Late vascular complications of the subclavian dialysis catheter
Insights
Subclavian dialysis catheters may cause central vein stenosis, a long-term complication affecting hemodialysis access. This stenosis can compromise ipsilateral arteriovenous fistulas, requiring awareness among clinicians.
Area of Science:
- Nephrology
- Vascular Surgery
- Interventional Radiology
Background:
- Subclavian dialysis catheters are commonly used for temporary vascular access in hemodialysis patients.
- Long-term sequelae associated with subclavian catheter use are generally considered minimal.
Observation:
- Three hemodialysis patients developed central vein stenosis after subclavian catheter placement.
- Stenosis manifested months after the creation of an ipsilateral arteriovenous fistula.
- The compromised fistula indicated the clinical significance of the central vein stenosis.
Findings:
- Central vein stenosis is a potential long-term complication of subclavian dialysis catheters.
- This stenosis can negatively impact the function of ipsilateral arteriovenous fistulas.
- Balloon angioplasty may be an effective treatment for these stenotic lesions.
Implications:
- The use of subclavian dialysis catheters may be associated with significant long-term sequelae.
- Clinicians should be aware of the risk of central vein stenosis and its effect on future vascular access.
- Further research is needed to determine predisposing factors and the incidence of this complication.
Abstract:
The use of the subclavian dialysis catheter is generally regarded as free of long-term sequelae. However, we observed the occurrence of central vein stenosis in three hemodialysis patients following the use of the subclavian dialysis catheter to provide temporary access. In each case, the stenosis became clinically apparent months after the establishment of an ipsilateral arteriovenous fistula that became compromised by the stenosis. The stenoses may be amenable to dilatation by balloon angioplasty. Although the factors predisposing to this complication and its incidence are unknown, the potential for compromising access sites in the ipsilateral arm warrants awareness that use of subclavian dialysis catheters may be associated with significant long-term sequelae.
