A review was conducted using the following search terms: \"educational measurement\", \"vascular surgery\", and \"internship and residency\". The initial search results comprised 616 articles. After application of the eligibility criteria, just four studies were included in the review, only one of which was conducted in Brazil. Three of the studies used Objective Structured Assessment of Technical Skill (OSATS) to assess residents. However, all used separate and different supplementary checklists for evaluation of specific skills related to anastomoses. Appropriate appraisal and precise feedback during residency training are an extremely important part of residents' training. Systematic and objective feedback enables errors to be corrected and skills to be polished. Since there is no instrument for assessment of the surgical skills needed to perform anastomosis, after completion of the review a rating instrument was proposed focused on this important skill that vascular surgery residents must acquire.
