Venous access in haemophilic children: choice and management

Area of Science:

• Pediatric Hematology
• Vascular Access Technologies
• Bleeding Disorders

Background:

• Current pediatric haemophilia treatment necessitates regular intravenous infusions, often requiring prolonged venous access.
• Peripheral veins are preferred, but frequent home infusions pose challenges for young children.
• Central venous access devices (CVADs) are utilized to facilitate treatment but are linked to significant complications.

Purpose of the Study:

• To review the challenges and complications associated with venous access methods in pediatric haemophilia treatment.
• To compare the efficacy and safety of different CVADs and explore alternatives like arteriovenous fistulas.

Main Methods:

• Literature review of current haemophilia treatment protocols and venous access device management.
• Analysis of complication rates and treatment outcomes associated with peripheral veins, CVADs (external non-tunnelled, external tunnelled, ports), and arteriovenous fistulas.

Main Results:

• CVADs, while improving treatment feasibility, are associated with high rates of infection and thrombotic occlusion, potentially interrupting therapy.
• Implantable ports have lower infection rates than external devices but require needle access.
• Arteriovenous fistulas are emerging as a viable alternative with easier use and fewer complications.

Conclusions:

• Optimizing venous access is critical for effective haemophilia management in children.
• Arteriovenous fistulas present a promising alternative to CVADs, offering improved safety and usability for long-term infusion therapy.
