MATOS, Norton de et al. Basilic Vein Transposition: improvement of the surgical technique. Angiol Cir Vasc [online]. 2012, vol.8, n.3, pp.139-145. ISSN 1646-706X.

Introduction: The expanding haemodialysis population has lead to increased requirement for more complex vascular accesses. Modifications introduced in basilic vein transposition technique are intended to streamline the procedure and reduce its morbidity. Methods: All patients who underwent BVT from September 2005 to September 2009 in CHP-HSA were prospectively reviewed. Results: Seventy-four BVT were performed in 74 patients. Patients had a mean of 2.0 previous access attempts. BVT was the first access in 20.3% of the patients. Median follow-up was 14.5 months. There were two primary failures. Secondary patency rates were 95.7%, 85.1% and 62.2% at 3, 12 and 24 months, respectively. Diabetes was associated with poor patency. Perioperative complication rate was 28.4%, with infection being the most frequent (n=6, 8.1% of all TVB). Thrombosis was the main cause of failure, occurring in 24.3% of all TVB. Conclusion: Autologous access superiority is well established. BVT is an underused technique due to its surgical expertise needs and logistic demands. We improved the surgical technique and the tunneling technique, reducing the size of the incisions and the time of operation. Our results showed a good secondary patency rate and, in the authors view, this technique should be more widely used.
