What Is It?
Interventional radiology (IR) plays a significant role in the insertion of peripherally inserted central catheters (PICC lines). A PICC line is a long, thin catheter that is inserted into a vein in the arm and advanced until the tip reaches a large vein near the heart. This allows for the administration of medications, fluids, and other treatments over an extended period.
Interventional radiology offers several advantages for PICC insertion, including improved accuracy, reduced risk of complications, and the ability to access difficult-to-reach veins under imaging guidance. Additionally, the procedure can often be performed on an outpatient basis, minimizing hospital stays and patient discomfort.
How Is It Treated?
Here’s a general overview of the process:
- Preparation – The patient is positioned comfortably on the procedure table. The arm chosen for insertion is typically cleaned and draped in a sterile fashion.
- Local Anesthesia – A local anesthetic is administered to numb the area where the catheter will be inserted. This helps minimize discomfort during the procedure.
- Vein Access – Using ultrasound guidance, the interventional radiologist locates a suitable vein for PICC insertion. Ultrasound helps visualize the veins in real-time, increasing the accuracy of catheter placement.
- Insertion – Once the vein is identified, a needle is inserted into the vein under ultrasound guidance. A guidewire is then threaded through the needle into the vein.
- Catheter Advancement – The catheter, which is measured based on the patient’s anatomy, is advanced over the guidewire until the tip is positioned in a large central vein near the heart. Confirmation of correct placement may be done through imaging techniques such as fluoroscopy.
- Securing the Catheter – Once the catheter is in place, it is secured to the patient’s skin using sutures, adhesive dressings, or other securement devices to prevent accidental displacement.
How Do I Prep For The Procedure?
Before the procedure, the patient’s medical history, current medications, and any allergies are reviewed. Additionally, the patient’s veins are assessed to determine the most appropriate site for PICC insertion.
The procedure is explained to the patient, including its purpose, risks, and benefits. Informed consent is obtained.
What Happens After The Procedure?
After the procedure, the insertion site is monitored for any signs of complications such as bleeding or infection. The patient is usually instructed on how to care for the PICC line and when to follow up with healthcare providers.
