Port-A Catheter Complications: Incidence, Risk Factors, Prevention, and Management

Port-A catheters (totally implantable venous access devices) are essential for long-term central venous access in patients requiring chemotherapy, parenteral nutrition, or prolonged therapy. Although offering improved quality of life compared to external catheters, these devices have complication rates ranging from 1‒20%. This comprehensive review details major Port-A complications, including infectious, thrombotic, mechanical, and malpositioning complications. Infections (2‒20 % incidence) include port-pocket infections and catheter-related bloodstream infections, with risk factors including hematologic malignancies and neutropenia. Thrombotic complications (3‒8 %) can affect device function and patient outcomes, whereas mechanical complications (1‒10 %) include insertion-related trauma, pinch-off syndrome, and catheter fractures. Malpositioning complications occur initially or as a secondary migration, potentially causing extravasation or thrombosis. Management strategies range from conservative approaches to device removal, with most complications showing favorable outcomes when properly addressed. Our findings revealed that early detection, proper insertion techniques, and standardized management protocols significantly can improve outcomes, highlighting the importance of multidisciplinary care in maximizing device benefits while minimizing risks.
