Details.
A procedure to open narrowed or blocked arteries supplying blood to the legs. Angioplasty uses an inflated balloon to stretch the artery, and a permanent metal mesh stent may be inserted to keep the artery open. Preparation includes fasting without food or water for 6 hours before the procedure. Some patients may require medication adjustments, kidney function assessment, blood testing, or intravenous fluids. Local anaesthetic is used. The procedure may help restore blood flow, improve walking without pain, or allow a leg or foot wound or ulcer to heal. Most patients experience symptom improvement within a few days, although outcomes vary.
