Sonographic Diagnosis of Preduodenal Portal Vein in Children

Purpose: To clarify the role of sonography in diagnosis of Preduodenal Portal Vein (PDPV) in children. Material and methods: We present two cases with PDPV in children proved with surgery. The first case was diagnosed retrospectively, the second one prospectively. Results: In both cases the PDPV appears above the duodenum with convexity which is opposite of normal concave configuration of PV. Both cases appear with multiple congenital association anomalies. Conclusions: The sonography is safe, convenient, fast, time- effective and cost- effective method for precise diagnosis of PDPV in children.
