Background: Vascularity is an important parameter closely associated with the scar maturation. Reliable and accurate measurement of vascularity helps to monitor the scar change and adopt targeted interventions to prevent excessive scarring and achieve promising outcomes. However, there is no consensus on the assessment tools for the vascularity measurement in scars. This systematic review presents evidence on the available vascularity measurement tools. Methods: A systematic literature search was done using PubMed, CINAHL, Embase and Science Direct databases. Studies, which used non-invasive measurement tools and explored their clinimetric properties, were identified and included in this review. Results: A total of 1458 articles were obtained, and 26 articles were finally included in this review. Subjective vascularity measurement scales include the Patient and Observer Scar Assessment Scale (POSAS), the Vancouver Scar Scale (VSS) and the modified Vancouver Scar Scale (mVSS) while objective vascularity measurement devices consist of the color-measuring device, the blood flow measuring device and the morphological imaging device. Conclusion: Subjective scales are easy to use and have acceptable reliability to give a preliminary impression of the scar vascularity. Three types of objective devices are not equivalent and are mainly based on the blood flow and angiogenesis to quantify the scar vascularity.
