Background: Vascular anomalies (VA) include vascular malformations and tumors. The International Society for the Study of Vascular Anomalies (ISSVA) classification provides the international framework for their study and management; however, the low prevalence of these entities and the frequent misuse of terminology contribute to errors in diagnosis and management. Objective: To perform an expert consensus via nominal technique to generate diagnostic and therapeutic flowcharts for the most common VA. Material and methods: A consensus study was conducted using nominal group technique by an international panel of 17 VA experts. An extensive review of the literature and the 2025 ISSVA classification were performed, and during four meetings the proposed flowcharts were thoroughly discussed, reviewed, and validated until general agreement was achieved. Results: Six flowcharts were developed for infantile hemangioma, high-flow vascular malformations (VaM), low-flow capillary VaM, low-flow lymphatic VaM, low-flow venous VaM, and syndromic combined VaM. Each flowchart integrates clinical criteria, etiology, diagnostic approach, treatment, and follow-up, as color-coded sections. Conclusions: This study provides practical tools to facilitate accurate diagnostic and therapeutic decision-making in patients with VA, including a clinically applicable format for daily practice, providing a foundation for future validation and updates. These flowcharts as continuing medical education resources will favour the correct diagnosis and appropriate management of patients with VA.
