摘要
目的:探讨64层螺旋CT双通路注射法行门腔静脉同步成像技术在布-加综合征(BCS)诊断中的应用价值。方法:选择行64层螺旋CT双通路注射法造影并经数字减影血管造影(DSA)证实的20例BCS患者,对其影像资料进行回顾性分析。结果:①血管重建显示:单纯下腔静脉受累7例;单纯肝静脉受累5例;下腔静脉伴肝静脉受累4例;下腔静脉血栓、外压性狭窄病变4例。与DSA进行比较,符合率达95%,二者具有较好的相关性,r值=0.966。②肝实质动态增强扫描显示:典型斑片样强化12例;3例不典型强化;5例肝实质未见明显异常强化。结论:64层螺旋CT双通路注射法行门腔静脉同步成像技术在诊断BCS中有较高的临床应用价值,同时能更好地显示门静脉与下腔静脉,准确、完整地显示BCS的梗阻部位和性质。
Objective： To explore the application value of 64-slice spiral CT with dual-path injection angiography in diagnosis of the Budd-Chiari syndrome. Methods： Retrospectively analysis of the general information of 20 patients with Budd-Chiari syn drome were performed, who Were scanned by 64-slice spiral CT with dual-path injection angiography. Results： 7 cases simply involved inferior vena cava,5 cases involved hepatic vein,and 4 cases showed inferior vena cava with hepatic vein involvement,4 cases were with inferior vena cava thrombosis and stenosis of external pressure. Compared with DSA, the CTA results were positively correlated with the DSA results （r value=0. 966）. 12 cases had typical spot-like enhancement,3 cases had no significant spot-like enhancement, 5 cases had no enhancement. Conclusion：64-slice spiral CT with dual-path injection angiography has clinical application value,and can show inferior vena cava and portal vein clearly in the same time.
