Patients with cerebral infarction presenting with swollen feet and lower limb edema should be aware of the following reasons. The first scenario is due to reduced activity in the limbs on the paralyzed side, which results in weaker muscle contraction. Consequently, a large amount of blood accumulates in the lower limb veins, causing poor circulation and naturally leading to swollen feet. Therefore, it is crucial for patients to begin early rehabilitation training, engage in muscle massage, and perform passive joint exercises, among other activities. The second scenario that requires close attention is the formation of venous thrombosis in the lower limbs on the paralyzed side after a cerebral infarction. This condition can easily lead to venous thrombosis, which significantly contributes to foot swelling. Furthermore, it increases the risk of pulmonary embolism. It is important to complete routine coagulation tests and d-dimer examinations, as well as comprehensive lower limb venous Doppler ultrasound assessments.
