Consecutive patients fulfilling the inclusion criteria will be asked to the study by vascular surgeon or interventional radiologist after the diagnostic imaging study. A consensus of a vascular surgeon and interventional radiologist is required: for an elective patient this is acquired in a weekly vascular meeting and for an urgent patient by consultation. The patient will be provided no additional compensation for participation but normal travel expenses for clinical visits will be paid. The patient`s identity and personal study data will be available only for the researchers of the trial. Normal clinical patient insurance is applied.
