title: Ulcer healing after peripheral intervention-can we predict it before revascularization?
abstract: Complete ulcer healing is one of the most important goals of treatment for critical limb ischemia; however, it is still difficult to inform patients of the time to ulcer healing before performing revascularization. The time to ulcer healing has a great impact on the cost of treatment and patient's quality of life. To predict it, the factors that influence delayed ulcer healing should be explored. According to a review of the literature investigating ulcer healing after revascularization, the influential factors can be classified into 5 categories: (1) systemic factors; (2) clinical state of tissue defect; (3) infection; (4) wound management strategy; and (5) revascularization strategy (endovascular or open repair, the angiosome concept). It is also important to ensure sufficient blood supply to predict ulcer healing probability in the individual patient. Several new methodologies, such as measuring tissue circulation around the tissue defect and intraoperative imaging techniques, have been reported. Because the status of ischemic tissue loss and wound healing ability can affect the decision-making process in selecting the revascularization strategy, understanding the many factors that influence ulcer healing after revascularization is indispensable for physicians performing revascularization. Accumulating ulcer healing data via well-designed clinical research can help to establish a new paradigm for the revascularization strategy from the viewpoint of ulcer healing.
