VAVASC trial is an observational multicentre study. The aim of this trial is to validate AVAS (arteriovenous vascular access stage) classification. The classification is used for determining which type of access is the most suitable for the patient on the basis of the patient´s vascular anatomy The methodology of this trial is to apply AVAS classification on patients who are indicated for creation of vascular access for hemodialysis. Data on these patients (vascular anatomy status, AVAS type, and predicted type of arterio venous access, demographic data etc.) will be than statistically analysed. Patients will then undergo creation of the selected arteriovenous access. They will be observed in terms of the access functionality. The follow up will be 1 to 3 years. The second aim of this study is to evaluate the relationship between AVAS classification and uninterrupted use of the created arterio venous access.

Arterio Venous Access Stage (AVAS) evaluation
Timeframe: Baseline - recruiting (Year 1) - physical examination, data collection and evaluation of Arterio Venous Access Stage (AVAS)
Arterio Venous Access type predicted
Timeframe: Baseline - recruiting (Year 1) - physical examination, data collection and evaluation of Arterio Venous Access Stage (AVAS) and predicting a type of arterio venous access
Final Arterio Venous Access
Timeframe: Follow up (up to 1-2 years) what type of arterio venous access was eventually created
Functionality of the arterio venous access
Timeframe: Year 2-3 - follow up, collection the data about the functionality (uninterrupted use) of the arterio venous access and evaluation of the relation between AVAS and the functionality of the arterio venous access
