冠状动脉内压力导丝是评价侧支循环灌注功能的主要方法,荷兰学者Vries等研究发现,冠状动脉造影时侧支循环的Rentrop’s分级可以预测侧支循环的灌注功能。该研究入选89例计划接受PCI治疗的稳定型冠心病患者。使用Rentrop’s分级评价冠状动脉造影时侧支循环的血流; Coronary intra-abdominal pressure guide wire is the main method to evaluate the function of collateral circulation perfusion. According to the study by Dutch scholar Vries et al, Rentrop’s classification of collateral circulation can predict the perfusion function of collateral circulation during coronary angiography. The study enrolled 89 stable coronary heart disease patients scheduled for PCI. Rentrop’s grading was used to assess collateral flow during coronary angiography;
