Blockage of blood vessels in the feet may be arterial vascular blockage or venous vascular blockage. In the case of arterial vascular blockage, the lumen may be completely occluded due to arteriosclerosis-occlusive disease of the lower extremities, which usually occurs in the dorsalis pedis artery or the posterior carotid artery. The clinical manifestations of the patient are pain in the toes, decreased skin temperature, and localized numbness that worsens with activity. If the blockage is caused by a deep vein thrombosis, the patient may experience swelling of the foot, which requires anticoagulation therapy to relieve the patient’s symptoms, as well as treatment to activate blood stasis.
