 mm Hg (p < 0.05), respectively. The positive outcome of a reconstructive operations was observed in 88.8 = 92.0% patients with an orthostatic rise of pO2 in the feet by more than 20 mm Hg and that at the ankle-bone by more than 90 mm Hg.
