[Regulation of blood circulation in the extremities in intermittent claudication].
The study was aimed to investigate the characteristics of the limb circulation in patients suffering from intermittent claudication. The study group consisted of 71 patients with intermittent claudication. As control served the data of 60 patients with intact peripheral circulation and 24 patients suffering from rest pain, too. The limb blood flow was measured by the venous isotope dye-dilution method.


RESULTS
1. The limb blood flow will be diminished in intermittent claudication already in resting state. The decrease of the limb blood flow is more expressed in severe claudication (with short claudication distance). 2. The pathological condition of the limb circulation in intermittent claudication can be characterized by the elevation of the limb vascular resistance. 3. The O2 consumption of the limb tissues will decrease in intermittent claudication. The data of the study are indicating that the regulation of the limb circulation will pathologically be changed in claudication. The reserves of the peripheral circulation are diminished and the insufficiency of the limb circulation will be manifested on walking.
