Brachial Vein Transposition Versus Arteriovenous Graft – Two-year Results

Detalhes bibliográficos
Resumo:	Background: Proper vascular access is essential for effective hemodialysis. There are three main access modalities: arte- riovenous fistula (AVF), arteriovenous graft (AVG), and central venous catheter. AVF has better patency and fewer complications, with lower morbidity and mortality rates. Some patients have limited superficial venous patrimony, and the best vascular access remains undetermined, with AVG and brachial vein transposition (BVT) representing upper limb alternatives. Our aim is to inves- tigate BVT and AVG followed by our institution regarding patency and need for intervention. Methods: This paper is based on a retrospective analysis of BVT and AVG followed/intervened our center between 2014 and 2018. To primary outcome was to define and compare patency rates for each group. Primary failure and need for reinterven- tion were considered secondary outcomes. Results: There was no statistically significant difference between primary and secondary patency in both groups. BVT has a higher post-intervention primary patency and fewer interventions due to thrombosis, despite the overall number of inter- ventions per patient similar to AVG. Conclusions: Despite the absence of a statistically significant difference in secondary patency and the need for reinter- vention between BVT and AVG, thrombosis-free time is higher in the BVT group. Overall, BVT is a valid access option that should be considered in patients with no other autogenous access alternative in upper limbs.
