TACE of liver tumors derives its beneficial effect by two primary mechanisms. [3] Most tumors within the liver are supplied by the proper hepatic artery, so arterial embolization preferentially interrupts the tumor's blood supply and stalls growth until neovascularization. Secondly, focused administration of chemotherapy allows for delivery of ...
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 ...
Debulking is the reduction of as much of the bulk of a tumour without the intention of a complete eradication. It is usually achieved by surgical removal. [1] [2] When performed for curative intent, it is a different procedure, which is called surgical debulking of tumors is known as cytoreduction or cytoreductive surgery [3] (CRS); "cytoreduction" refers to reducing the number of tumor cells.
Seki et al. reported the usefulness of endovascular treatment for lung cancer hemoptysis. [7] Kichang et al. reported BAE for hemoptysis in 84 lung cancer patients, and demonstrated that massive hemoptysis and cavity formation were significantly poor prognosis factors; re-hemoptysis rate was 23.8% in their follow-up period.

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 ...
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.
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).
Awake craniotomy is a neurosurgical technique and type of craniotomy that allows a surgeon to remove a brain tumor while the patient is awake to avoid brain damage.During the surgery, the neurosurgeon performs cortical mapping to identify vital areas, called the "eloquent brain", that should not be disturbed while removing the tumor.
