Vascular Access Techniques

1. Introduction & Overview

Vascular access techniques are essential in oncology care to allow safe, pain-free administration of chemotherapy drugs, blood transfusions, and intravenous fluids, avoiding repeated needle pricks and venous scarring.

2. Key Indications for Vascular Access

Common scenarios where a dedicated vascular access device is recommended:

• Patients scheduled to undergo multiple cycles of chemotherapy treatment.
• Administration of irritant or vesicant chemotherapy drugs (such as anthracyclines).
• Long-term intravenous antibiotics, fluids, or total parenteral nutrition (TPN).
• Frequent blood sampling and monitoring to minimize patient discomfort.

3. Diagnostic & Pre-operative Pathway

Meticulous evaluations are performed prior to device insertion to ensure patient safety:

• Venous Doppler Ultrasound: Assessing target veins (internal jugular, subclavian, or cephalic) to ensure patency.
• Coagulation Profiling: Evaluating platelet count and INR to minimize bleeding risks during insertion.
• Regimen Mapping: Determining the optimal device based on the specific chemotherapy duration and frequency.

4. Specialized Vascular Access Options

Dr. Parveen Mendiratta provides comprehensive vascular access procedures:

• Chemotherapy Ports (Chemo Port): A subcutaneous port chamber connected to a central catheter, inserted under local anesthesia, completely hidden under the skin for long-term treatment.
• PICC Lines (Peripherally Inserted Central Catheter): A catheter inserted through a peripheral arm vein and advanced to the large veins near the heart, ideal for intermediate-term therapy.
• Hickman / Central Lines: Tunneled central venous catheters exiting the chest wall, used for frequent chemotherapy or bone marrow transplant regimens.

5. Care & Recovery Guidance

Port insertions are quick outpatient day-care procedures performed under local anesthesia. An immediate post-operative chest X-ray confirms optimal catheter tip placement. Simple port flushing protocols (with heparinized saline) are implemented to prevent clotting and ensure long-term device patency.
