Introducción: La vena basílica se caracteriza por ser un vaso profundo que en la mayoría de los casos requiere superficialización y trasposición quirúrgica.
Material y métodos: Estudio retrospectivo de 119 FAVn HB S-T en pacientes con insuficiencia renal crónica 5D implantadas en un solo acto quirúrgico (2011-2015). Se analiza el porcentaje de permeabilidades primaria (PP), primaria asistida (PPA) y secundaria (PS), así como las complicaciones asociadas. Análisis de permeabilidades mediante curvas de supervivencia Kaplan-Meier y análisis univariante mediante Log Rank (Mantel-Cox). Se considera significativa una p ≤ 0,05.
Resultados: Edad media 67,9 an˜ os y 63,8% hombres. Durante el período de seguimiento se objetivaron un total de 57 complicaciones: 24 estenosis (42,1%), 11 trombosis (19,2%), 7 síndromes de robo vascular (12,2%), 7 edemas de extremidad superior (12,2%), 6 hematomas pospunción (10,5%) y 2 infecciones (3,5%). Los porcentajes de PP obtenidos a 1, 6, 12 y 24 meses: 92,4, 79,8, 66,3 y 52; PPA: 94,1, 87,3, 80,4 y 65,6%, y PS: 95, 89,1, 84 y 67,5%. Se constataron diferencias significativas en las curvas de PP, PPA y PS según la etiología, presentando peores permeabilidades los diabéticos respecto a la vascular e idiopática (p = 0,037, 0,009 y 0,019).
Conclusiones: La implantación quirúrgica de FAVn HB S-T en un solo acto ofrece buenas tasas de permeabilidad y escaso número de complicaciones asociadas. La diabetes mellitus representa un factor de peor pronóstico quirúrgico. Entre las mayores ventajas destacan una mejor optimización de los recursos sanitarios y menor tiempo de permanencia del catéter venoso central.
Background: The basilic vein is a deep vein which usually requires superficialisation and surgical transposition.
Material and methods: This is a retrospective study of 119 BBAVF-ST in patients with stage 5D chronic kidney disease who received an implant with a one-stage surgical technique (2011-2015). The percentage of primary (PP), assisted primary (APP) and secondary (SP) permeabilities were assessed, as well as the related complications. We analysed the permeabilities using Kaplan-Meier survival curves and a univariate Log Rank analysis (Mantel-Cox).
P values less than or equal to 0.05 were considered as significant.
Results: The mean age of the study group was 67.9 years, with 63.8% of the subjects being male. A total of 57 complications were detected during the follow-up period: 24 stenosis (42.1%), 11 thrombosis (19.2%), 7 vascular access steal syndromes (12.2%), 7 upper limb oedemas (12.2%), 6 post-puncture haematomas (10.5%) and 2 infections (3.5%). The percentages of PP obtained at 1, 6, 12 and 24 months were 92.4%, 79.8%, 66.3% and 52%; APP: 94.1%, 87.3%, 80.4% and 65.6%, and SP: 95%, 89.1%, 84% and 67.5%, respectively. Diabetic patients presented with significantly worse permeabilities than vascular or idiopathic patients: (P = .037, .009 and .019, respectively).
Conclusions: According to the results obtained in our study, the one-stage surgical implementation of BBAVF-ST presents high permeability rates and a small number of related complications. Diabetes mellitus is a factor related to a worse surgical prognosis. Some of the biggest advantages are the greater optimisation of health resources and a shorter time in which the central venous catheter needs to remain in the body.
