A Central Venous Catheter (CVC) is a thin, flexible tube inserted into a large vein, typically in the neck, chest, or groin. It allows for the administration of medications, fluids, and nutrients directly into the bloodstream. CVCs are often used for patients requiring long-term treatment, such as those undergoing chemotherapy or needing frequent blood draws. The procedure to place a CVC is usually performed by a healthcare professional under sterile conditions. Once in place, the catheter can remain for days to weeks, depending on the patient's needs. Proper care and monitoring are essential to prevent complications like infections or blood clots.
