Introduction
Lower limb vascular occlusion mainly refers to lower extremity arteriosclerotic occlusive disease, a common vascular condition. It is typically accompanied by symptoms such as swelling, pain, changes in skin color, decreased skin temperature, and weakened pulse. Patients experiencing these symptoms should seek medical attention promptly. Treatment may include medications such as enteric-coated aspirin tablets, isosorbide mononitrate tablets, and Compound Danshen Dripping Pills, taken as prescribed by a physician.
Lower limb vascular blockage typically presents symptoms such as swelling, pain, changes in skin color, decreased skin temperature, and weakened pulse. If any discomfort occurs, it is recommended to seek medical attention promptly. The details are as follows:
1. Swelling: When lower limb blood vessels are blocked, noticeable swelling may occur in the affected leg or foot. This happens because a blood clot obstructs venous return to the heart, causing fluid to accumulate in the tissues and resulting in edema.
2. Pain: Patients may experience pain in the lower limbs, especially during walking or standing. The pain may be localized in the calf or thigh and may be accompanied by tenderness upon touch. This results from impaired blood circulation due to the clot, leading to local ischemia and inflammatory response.
3. Changes in skin color: Lower limb vascular blockage may cause the skin to appear darker or cyanotic, particularly in the toes or feet. This discoloration occurs due to inadequate blood supply and tissue hypoxia.
4. Decreased skin temperature: The affected lower limb may feel colder than usual, with noticeably reduced skin temperature. During conditions such as peripheral arterial disease, blood flow is compromised, impairing heat delivery to the extremities and causing a drop in local temperature.
5. Weakened pulse: Patients may notice a diminished or absent pulse in the dorsalis pedis or posterior tibial arteries. This occurs because severe arterial blockage restricts blood flow, making the normal pulse difficult to detect.
If the above symptoms occur, patients may follow medical advice to use medications such as enteric-coated aspirin tablets, isosorbide mononitrate tablets, or Compound Danshen Dripping Pills for treatment. Additionally, patients should maintain appropriate physical activity, avoid prolonged sitting or standing, wear comfortable shoes and socks, and regularly monitor lower limb circulation to prevent complications.
