Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
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.
Hemorrhoidal artery embolization (HAE, or hemorrhoid artery embolization) is a non-surgical treatment of internal hemorrhoids. [ 1 ] The procedure involves blocking the abnormal blood flow to the rectal (hemorrhoidal) arteries using microcoils and/or microparticles to decrease the size of the hemorrhoids and improve hemorrhoid related symptoms ...
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.
Bronchial artery embolization to control hemoptysis: comparison of N-butyl-2-cyanoacrylate and polyvinyl alcohol particles An important paper with long-term results from Seoul National University encompassing 406 cases (293 PVA cases, 113 NBCA cases). The non-hemoptysis survival rates at 1, 3, and 5 years for PVA were 77%, 68%, and 66% ...
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 ...
Uterine artery embolization (UAE, uterine fibroid embolization, or UFE) is a procedure in which an interventional radiologist uses a catheter to deliver small particles that block the blood supply to the uterine body. The procedure is primarily done for the treatment of uterine fibroids and adenomyosis.
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
