Abstract

We present a new case of congenital absence of the portal vein and focal nodular hyperplasia in the liver without additional congenital anomalies. Ultrasound, computed tomography, magnetic resonance imaging, and angiography depicted the splenic vein and the superior mesenteric vein joining and entering into the inferior vena cava without passing through the liver. The features of this patient and the 30 previously reported cases are reviewed.

Abstract

Background: The aim of the study was to evaluate intrahepatic portosystemic venous shunts (IPSVS) patterns and to determine the role of Color Doppler sonography in the diagnosis and evaluation of related hemodynamic changes in portal perfusion., Methods: Sonography and Color Doppler imaging were performed in nine patients with IPSVS. Type and Doppler waveform of the shunt were determined; velocity measurements in the portal trunk and portal branches were studied to evaluate the effects of the shunt on intrahepatic circulation. Computed tomography was performed in six patients, magnetic resonance imaging in three patients, and angiography in two patients., Results: The shunt between the portal and hepatic veins was aneurismal in six patients, while localized peripheral shunt with multiple tortuous vessels in one hepatic segment was observed in three patients. The shunts showed continuous low velocity spectral tracings and in the aneurismal shunts a low velocity bi-directional or helicoidal flow was detected. The feeding portal branches and the draining hepatic veins showed anomalous Doppler tracings and alterations of intrahepatic portal perfusion were observed in three cases., Conclusion: Color Doppler is essential for proper diagnosis of IPSVS and for evaluation of related hemodynamic changes in portal perfusion.
