Objetivo: Evaluar el impacto de una consulta específica de accesos vasculares (C-FAV) con seguimiento intensivo en la permeabilidad de las fístulas húmero-axilares. Pacientes y método: Estudio retrospectivo. Entre enero de 2005 y diciembre de 2009 se realizan 108 fístulas húmero-axilares. Desde junio de 2007 se establece una C-FAV. Se realiza eco-doppler preoperatorio y seguimiento posterior al mes de la intervención y, después, cada 3 meses. Resultados: Se analizan las permeabilidades de 57 fístulas húmero-axilares realizadas desde junio de 2007 hasta diciembre de 2009 (grupo C-FAV), comparándolas con 51 realizadas durante los 30 meses previos (grupo control). No se encontraron diferencias en la permeabilidad obtenida entre ambos grupos a 12 y 24 meses, con una permeabilidad secundaria a los 12 meses de 49% en el grupo C-FAV y 52% en el grupo control. El porcentaje de pacientes reintervenidos fue inferior en el grupo C-FAV (35%) que en el grupo control (67%), p = 0,002. La media de reintervenciones realizadas por paciente fue menor en C-FAV que en grupo control (0,49 vs. 1,18, p = 0,01). Los pacientes del grupo C-FAV presentaron un menor número de reintervenciones por obstrucción frente al grupo control (0,42 vs. 1,04, p = 0,01). Conclusiones: En nuestra experiencia, el seguimiento intensivo no ha mejorado la permeabilidad de las fístulas húmero-axilares, disminuyendo no obstante las reintervenciones por obstrucción. El seguimiento de estos accesos debe ser clínico basado en datos de hemodiálisis, quedando la valoración ecográfica para aquellos casos con sospecha de malfunción (AU)
Aim: To evaluate the impact of a specific vascular access (arteriovenous fistula) unit (AVF-U) and intensive follow-up controls on the patency of humero-axillary fistulas (Hax-AVF). Patients and method: Retrospective study. Between January 2005 and December 2009, 108 Hax-AVF were implanted. From June 2007 an AVF-U was established. A preoperative Doppler ultrasonography analysis was performed and a follow-up control carried out a month after the intervention and subsequently every 3 months. Results: An analysis was made of the patency of 57 Hax-AVF performed between June 2007 and December 2009 (AVF-U Group), in comparison to 51 interventions performed during the previous 30 months (Control Group). No differences in the patency achieved were found at 12 or 24 months, with a secondary permeability at 12 months of 49% in the AVF-U Group and 52% in the Control Group. The percentage of patients needing to be reoperated was lower in the AVF-U Group (35%) than in the Control Group (67%) (P=.02). The mean number of re-operations per patient was lower in the AVF-U Group than in the Control Group (0.49 vs 1.18; P=.01). The patients of the AVF-U Group underwent fewer reoperations for obstruction as compared to the Control Group (0.42 vs 1.04; P=.01). Conclusions: In our experience, the intensive follow-up controls did not improve the patency of the Hax-AVF, although reoperations due to obstruction did diminish. The follow-up of these fistulas should be clinically based on haemodialysis data, leaving ultrasound evaluation for those cases where AVF failure is suspected (AU)

AIM: To evaluate through a specific trial on vascular access fistulas (T-VAF), the impact of intensive follow-up controls on the permeability of humero-axillary fistulas (Hax-AVF). PATIENTS AND METHOD: Retrospective study. Between January 2005 and December 2009, 108 Hax-AVF were implanted. From June 2007 a T-AVF was established. A preoperative duplex was performed and a follow-up control carried out a month after the intervention and subsequently every 3 months. RESULTS: An analysis was made of the permeability of 57 Hax-AVF carried out between June 2007 and December 2009 (T-AVF Group), in comparison to 51 interventions performed during the previous 30 months (Control Group). No differences in the permeability achieved were found at 12 and 24 months, with a secondary permeability at 12 months of 49% in the T-AVF Group and 52% in the Control Group. The percentage of patients needing to be re-operated was inferior in the T-AVF Group (35%) than in the Control Group (67%) p=0.02. The re-operation per patient average was lower in the T-AVF Group than in the Control Group (0.49 vs. 1.18 p=0.01). The patients of the TAVF Group underwent a lesser number of re-operations for obstruction as opposed to the Control Group (0.42 vs 1.04 p=0.01). CONCLUSIONS: In our experience, the intensive follow-up controls did not improve the permeability of the Hax-AVF, although re-operations due to obstruction did diminish. The follow-up of these access fistulas should be clinical based on hemodialysis data, leaving ultrasonographic evaluation for those cases where a malfunction is suspected.
