The hemodialysis catheter conundrum: hate living with them, but can't live without them
1Duke University Medical Center, Durham, North Carolina, USA.
Insights
Hemodialysis catheters are vital for vascular access but present significant infectious and thrombotic complications. This review details these issues and proposes solutions for managing hemodialysis catheter dilemmas.
Area of Science:
- Nephrology
- Vascular Access
Background:
- Hemodialysis necessitates reliable circulation access, traditionally via arteriovenous fistulae or grafts.
- Hemodialysis catheters, both temporary and cuffed, have become crucial for dialysis delivery.
- Catheter use introduces significant anatomic, thrombotic, and infectious complications, posing challenges for nephrologists.
Purpose of the Study:
- To review the benefits, complications, and dilemmas associated with hemodialysis catheters.
- To provide a comprehensive overview of current hemodialysis vascular access options.
Main Methods:
- A comprehensive literature review was conducted.
- The review focused on the types, usage, and challenges of hemodialysis catheters.
Main Results:
- Hemodialysis catheters offer significant utility but are associated with considerable morbidity.
- Complications include infection, thrombosis, and anatomical issues.
- The review details these benefits and complications.
Conclusions:
- Hemodialysis vascular access catheters are indispensable for patient care.
- Managing the high rates of infectious, thrombotic, and anatomical complications is critical.
- Proposed guidelines aim to address these challenges and improve patient outcomes.
Background:
Hemodialysis requires reliable recurrent access to the circulation. On a chronic basis, this has been best provided by the use of arteriovenous fistulae and arteriovenous grafts. In recent years, hemodialysis catheters have come to play an increasingly important role in the delivery of hemodialysis. The use of both temporary as well as cuffed hemodialysis catheters has emerged as a significant boon for both patients and practicing nephrologists. The complications, however, associated with each of these hemodialysis catheters, both in terms of anatomic, thrombotic, and infectious issues, have emerged as a major problem with their continued use. This significant morbidity and complication rate has forced many nephrologists to face a basic conundrum: they have come to hate having to deal with the problems inherent in catheter usage, but the enormous utility of these devices have forced physicians to accept the fact they cannot live without them in their current practice.
Methods:
We used a comprehensive literature review to describe the types, use and dilemmas of hemodialysis catheters.
Results:
This article provides a comprehensive review of both the benefits inherent with the use of these hemodialysis catheters while cataloging their complications and offering some possible solutions.
Conclusion:
Hemodialysis vascular access catheters are essential in the maintenance of hemodialysis vascular access. However, they have a significant infectious, thrombotic, anatomic complication rate that are detailed with proposed problem-solving guidelines.
