Pathology of catheter-related complications: what we need to know and what should be discovered

Area of Science:

• Nephrology
• Vascular Access
• Pathology

Background:

• Tunneled cuffed catheters remain a critical vascular access method for hemodialysis patients.
• Despite efforts to promote autogenous fistulas, a significant portion of the hemodialysis population relies on these catheters.
• Catheter-related complications significantly increase patient morbidity and mortality and strain healthcare resources.

Purpose of the Study:

• To review the pathological aspects of complications associated with tunneled cuffed catheters in hemodialysis.
• To identify knowledge gaps and areas requiring further translational research.
• To propose future research strategies and innovations for complication prevention.

Main Methods:

• Comprehensive review of recent literature on catheter-related complications.
• Focus on the pathological mechanisms underlying these complications.
• Analysis of current research trends and future directions.

Main Results:

• Tunneled cuffed catheters are associated with diverse complications including thrombosis, infection, fibrin sheath formation, and central vein stenosis.
• While management strategies are increasingly studied, the underlying pathology of these complications requires deeper investigation.
• Significant knowledge gaps exist regarding the precise pathological pathways leading to catheter dysfunction.

Conclusions:

• Understanding the pathology of catheter-related complications is crucial for developing effective prevention and management strategies.
• Further translational research is needed to elucidate the mechanisms of thrombosis, infection, and stenosis.
• Future innovations should focus on addressing the root pathological causes to improve patient outcomes and reduce healthcare burden.
