Final answer:
A leg with a venous occlusion like DVT presents with symptoms like swelling, redness, and pain. Varicose veins are enlarged, twisted veins caused by faulty valves and can be painful. Medical intervention is required to prevent complications and improve venous flow.
Step-by-step explanation:
A leg with a venous occlusion, such as deep vein thrombosis (DVT), typically appears swollen and may be painful, red, or warm to the touch. Varicose veins, which are related to venous occlusions, are enlarged veins where defective valves allow blood to accumulate and flow backward, causing the veins to distend and twist. Varicose veins are also common in the lower limbs and may appear as bulging, twisting veins that are often painful and itchy. These two conditions are indicative of issues with venous flow and require medical attention to prevent further complications.
Treatment options for varicose veins include the use of support hose, elevation of the legs, and medical procedures such as laser surgery, interventional radiologic procedures, and in severe cases, conventional surgery to remove damaged vessels. It is important to address these conditions promptly as they can lead to serious health risks like thrombus or clot formation. The major veins of the lower limb, summarized in flow charts and tables, play a critical role in venous return to the heart and when affected, can impact overall circulation.
