摘要
目的:探讨肝硬化合并不同病变对门静脉成像延迟时间的影响。方法:搜集符合肝硬化诊断标准的53例患者,将53例病例以有无脾肿大、腹水、静脉曲张各分为两组,即脾正常组(18例)和脾肿大组(35例)、有腹水组(28例)和无腹水组(25例)、有静脉曲张组(39例)和无静脉曲张组(14例)。采用Smart Prep技术监测门静脉主干CT值,同时在工作站上测得同一层面门静脉主干、肝实质的CT值,计算两者差值(P-L差),并绘制时间-密度曲线。结果:脾肿大组、脾正常组门静脉达峰时间分别为(48.2±3.6)s、(42.3±2.8)s,差异有统计学意义(P<0.05);P-L值分别为(70.72±7.40)HU、(74.15±6.50)HU,差异无统计学意义(P>0.05)。有腹水组、无腹水组门静脉达峰时间分别为(42.4±3.1)s、(41.3±2.0)s,差异无统计学意义(P>0.05);P-L值分别为(73.01±10.00)HU、(74.15±8.20)HU,差异无统计学意义(P>0.05)。静脉曲张组、无静脉曲张组门静脉达峰时间分别为(61.2±5.6)s、(40.1±2.1)s,差异有统计学意义(P<0.05);P-L值分别为(41.92±6.80)HU、(71.58±4.90)HU,差异有统计学意义(P<0.05)。结论:肝硬化合并不同病变对门静脉的延迟时间各不同,需区别对待,了解不同病变对肝硬化延迟时间的影响能更好地显示门静脉血管成像。
Objective：To discuss the impact of hepatocirrhosis with various accopamied pathological changes on the delay time of portal vein imaging. Methods： 53 patients with hepatocrirhosis were selected for the study,which were further divided into six groups by whether with or without splenomegaly;ascites and varicosis,including with splenomegaly （35 ca ses）,with no splenomegaly （18 cases）,with ascites （28 cases）.with no ascites （25 cases）, with varicosis （39 cases） and with no varicosis （14 cases）. Smart Prep technique was employed to monitor the CT value of main portal vein （MPV）. In addition ,CT values o{ MPV and liver parenchyma at the same slice were measured on workstation. The difference of the two （＂P-h＂ value） was calculated and the time-density curves were plotted. Results：The peak time of contrast arriving MPV was （ 48.2 ± 3.6 ） s in the splenomegaly group, （42.3 ± 2.8） s in the group with no splenomegaly, with significant statistic differ- ence （P〈0.05） ,the P-L value was （70.72±7.4）HU and （74.15±6.5）HU respectively,with no statistic difference （P〉 0.05）. In the ascites group and with no ascites group,the peak time of MPV was （42.4±3.1）s and （41.3±2.0）s respec- tively,with no statistic difference （P〉0.05）;the P L value was （73.01±10.0）HU and 74. 15HU respectively, with no statistic difference （P〉0.05）. In the varicosis group and with no varicosis group,the peak time of MPV was （61.2±5.6） s and （40.1±2. 1）s respectively,with significant statistic difference （P〈0. 05） ;the P-L value was （41.92±6.8）HU and （ 71.58 ± 4.90） HU respectively, with significant statistic difference （ P 〈 0.05 ）. Conclusion： The MPV delay time of hepa- tochirrosis accompanied with different pathological changes varied. Understanding of the different pathological situation cau sing various delay time of MPV is useful in displaying the portal vein imaging.
