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 ...
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.
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 ...
1930 – First therapeutic embolization procedure (of a carotid-cavernous fistula); described by Brooks. [30] 1960s – Radioisotopes such as Yttrium-90 (Y90) started to be investigated for the use in cancer treatments. 1966 – Embolization therapy to treat tumors and spinal cord vascular malformations by blocking the blood flow.
It was pioneered in 1927 by the Portuguese neurologist Egas Moniz at the University of Lisbon, who also helped develop thorotrast for use in the procedure. [ 2 ] Typically a catheter is inserted into a large artery (such as the femoral artery ) and threaded through the circulatory system to the carotid artery , where a contrast agent is injected.
Surgical embolectomy for massive pulmonary embolism (PE) has become a rare procedure and is often viewed as a last resort. Thrombolytic therapy has become the treatment of choice. [1] Surgical or catheter embolectomy is a procedure performed in patients with pulmonary embolism, which is a blockage of an artery in the lung caused by a blood clot.
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.
An embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. [5] An arterial embolus might originate in the heart (from a thrombus in the left atrium, following atrial fibrillation or be a septic embolus resulting from endocarditis).
