Clinical Staging of Lower Limb Lymphedema: Lower limb lymphedema is a relatively common disease of the lymphatic system in clinical practice. The clinical staging of lower limb lymphedema is generally divided into the acute stage and the chronic stage. Let's take a look at the clinical staging of lymphedema together.
Lower limb lymphedema can be divided according to the course of the disease:
Acute Stage: A hematoma fistula may occur locally due to injury, which can be blocked by a blood clot. Therefore, pulsating swelling often appears within a few days. Most patients have tremors and murmurs. In most cases, the arterial pulse can still be felt distally from the fistula.
Chronic Stage: This mainly refers to various manifestations caused by hemodynamic changes. Due to high-pressure arterial blood being directly infused into the veins through the fistula, venous pressure increases, leading to significant dilation of superficial veins both proximal and distal to the fistula, as well as an increase in skin temperature. In areas far from the fistula, especially at the ends of the feet, due to reduced arterial blood supply and venous congestion, nutritional changes such as thin and shiny skin, pigmentation, and ulcer formation may occur. The larger the fistula opening and the closer it is to the heart, or the wider the diameter of the artery where the fistula occurs (such as the carotid artery, subclavian artery, iliac artery, femoral artery, etc.), due to a large amount of blood flowing directly into the veins through the fistula, cardiac output significantly increases, leading to progressive enlargement of the heart and eventually causing heart failure. Local symptoms are often very typical: rough continuous vascular murmurs can be heard along both sides of the fistula, nearby veins show obvious dilation, accompanied by vascular murmurs and tremors.
