Insights
Stenting central arm vein obstructions effectively restores hemodialysis access in patients. This intervention resolves venous hypertension and maintains vascular access, improving treatment outcomes.
Area of Science:
- Vascular Surgery
- Nephrology
- Interventional Radiology
Background:
- Central arm vein obstructions significantly impair hemodialysis access.
- Venous hypertension caused by these obstructions compromises treatment efficacy.
Purpose of the Study:
- To evaluate the effectiveness of stenting for treating central arm vein obstructions.
- To assess the ability of stenting to maintain hemodialysis access on the affected side.
Main Methods:
- Fifteen stainless steel stents (8 self-expanding, 7 balloon-expandable) were implanted in 10 hemodialysis patients.
- Treatment targeted symptomatic central arm vein obstructions, including subclavian and innominate vein lesions and restenoses.
Main Results:
- Successful stent deployment resolved symptoms and corrected venous hypertension in all patients.
- Follow-up revealed a 70% cumulative primary patency rate at one and two years.
- Complications included three restenoses and one occlusion within the first six months.
Conclusions:
- Stenting subclavian and innominate venous stenoses and occlusions effectively addresses the underlying hemodynamics.
- This procedure successfully prolongs functional hemodialysis access in the majority of patients.
Background/Aims:
The aim of the study was to evaluate the efficacy of stenting for the treatment of central arm vein obstructions in hemodialysis patients in order to maintain hemodialysis from the affected side.
Methods:
Fifteen self-expanding (8) and balloon expandable (7) stainless steel stents were implanted in 10 hemodialysis patients for the treatment of symptomatic central arm vein obstructions. Thirteen lesions were treated: 6 subclavian, 4 innominate and 3 restenoses.
Results:
Stent deployment was successful in all cases leading to resolution of symptoms by correcting the underlying cause of venous hypertension. Follow-up from 3 months to 4 years revealed four deaths from unrelated causes, three restenoses at 1, 3, 4 months and one occlusion at 6 months respectively for a cumulative primary one-year and two-year patency rate of 70%.
Conclusion:
Stenting of subclavian and innominate venous stenoses and occlusions effectively corrected the underlying lesions responsible for disturbed hemodynamics and, in most cases, prolonged available hemodialysis access from the affected side.
