<unk>  surgery is mainly used to treat cases of femoral artery blockage that cause more severe symptoms that restrict completion of daily tasks such as peripheral artery disease and claudication, or cases that have not responded well to other treatment options . Before surgery is considered, adjustments are made to lifestyle habits such as quitting smoking or exercising more, or using medications, to relieve or improve symptoms. Claudication refers to pain in the lower limbs that may be felt while exercising, walking, or simply while resting. A blocked femoral artery reduces the blood flow to the areas of the thigh and calf, causing the pain that leads to claudication. Severe pain caused by claudication can lead to a person having very restricted ability to move, and pain while resting is often a sign that the condition has worsened. Claudication is also considered a symptom of peripheral artery disease. Popliteal<unk>  surgery may be performed on people with the following symptoms and conditions: * Disruption in daily life or the ability to walk from intermittent claudication * Persistent wounds in the leg * Infection or gangrene * Ischemic rest pain (due to lack of blood circulation resulting in leg pain at rest) Efficiency Generally, a vein<unk>  lasts at least 5 years in 60-70 percent of people. However about one-quarter to one-third of people will need additional procedures and follow-ups to maintain the condition of the graft. To minimise postoperative complications and a second<unk> , correct postoperative care and surgical techniques must be used. In comparison, synthetic grafts are more likely to become occluded in the future than using the person's blood vessel. A synthetic graft remains open in 33 to 50 out of 100 people 5 years after Popliteal<unk>  surgery was carried out, whereas using veins, the<unk>  remains unobstructed in 66 out of 100 people. Moreover, the particular vein, great saphenous vein was shown to be more durable over the years after surgery. Also, when comparing the efficacy of using PTFE or the great saphenous vein in people with claudication and critical limb ischemia, the latter showed better long term results. A second<unk>  may be required if a blockage forms in the<unk>  graft later on. Over time, there is a decreasing trend of percentage patency (likelihood a vessel will remain open) in popliteal<unk>  surgery, 88% in the first year, 79% and 76% at 3 and 5 years respectively. Environmental conditions and overall patient health may also affect the patency of the graft.
