The Critical Role of Chemotherapy Ports in Long-Term Treatment
Chemotherapy Implanted ports, also known as implantable ports or port-a-caths, are semi-implantable vascular access devices designed for patients requiring long-term intravenous therapy. Used primarily in chemotherapy, prolonged antibiotic treatment, and total parenteral nutrition (TPN), these devices provide a stable, repeatable access point for drug delivery while reducing the discomfort and complications associated with peripheral IVs.
Each port consists of a small reservoir (port chamber) implanted under the skin, usually in the chest or upper arm, connected to a catheter that leads into a major vein. The device is accessed by inserting a Huber needle through the skin into a self-sealing silicone septum, allowing for multiple drug infusions, blood draws, and fluid administration over months or even years. Once treatment is complete, the port can be surgically removed.
While these devices improve patient comfort and treatment efficiency, their long-term performance depends on their ability to resist thrombosis, infection, and mechanical degradation. Addressing these challenges through advanced surface engineering is essential for improving patient outcomes.
Challenges in Chemotherapy Port Performance
One of the primary complications associated with chemotherapy ports is thrombosis. Over time, blood components can adhere to the catheter’s surface, leading to clot formation that obstructs the device. If thrombosis occurs at the catheter tip, it can block medication delivery and increase the risk of deep vein thrombosis (DVT). Maintaining a hemocompatible surface that prevents platelet adhesion is critical to ensuring the port remains functional for the duration of the treatment. Coatings that provide low-thrombogenic surfaces or controlled-release anticoagulant properties can help mitigate this risk.
Infection is another significant concern. Even though the port is implanted beneath the skin, bacteria can still enter through repeated needle punctures or travel along the catheter lumen. Catheter-related bloodstream infections (CRBSIs) are a leading cause of complications in vascular access devices, often due to biofilm formation on the internal surfaces. Once a biofilm develops, it becomes highly resistant to antibiotics, increasing the likelihood of sepsis or requiring port removal. Antimicrobial coatings that inhibit bacterial adhesion formation can help prevent these complications, reducing infection rates and improving device longevity.
Beyond clotting and infection risks, chemotherapy ports must also remain mechanically durable over time. Repeated needle punctures can weaken the silicone septum, causing leaks or compromising access. Additionally, prolonged implantation can lead to tissue irritation, fibrosis, or discomfort, affecting patient tolerance. Biocompatible surface modifications can minimize inflammatory responses and improve patient comfort, while reinforced polymer coatings can enhance septum durability, ensuring the device withstands thousands of punctures without degradation.
