| 目的 探讨螺旋CT血管造影(MSCTA)在儿童先天性门静脉畸形诊断中的价值。方法 对超声诊断或疑诊的7例儿童门静脉畸形患儿行MSCTA检查。对所有图像进行VR、MIP和(或)曲面重建(CPR)重建门静脉,分析门静脉畸形的影像学特征。结果 7例患儿中, 4例诊断为门静脉海绵样改变,典型表现为第一肝门区见肝内门静脉周围纡曲、扩张、窦隙样网状血管结构;Abernethy畸形2例,其中1例门静脉缺如,门静脉走行区未见正常门静脉影像,下腔静脉绕行腹主动脉异常走行,1例门静脉与下腔静脉伴行直接汇入右心房,未见相互交通;1例门静脉瘤样扩张,门静脉主干明显增宽,肝内门静脉正常。结论 MSCTA对诊断儿童先天性门静脉畸形、判断其分型具有较高的应用价值。 |

| Objective To observe the value of MSCTA in diagnosis of portal vein anomalies (PVA) in children. Methods Seven patients with ultrasound diagnosed or suspected PVA underwent MSCTA. VR, MIP, and (or) curved multiplanar reformations (CPR) were performed, and the characteristics of the images were analyzed. Results Cavernous transformation of portal vein was detected in 4 children, MSCTA displayed the tortuositas, dilated cancellous vessel structure in the area of the first hepatic hilar region surrounding the portal vein. Abernethy malformation was found in 2 patients, 1 with absent portal vein and the inferior vena cava surrounding the abdominal aorta, the other one with portal vein accompanied with inferior vena cava directly draining into right atrium, but the two vessels being not communicated. Portal vein aneurysm dilatation was defined in 1 patient, MSCTA found the main portal vein widen, but introhepatic portal vein branches were normal. Conclusion MSCTA has high application value in diagnosing and classifying of PVA in children. |
