Which CVAD is commonly used for vascular access lasting about 1 week to 6 months and is inserted in the arm?

• A. PICC
• B. Short peripheral IV
• C. Implanted port
• D. Arteriovenous graft

Answer: (A)

The main idea is matching how long you need IV access with the type of device and where it’s placed. A PICC fits when you want reliable central venous access for a middle-term period, roughly from about one week up to several months, and you insert it in a vein in the arm that is then threaded to the central veins with the tip in the lower part of the superior vena cava. This arm-based approach avoids a surgical chest implant and is practical for outpatient care.

Short peripheral IVs are intended for short-term use (hours to a few days) and stay in the peripheral veins, not central, so they aren’t suitable for weeks to months of therapy. An implanted port is a long-term central access option that requires surgical placement and is usually implanted in the chest (though arm ports exist) and is more invasive, making it less ideal for a 1-week-to-6-month course when an arm PICC can suffice. An arteriovenous graft is used for hemodialysis, involving an artery-to-vein connection in the arm, and isn’t used for daily IV therapy.
