A central venous catheter placed in a vessel through the arm is known as?

The term for a central venous catheter that is placed in a vessel through the arm is a Peripherally Inserted Central Catheter, often abbreviated as PICC. This type of catheter is specifically designed to be inserted into a peripheral vein—typically in the arm—and then advanced until the tip of the catheter is located in the central venous system, usually at the level of the superior vena cava near the right atrium.

The reason this option is correct lies in the definition and application of a PICC line. It is advantageous for long-term intravenous access because it can remain in place for weeks to months, allowing for the administration of medications, fluids, nutrients, or blood products without the need for repeated needle sticks. Its placement is generally performed with the assistance of ultrasound for anatomical guidance, enhancing the safety and efficacy of the procedure.

In contrast, a Port-a-cath refers to a different type of central venous access device that is implanted subcutaneously and allows for repeated access through a portal. A central line can refer to any line that is inserted into the central venous system, which encompasses a variety of access devices; however, it does not specifically denote that the entry was made through a peripheral site such as the arm.
