Insights
The Dialock access device for haemodialysis showed acceptable patency, comparable to arteriovenous fistulas, despite complications like bleeding and infection in some patients.
Area of Science:
- Nephrology
- Vascular Surgery
Background:
- Vascular access is crucial for haemodialysis.
- The Dialock device was evaluated for its efficacy and safety.
Observation:
- A retrospective study of 7 patients using 10 Dialock devices (2000-2004).
- Mean patency was 16.3 months.
- Complications included bleeding (3 patients) and infection (4 patients).
Findings:
- Dialock demonstrated 1-year patency rates similar to arteriovenous fistulas.
- 3 out of 7 patients experienced no complications.
Implications:
- Dialock is a viable option for haemodialysis patients with vascular access challenges.
- Future similar devices may address needs for patients with difficult vascular access.
Objective:
To study the patency and complications associated with the Dialock, an access device for haemodialysis.
Material And Methods:
The records of seven Swedish patients who were treated with the Dialock access device between 2000 and 2004 were studied retrospectively.
Results:
A total of 10 Dialock devices were used in seven patients. The mean period of patency was 16.3+/-13.8 months. Major complications observed were bleeding in the dose pocket in three patients and infection in four. Three patients experienced no complications. The 1-year patency was similar to that of a newly created arteriovenous fistula used in our unit.
Conclusions:
In spite of the associated complications, the Dialock is an acceptable access device for haemodialysis patients with vascular access problems. Although the Dialock is no longer available on the market, similar access devices may be of importance in the future.
