The most common type of intrahepatic portal venous shunt is a portal venous communication to an extrahepatic systemic vein (perihepatic veins or the inferior vena cava) in a patient with portal venous hypertension caused by cirrhosis.

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 …

2000年1月1日 · Three types of intrahepatic shunts between the major vessels of the liver are possible: portosystemic venous (portal vein to hepatic vein or vena cava), arterioportal (hepatic artery to portal vein), and arteriosystemic (hepatic artery to hepatic vein). Visualization of these shunts on cross-sectional imaging is unusual.

On angiography, two types of intrahepatic portosystemic venous shunt were seen: intrahepatic portal venous–hepatic venous communication and intrahepatic portal venous–perihepatic venous communication. Transcatheter embolization is effective for …

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. Multiple hepatic nodules consistent with focal nodular hyperplasia (FNH) were seen in the first patient.

Intrahepatic portal-systemic venous shunt is defined as a communication between the portal and the systemic-venous circulation, measuring more than 1 mm in diameter and at least partially located inside the liver. This is a rare condition, and the etiopathogenesis is unclear.

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.

2024年1月8日 · • Multiple techniques exist to assist in portal venous puncture during a transjugular in­trahepatic portosystemic shunt. • Each portal vein access technique carries a unique set of risks, benefits, advantages, and disadvantages. • Knowledge of these techniques increases the likelihood of a safe and successful pro­cedure.

2023年6月8日 · DSA and fluoroscopic images of the Portal Vein Recanalization–Transjugular Intrahepatic Portosystemic Shunt (PVR-TIPS) with percutaneous ultrasound-guided superior mesenteric vein (SMV) access and balloon-assisted shunt placement.

2011年3月1日 · To propose a strategy for early diagnosis and management of intrahepatic vascular shunts (IHVSs). We systematically screened 3143 patients liable to develop IHVSs. Diagnosed patients were comprehensively evaluated using color Doppler and multiphasic CT.
