Leg swelling in the elderly may be arterial disease, commonly seen in thrombo-occlusive vasculitis, where the arterial system is of poor quality due to the presence of advanced age, hypertension and hyperlipidemia in the patient, thus causing arterial stenosis and poor blood supply to the lower extremities, causing edema in the tissue cells of the legs, resulting in leg swelling. It could also be saphenous varicose vein, due to prolonged standing and engaging in physical activities, the saphenous vein becomes poorer in quality and tends to dilate, with venous reflux obstruction, causing leg swelling. It may also be venous thrombosis, which often results in venous thrombosis due to huge surgeries, after thoracic and abdominal trauma, and is manifested by swelling of the limbs and local leg swelling, along with an increase in leg temperature. Leg swelling is also often seen when patients have left heart insufficiency.
