Clinically, veins are categorized into superficial and deep veins. When different veins are blocked, the patient’s symptoms are different, and the common manifestations include limb swelling, blood vessel streak-like changes, and so on. For superficial vein occlusion, it is usually caused by superficial vein thrombosis, and patients often show redness and swelling of limbs, increased skin temperature, superficial varicose veins, skin atrophy, etc. For some deep vein occlusion, patients may show swelling of limbs, varicose veins, and skin atrophy. As for some of the deep vein blood vessel blockage, patients may have localized swelling and vascular streak-like changes. Often the blockage will affect the quality of life and health of the patient, so the person with the blockage needs to cooperate with the doctor for treatment. Symptoms of venous occlusion may vary depending on the location of the occluded vein. It is recommended that people with venous blood vessel blockage should cooperate with their doctors and have regular medical checkups.
