The clinical manifestations of deep vein thrombosis of the lower extremity are mainly sudden swelling of one side of the limb, localized pressure and pain, superficial varicose veins, femoral bruising and femoral whitening. The details are as follows:
1. Sudden swelling of one side of the limb is the most common clinical manifestation, with localized pain, which is aggravated when walking.
2. The site of DVT is often painful with pressure and pain deep in the calf muscle when the foot is bent sharply to the dorsal side.
3. DVT can cause superficial varicose veins.
4. femoral bruise: when the thrombus extensively involves the intramuscular venous plexus of the lower limb, the iliofemoral vein and its side branches are all blocked by the thrombus, and the tissue tension increases, resulting in spasm of the artery of the lower limb, and the limb ischemia or even necrosis. Clinical manifestations of severe pain, the affected limb skin shiny, accompanied by blisters or blood blisters, the color of the skin is blue-purple.
5. femoral leukoedema: when the deep veins of the lower limbs are acutely embolized, when combined with infection, stimulate the arteries to continue to spasm, see the swelling of the whole limb, skin pallor and subcutaneous network of small vein dilatation.
