MSCT angiography in diagnosis of portal vein anomalies in children

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.
