Monitoring of hepatic vein
oxygen saturation is invasive and involves the insertion of a hepatic catheter.
A: Coronal computed tomography image of thorax/abdomen/pelvis with intravenous contrast demonstrating a large tumour thrombus extending into the right hepatic vein
(double arrows) and just below the right atrium (single arrow).
These complications can occur either during access to the hepatic vein
or during the creation of an intrahepatic tract or during manipulation of the portal vein and stent placement.
In another case where two Wallstents were deployed with partial overlap, it was not technically possible to remove the Wallstent from the hepatic vein
and IVC; only the more cephalad Wallstent could be snared from the heart and repositioned into the femoral vein, where it was left (5).
A 32-mm compliant CODA balloon catheter (Cook Medical, Bloomington, IN) was advanced to the tip of the guidewire and an inflated, occluding the IVC and hepatic veins
Instead of IVC, hepatic veins
emptied into right atrium individually at the substernal echocardiographic view (Fig.
Central vein: Blood exits each liver lobule by way of the central vein, which feeds into the hepatic vein
Jenkins described hepatic veins
that were "not supposed to be there" in normal livers, patients with three portal veins where surgeons expected to find two, and the unexpected effects of collateral blood vessels that drain the middle hepatic vein
This technique is combined with hepatic venous outflow control of the respective hepatic vein
at its confluence with the IVC, to control back-bleeding.
Reassessing the role of medical therapy in the management of hepatic vein
TIPS involves creation of a low resistance channel between hepatic vein
and the intra-hepatic portion of portal vein using angiography.
Other therapies are being used, including the transjugular intrahepatic portal systemic shunt (TIPS), in which a long catheter is inserted via the jugular vein in the neck, advanced into a hepatic vein
and then into a large branch of the portal vein in the liver.
