Insights
Subclavian vein thrombosis occurred in six patients undergoing hemodialysis via catheterization. Prolonged catheter use and repeated procedures increase the risk of this serious complication.
Area of Science:
- Nephrology
- Vascular Surgery
- Internal Medicine
Background:
- Subclavian vein catheterization is a preferred vascular access for hemodialysis due to its longevity, lower infection risk, and patient comfort.
- Despite advantages, catheter-related complications, including thrombosis, remain a concern in hemodialysis access management.
Observation:
- This study observed six cases of subclavian vein thrombosis among 70 patients undergoing periodical hemodialysis over seven years.
- The cases occurred following transcutaneous catheterization, highlighting a potential risk associated with this procedure.
Findings:
- The incidence of subclavian vein thrombosis was noted in a specific cohort of hemodialysis patients.
- Key contributing factors identified were prolonged catheter dwell time and the frequency of catheterizations.
Implications:
- These findings underscore the importance of vigilant monitoring for thrombosis in hemodialysis patients with subclavian catheters.
- Strategies to mitigate thrombosis risk, such as optimizing catheter duration and minimizing repeat procedures, should be considered in clinical practice.
Abstract:
The authors report six cases of subclavian vein thrombosis after transcutaneous catheterization in a group of 70 patients treated by periodical haemodialysis over a 7-year period in a Nephrology department at Casablanca. The subclavian vein has become the favourite access route in most haemodialysis centres because it can be utilized for a longer time, carries a lower risk of infection and is more comfortable for the patient than the other routes. Two main factors facilitate the occurrence of thrombosis: a long duration of catheter insertion and repeated catheterizations.
