Some wounds do not heal because of lack of blood supply to the wound. Vascular studies are performed to analyze bidirectional vascular flow, vein availability and quality, vein mapping with various methods such as duplex scan, duplex ultrasound, etc.
These studies are important because if there is not enough blood reaching the wound. the wound may never heal so revascularization by a surgeon is required to reestablish the blood circulation in the area of the wound and can save the limb.
