- Secondary Outcome Measures
Name Time Method <p>To compare preoperative factors between groups: - Demographic characteristics:<br /><br>age, gender, length, weight, BMI, smoking, use of drugs or alcohol, dominant<br /><br>arm, race. - Co-morbidity: indication AVF, Diabetes Mellitus, hypertension,<br /><br>hypercholesterolemy, peripheral arterial disease, etc. - Use of medication -<br /><br>Laboratory results. To compare operative factors between groups: - Duration of<br /><br>operation, duration of bloodless surgery, complications. To compare<br /><br>postoperative outcomes between groups: - Complications: death, hematoma,<br /><br>stenosis, occlusion, decrease of flow, bleeding, infection, pseudoaneurysm,<br /><br>accessory veins, steal syndrome, non-maturation, cardiac en pulmonary<br /><br>complications, reintervention. - Primary patency - Secondary patency</p><br>
