脉动色素浓度测定法检测有效肝脏血流量对肝病患者的临床意义

目的 介绍一种肝储备功能与肝脏有效血流量(effective hepatic blood flow,EHBF)的检测方法 ,探讨其临床意义.方法 采用脉动色素浓度测定法(pulse dye densitometry,PDD)和传统的分光光度仪比色法同时检测92例患者吲哚菁绿(indocyanine green,ICG)15 min滞留率(ICGR_(15)),分析榆测结果 的相关性;采用PDD法检测1 181例肝癌、85例门脉高压和120例肝血管瘤患者ICGR_(15)、ICG清除率(K)、全身血容量(BV)、心输出量(CO)及EHBF.结果 PDD测定法检测的ICGR15与分光光度仪比色法的测定结果 显著相关(Y=0.789x+2.109,r=0.945,P<0.01).肝癌和门脉高压患者EHBb、较肝血管瘤组显著降低,ICGR_(15)和CO显著升高.ICGR15值小于10%的肝癌患者EHBF平均为1.233 L/min,EHBF随着ICGR_(15)的升高显著降低;60岁以上肝癌患者K值、CO和EHBF较60岁以下组均显著降低.结论 脉动色素浓度测定法具有无创、实时、便捷等优点,检测的各项数据对评估肝储备功能和EHBF,把握手术方式和范围有一定的参考价值.

Clinical significance of pulse dye densitometry in effective hepatic blood flow detection

Objective To introduce a new method for measuring hepatic reserve function and effective hepatic blood flow (EHBF),and to assess its clinical significance. Methods The correlation between indocyanine green retention rate at 15 min (ICGR15) measured by pulse dye densitometry (PDD) and spectrophotometry was analyzed in 92 patients. 1181 patients with hepatocellular carcinoma (HCC),85 patients with portal hypertension and 120 patients with hepatic hemangioma were enrolled in this study. ICGR15,plasma dye clear...
