Vascular access for chemotherapy. In medicine, vascular access is a means of accessing the bloodstream through the peripheral or central blood vessels in order to obtain blood or deliver medications including chemotherapy. A vascular access procedure involves insertion of a sterile plastic tube called a catheter into a blood vessel.
Transcatheter arterial chemoembolization. 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.
Other names. chemo, CTX, CTx.

Metastasis is a pathogenic agent's spread from an initial or primary site to a different or secondary site within the host's body; [1] the term is typically used when referring to metastasis by a cancerous tumor. [2] The newly pathological sites, then, are metastases (mets). [3][4] It is generally distinguished from cancer invasion, which is ...
Doping in sport. Blood doping is a form of doping in which the number of red blood cells in the bloodstream is boosted in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity (VO 2 max) and endurance. [1]
Permanent vein collapse occurs as a consequence of: [citation needed] Repeated injections, especially with blunt needles. Poor injection technique. Injection of substances which irritate the veins; in particular, fluids that are hypertonic (high osmolality), vasoactive, irritants, with an extreme pH (very acidic / alkaline), [3] or liquid methadone intended for oral use.
Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
The absence of blood vessels in a repairing or otherwise metabolically active tissue may inhibit repair or other essential functions. Several diseases, such as ischemic chronic wounds , are the result of failure or insufficient blood vessel formation and may be treated by a local expansion of blood vessels, thus bringing new nutrients to the ...
