Introduction
Central venous obstruction and stenosis are common complications that lead to access dysfunction and morbidity in patients on dialysis.
Patients and methods
This is a prospective study that was conducted at a tertiary referral center, and 30 patients on regular dialysis who presented with venous hypertension in the upper limb were enrolled. Proper history and examination was done. All patients underwent angioplasty of the lesions, and follow-up was planned at 1, 3, 6, and 12 months. Assessment of primary and assisted primary patency rates were used as the main outcome of this study with assessment of short-term results of percutaneous transluminal angioplasty (PTA) of failed and failing arteriovenous fistula in hemodialysis patients.
Results
The study was conducted on 30 patients with end-stage renal disease, comprising 21 males and nine females. The mean age was 53.8±14.5 years. Technical success was achieved in 24 (80%) patients. The rest of the patients showed an improvement of their lesions but with a residual stenosis of 30–60%.
Conclusion
Endovascular management of central venous stenosis and occlusion is an effective and safe procedure in patients on regular hemodialysis with acceptable primary and assisted primary patency rates.
