Abstract:
Objective To evaluate the application value of MSCT in preoperative diagnosis and postoperative evaluation in children with cavernous transformation of the portal vein (CTPV).Methods 11 children diagnosed with CTPV by surgery were included in this study in our hospital.All patients underwent both plain and enhanced MSCT scans before surgery,and ultrasound or MSCT scan after surgery.Results In all 11 cases,preoperative CT showed different degrees of splenomegaly and the plain CT showed abnormal soft tissue mass in the hepatic hilar area.Enhanced CT showed stenosis or occlusion of portal vein trunk,earthworm-like blood vessels in the hilar region,and that the left and/or right branch of intrahepatic portal vein were replaced by multiple densely-distributed blood vessels (typeⅡ). Superior mesenteric-intrahepatic left portal shunt (Rex surgery)was performed in all 11 cases with successful results.All patients were followed up for 2-20 months after surgery.Imaging examinations showed anastomotic patency in 9 cases and stenosis in 2 cases.Conclusion MSCT findings of CTPV in children have certain characteristics.MSCT plays an important role in preoperative diagnosis and postoperative evaluation of CTPV in children.
