【摘要】 目的：应用多普勒超声测定多普勒血流灌注指数（ＤＰＩ）、阻力比（ＲＲ）等血流参数，用以评价其对肝癌术后复发患者的诊断价值。方法：２０例正常对照、３０例原发性肝癌、１５例肝癌术后复发和１５例无复发患者在禁食１２小时后应用多普勒超声测定ＤＰＩ、ＲＲ等血流参数。结果：①无复发组肝总动脉（ＣＨＡ）的检出率显著低于复发组（Ｐ＜０．０５）。②肝癌组及肝癌术后复发组的ＤＰＩ显著高于对照组和无复发组（Ｐ＜０．０１）。③复发组的ＲＲ高于无复发组（Ｐ＜０．０５）。④ＤＰＩ０．２６时，对肝癌术后复发诊断的敏感性、特异性和准确性分别为８５．７％、８８．９％和８７％。结论：肝癌术后复发患者与原发性肝癌的血流动力学变化一样，肝动脉血流量增加，门静脉血流量减少。通过测定ＤＰＩ，有利于复发患者的早期诊断和鉴别诊断。更多还原

【Abstract】 Purpose:To assess the value of the DPI and RR measured with Doppler Ultrasound (DUS) in diagnosing recurrent primary hepatocellular carcinoma after partial hepatectomy.Methods:The DPI,RR and other parameters were measured with DUS in 20 controls,30 patients with PHC,15 patients with postoperative recurrent PHC and 15 without postoperative recurrence of PHC after 12 hours of fasting.Results:①The detection rate of the common hepatic artery in the nonrecurrent group was lower than that of the recurrent guoup (P<0.05).②The DPI of the PHC and recurrent guorps were significantly raised compared with those of the controls and nonrecurrent group (P<0.01).③The RR of the recurrent group was higher than that of the nonrecurrent group (P<0.05).④When DPI0.26 was used to diagnose the postoperative recurrence of PHC,the sensitivity,specificity and accuracy were 85.7%,88.9% and 87%,respectivly.Conclusion:The results suggest that it is useful to measure the DPI in the differential dignosis and earlystage diagnosis of the recurrence of PHC.更多还原
