  2. Portal vein embolization - Wikipedia

    en.wikipedia.org/wiki/Portal_vein_embolization

    Preoperative PVE is a very well tolerated procedure with extremely low mortality rates (0.1 percent) and technical failure rates (0.4 percent). [3] Complication rates from the procedure are low as well (2–3 percent) and include portal vein thrombosis, liver infarction, necrosis, infection, pneumothorax, and other risks as listed above. [3]

  3. Embolization - Wikipedia

    en.wikipedia.org/wiki/Embolization

    First developed by Sadek Hilal in 1968, embolization is a minimally invasive surgical technique. [8] The purpose is to prevent blood flow to an area of the body, which can effectively shrink a tumor or block an aneurysm. The procedure is carried out as an endovascular procedure by an interventional radiologist in an interventional suite. It is ...

  4. Portal vein thrombosis - Wikipedia

    en.wikipedia.org/wiki/Portal_vein_thrombosis

    Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver. The mortality rate is approximately 1 in 10.

  5. Transcatheter arterial chemoembolization - Wikipedia

    en.wikipedia.org/wiki/Transcatheter_arterial...

    In 1972, surgical ligation of the hepatic artery was first used to treat recurrent hepatic tumors followed by infusion of 5-fluorouracil into the portal vein. 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.

  6. Hepatic artery embolization - Wikipedia

    en.wikipedia.org/wiki/Hepatic_artery_embolization

    The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked. [2]

  7. Bland embolization - Wikipedia

    en.wikipedia.org/wiki/Bland_embolization

    Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.

  8. Interventional radiology - Wikipedia

    en.wikipedia.org/wiki/Interventional_radiology

    Liver cancer: primary liver tumors such as hepatocellular carcinoma or cholangiocarcinoma and liver metastases are often treated by procedures such as transarterial chemoembolization (TACE), Selective internal radiation therapy (SIRT/Y-90 radioembolization), portal vein embolization, transarterial/bland embolization, or image guided ablation ...

  9. Hepatic portal system - Wikipedia

    en.wikipedia.org/wiki/Hepatic_portal_system

    The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery.
