About Potential Complications Associated With Haemodialysis Catheters

 

Haemodialysis is a treatment used when kidneys fail (Stage 5 Kidney Disease) and can no longer clean blood and remove extra fluid from your body. A haemodialysis access or vascular access is a way to reach your blood for haemodialysis.

 

Haemodialysis Catheters are implanted and used in haemodialysis (treatment to filter waste and water from the blood), apheresis (a technology that separates donated blood components to treat certain illnesses), and infusion (a method of putting fluids into the bloodstream) for up to 21 days.

 

A 2018 estimate put the number of patients on chronic dialysis in India at about 175,000, giving a prevalence of 129 per million population.

 

Dialysis catheters are used either as temporary solutions or as a bridging device while patients wait for fistula or graft maturation or kidney transplantation, or as the sole chronic access method. Complications associated with dialysis access, and especially with dialysis catheters, are on the rise as patients diagnosed with end stage renal disease (ESRD) are increasing both in age and in co-morbidities.

 

Complications of Haemodialysis Catheters include infection, thrombosis, cardiac arrthymia, entrapped guide wire and malposition.

 

Recently, based on complaints of injuries, US FDA ordered recall for a Dual Lumen High Flow Catheters manufactured by a leading medical device company due to a potential catheter hub defect that may cause leaks across the catheterís tubes. During treatment, this leak could result in mixing of the arterial and venous blood, lead to increased recirculation and poor dialysis, or cause the development of blood clots in the blood vessels.

 

The use of the defective catheter may cause serious adverse health outcomes, including bleeding or the need for surgical removal and replacement of the affected catheter.
