Portal vein embolization (PVE) is a preoperative procedure performed in interventional radiology to initiate hypertrophy of the anticipated future liver remnant a couple weeks prior to a major liver resection procedure. The procedure involves injecting the right or left portal vein with embolic material to occlude portal blood flow.
The portal vein is not a true vein, because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system , one of three portal venous systems in the human body; the others being the hypophyseal and renal portal systems.
An interventional radiologist can offer a minimally invasive treatment option for pelvic congestion syndrome: ovarian vein embolization; Ovarian vein embolization is a same-day treatment which takes place in an interventional radiology suite. The interventional radiologist gains access through a large vein in the groin, called the femoral vein ...
The rationale for the use of bland embolization for hepatocellular carcinoma (HCC) and/or other hyper-vascular tumors is based on the fact that a normal liver receives a dual blood supply from the hepatic artery (25%) and the portal vein (75%). As the tumor grows, it becomes increasingly dependent on the hepatic artery for blood supply.
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
The "Alternatives to Detention" program is tracking more than 25,000 migrants using ankle and wrist-worn monitors, which costs taxpayers an average of nearly $80,000 each day, according to ICE data.
Tesla CEO Elon Musk has become the first person to top a net worth of $400 billion, according to Bloomberg News. Musk's wealth, which was last counted at $384 billion by the Bloomberg Billionaires ...
Due to the liver's dual blood supply from the hepatic artery and portal vein, interruption of the flow through the hepatic artery was demonstrated to be safe in patients. Tumor embolization eventually developed, blocking the vascular supply to a tumor by primarily endovascular approaches.
