[Compensation of disorders of coronary circulation by means of collaterals (according to coronarographic data].
On the basis of an analysis of about 1000 coronary angiogrammes it is established that collaterals develop in stenosis of the coronary arteries in 52.3% of the patients surviving myocardial infarction, and in 20% of those free of myocardial infarction. Coronary angiogrammes of 100 patients with coronary collaterals were examined. Twenty different ways of collateral circulation were revealed. Certain regularities were noted in the development of collaterals depending on the lesions of different coronaries or combined lesions of several arteries. Intersystemic collaterals are most typical for the occlusions of the anterior interventricular branch. In cases of occlusions of the right coronary artery either intersystemic, or intrasystemic collaterals develop, depending on the localization of the occlusion. A study of the collaterals in cases of multiple coronary lesions has demonstrated that under such conditions a complicated system of anastomoses develops, and the flow in them is multidirectional.
