| 目的 采用彩色多普勒血流成像(CDFI)技术检测乙肝后肝硬化球后血流,推断其高动力循环的程度。方法 采用美国Acuson公司生产的Sequoia 512型彩色超声诊断仪,分别测量32例正常成人、102例乙肝后肝硬化患者的肝动脉(HA)、眼动脉(OA)、睫状体后短动脉(PCA)、视网膜中央动脉(CRA)的收缩期峰值流速(PSV)和阻力指数(RI)。结果 ①乙肝后肝硬化各组的HA、OA、PCA、CRA血流参数与正常组相比较:肝功能B、C级组和脾切除术后组的PSV均升高,RI降低;肝功能A级组仅表现为RI降低。②乙肝后肝硬化各组OA、PCA、CRA与HA的RI相关性比较:HA与OA、PCA、CRA的RI相关性较好,相关系数分别为0.88、0.88和0.93。结论 乙肝后肝硬化球后血流变化程度与肝动脉高度一致,表明高动力循环状态既存在于内脏血管,也存在于外周末梢动脉血管,且随肝功能损害程度的加重而明显。 |

| Purpose To detect the characteristic of ocular blood flow in patients with postaphetitic cirrhosis by color Doppler flow imaging (CDFI), to deduce the grade of hyperdynamic circulation. Methods The hemodynamic parameters such as peak systolic velocity (PSV) and resistance index (RI) of hepatic artery (HA), ophthalmic artery (OA), artery (PCA) and central retinal artery (CRA) in 32 normal persons, 102 postaphetitic cirhosis patients were studied by CDFI (USA Sequoia 512). Results ①Contrasted with the normal group, the PSV value of several arteries in group B, group C and the group of subsequence of splenectomy were increased, while RI value were decreased. But in group A, only the RI value decreased. ②A direct relationship was found between RI value of HA to OA, PCA and CRA. It was to say the higher RI value of HA was, the higher RI values of OA, PCA and CRA were. Conclusion The change of the blood flow of ocular vascular was consistent with the HA which showed that the hyperdynamics not only existed in internal organs, but also in end-brush perivascular and would be aggravated with the further damaging of liver function. |
