| Popis: | Objectives: To determine the accuracy of Duplex ultrasound in the assessment of pathology or an anomaly of the inferior vena cava (IVC). Methods: Duplex ultrasound was performed in 60 pediatric liver transplant candidates. The findings were retrospectively correlated with the results of cavography (n = 9) or peroperative findings during orthotopic liver transplantation (OLT, n = 51). Results: In 56 out of the 60 children (93%), Duplex ultrasound correlated well with cavography or peroperative findings, but there were three false-positive and one false-negative (sensitivity 80%, specificity 95%, positive predictive value 57%, negative predictive value 98%). Accuracy is significantly improved, if both the retrohepatic segment and the suprahepatic segment of the IVC, including its junction with the right atrium, can be visualized. Conclusions: Duplex ultrasound is the method of choice, but cavography is necessary if the upper part of the IVC is not well demonstrated. |
