Outcome and Improvement of Different Treatment in Arteriosclerosis Obliterans: a Prospective, Single-center, Observational Study

Arteriosclerosis obliterans (ASO) is a kind of lower extremity arterial disease which occurs frequently in middle-aged and elderly people. The incidence of ASO increases with age. In patients with ASO, the build-up of fatty deposits, cholesterol, and other substances (plaques) in the arteries reduces blood flow to the extremities. This can lead to symptoms such as leg pain, cramping, and fatigue, especially during physical activity. In severe cases, it may result in pain at rest, non-healing wounds, and complications such as tissue damage or infection. Chronic wound is one of the symptoms that affect the quality of life. Therefore, wound healing is also an important index for postoperative care. However, no study has reported detailed performance data for different treatments. As an auxiliary method in clinical treatment, nutrition plays an important role in improving the clinical outcome of patients in the development and postoperative stages of the disease. The effect of nutritional risk assessment and nutritional education on postoperative symptoms of ASO has not been reported. Therefore, we plan to carry out this prospective, single-center, observational study, providing new data on the efficacy, safety and cost-effectiveness for different treatment and assistive techniques in lower extremity arterial occlusive disease.
