Use of long-term catheters in Japan: implant procedures, maintenance methods, and future aspects

Area of Science:

• Nephrology
• Vascular Surgery
• Medical Device Engineering

Background:

• The Japanese Society for Dialysis Therapy (JSDT) issued guidelines in 2011 for vascular access in chronic hemodialysis.
• These guidelines restrict the use of long-term catheters due to significant risks of infection (sepsis) and catheter obstruction by thrombus.

Purpose of the Study:

• To address the anticipated increased need for long-term catheters in Japan.
• To highlight the necessity for enhanced catheter materials and structures resistant to complications.

Main Methods:

• Analysis of current JSDT guidelines regarding vascular access for chronic hemodialysis.
• Consideration of demographic trends in Japan and their impact on dialysis patient population.
• Evaluation of the limitations and risks associated with existing long-term catheter technology.

Main Results:

• Current guidelines strictly limit the use of long-term catheters.
• High risks of sepsis and thrombotic obstruction are primary concerns.
• Japan's demographic changes predict a greater demand for long-term catheter use within the next decade.

Conclusions:

• Despite current restrictions, long-term catheters will likely be required more frequently in Japan.
• Development of advanced catheter materials and designs is crucial.
• Future innovations must focus on improving resistance to infection and thrombosis for chronic hemodialysis patients.
