[Anatomical and physiological assessment of the collateral circulation in experimental femoral artery ligation in venous insufficiency].

Peculiarities of collateral circulation following isolated and combined ligations of the femoral vessels were studied in experiments on 62 dogs through physiologic and anatomic investigation methods. It has been shown that the ligation of the vein prevents the exsanguination of the limb, arising from an injury to the main artery, favours an accelerated anatomic reconstruction of the arterial collaterals, but increases microcirculatory disturbances, aggravates tissue ischemia and disorder of the acid-base balance, which as a whole evidences a detrimental effect of concomitant venous insufficiency upon the process of the restoration of the circulation in the limb.
