As an alternative method to predict flow and maturation, the use of thermal cameras has been proposed, due to their ease of use, reproducibility and low cost.

Flow in the proximal humeral artery increased by 621.6 ml/min (±548.5; p < 0.001). There was a trend towards higher flow velocity in the AVF at lower postoperative hand temperature.

A linear regression was also performed with the variables analysed to identify independent prognostic factors that could be predictors of AVF flow, with temperature changes being excluded as a predictor.</p><p id="par0030" class="elsevierStylePara elsevierViewall">By way of discussion, we know that creating an AVF preferentially distributes arterial flow to the low resistance venous territory rather than the distal arterial system of the limb, due to the increased distal peripheral resistance, and this could result in a decrease in temperature of the ipsilateral hand due to hypoperfusion. Our results, both in the comparison of pre- and post-surgery temperatures and in the relative temperature change in the hand on the operated arm, showed that these changes occur immediately after creation. However, we did not find a relationship between this decrease in temperature and the increase in postoperative fistula flow which would enable us to associate them and recommend their use as a predictor of AVF flow or its subsequent maturation.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In a previous study,<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> a thermal camera was also used to measure temperature distal to the AVF (as a binary factor for cooling or non-cooling of the limb), and significantly predicted correct maturation and patency of the AVF with a sensitivity of 96% and 96% and a specificity of 68% and 69% respectively. However, they did not compare temperature change with postoperative flow. Our results, even when redoing a secondary analysis by binary groups (cooling or not) do not support this relationship (p = 0.331), so we believe if it is not significantly related to intraoperative fistula flow, it is unlikely to be useful as a predictor of maturation.</p><p id="par0040" class="elsevierStylePara elsevierViewall">In conclusion, we found that there was a decrease in distal temperature following the creation of the fistula in the hand on the operated arm. However, according to our results, this change was not significantly related to AVF flow and temperature changes are therefore unreliable as a predictor of maturation.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2022-08-08" "multimedia" => array:2 [ 0 => array:8 [ "identificador" => "fig0005" "etiqueta" => "Fig. 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 751 "Ancho" => 755 "Tamanyo" => 77600 ] ] "detalles" => array:1 [ 0 => array:3 [ "identificador" => "at0005" "detalle" => "Fig. " "rol" => "short" ] ] "descripcion" => array:1 [ "en" => "<p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Thermal image after the creation of an AVF, comparing the hand on the intervened arm (on the left of the image) with the hand on the non-intervened arm (on the right of the image).</p>" ] ] 1 => array:8 [ "identificador" => "tbl0005" "etiqueta" => "Table 1" "tipo" => "MULTIMEDIATABLA" "mostrarFloat" => true "mostrarDisplay" => false "detalles" => array:1 [ 0 => array:3 [ "identificador" => "at0010" "detalle" => "Table " "rol" => "short" ] ] "tabla" => array:2 [ "leyenda" => "<p id="spar0015" class="elsevierStyleSimplePara elsevierViewall">AFV, arteriovenous fistula;
