2022年7月31日 · Congenital portosystemic shunts are rare, extrahepatic or intrahepatic, anatomical abnormalities shunting blood from the portal venous system to the systemic venous system and, thus, avoiding passage through the hepatic acinus.

Intrahepatic portosystemic venous shunts (IPSVSs) are rare vascular malformations. They can be asymptomatic or present with various symptoms including encephalopathy. We present two cases of IPSVS, one involving a patient presenting with altered mental status and the …

We present two cases of congenital intrahepatic portosystemic shunts in which the right portal vein directly communicated with the inferior venacava (IVC) in one patient and with the hepatic vein in the other.

2023年7月24日 · Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established percutaneous modality for decreasing portal hypertension. The major clinical indications for transjugular intrahepatic portosystemic shunts include refractory variceal hemorrhage and refractory ascites.

CT study shows a small stellar dilated vascular lesion at the superior aspect of the right hepatic lobe measures 1.5 cm, appearing to communicate with both peripheral right portal and hepatic veins branches. It elicits low density in the non-enhanced CT study and homogenously enhanced in the Porto-venous phase.

2024年11月2日 · Transjugular intrahepatic portosystemic shunt (TIPS or TIPSS) is a treatment for portal hypertension in which direct communication is formed between a hepatic vein and a branch of the portal vein, thus allowing some proportion of portal flow to bypass the liver. The target portosystemic gradient after TIPS formation is <12 mmHg.

2024年5月28日 · Congenital portosystemic shunts (CPSS) are a rare developmental anomaly diverting blood flow from the portal venous system and the liver to the systemic venous system.

Transjugular intrahepatic portosystemic shunt was generally considered as a first-line therapy in the definitive treatment of portal hypertension concomitant with variceal bleeding; however, trials comparing TIPS with surgical shunts were few and drew little attention, so some disadvantages of TIPS were ignored. In this meta-analysis, we ...

2025年1月21日 · Portosystemic shunts in growth-restricted fetuses are more common than previously thought. We aimed to describe fetuses with growth restriction and transient oligohydramnios in which a congenital intrahepatic portosystemic shunt …

2018年6月7日 · Intrahepatic portosystemic venous shunt is a rare condition defined as communication between the intrahepatic portal vein and systemic veins, including the hepatic vein and perihepatic vein, via an anomalous intrahepatic venous channel.
