The relationship between coronary collateral circulation and palmar circulation

Coronary collateral vessels, provide link between coronary arteries, decreased both mortality and morbidity in patients with myocardial infarction. Palmar collateral circulation locates between ulnar and radial arteries, and its adequacy can be evaluated by noninvasive tests. We aimed in this study to investigate relationship between coronary collateral circulation and palmar collateral circulation. 96 patient, detected in coronary arteries at least 70% stenosis, were included the study. Coronary collateral circulation was evaluated according to rentrop classification as adequate and inadequate collateral circulation. Hand circulations of the patients were evaluated with Allen Test and Modified Allen Test. Incomplete palmar arch were detected in patients with adequate and inadequate coronary collateral circulation 22% and 29%, respectively. There was no significant different between two groups according to presence of incomplete or complete palmar circulation. In our study, we demonstrated that there was no relationship between coronary collateral circulation and palmar collateral circulation.
