Aim: To assess the primary patency of the central veins of the upper limb after percutaneous transluminal balloonangioplasty (PTA) with bare metal stent Vs covered stent.  Patients and methods: 26 patients having venous hypertension of the upper limb on regular hemodialysis at Ain Shams University Hospitals dialysis units and Menia University were included in the study from June 2016 till June 2017. Collected data were followed up till December 2018. Patients were divided randomly into two groups, Group A: 13 Patients who underwent balloon dilatation of completely occluded or more than 50% stenosed central veins with bare metal stent and Group B: 13 Patients who underwent balloon dilatation of completely occluded or more than 50% stenosed central veins with covered stent . The primary patency, assisted primary patency and secondary patency of these procedures were assessed in a period of 18 months.  Results: The technical success rate was 100% (n=26), 1ry stenting was done in 100% (n=26) of cases. The patency rate at 18 months after intervention was 69.2% primary assisted patency and 92.3% secondary patency in bare metal stent group while it  was 100%  both primary assisted  and secondary patency at 18 months in covered stent group.  Conclusion: Percutaneous transluminal angioplasty with covered stent carries a higher patency rate in short termfollow up. But more cases should have longer follow up time in multi centers.
