Deep vein thrombosis (DVT) occurs after a fracture, and once DVT occurs, it is important to prevent its complications. The most serious complication of DVT is pulmonary embolism, or partial cerebral embolism. The most serious complication of DVT is pulmonary embolism, or partial embolism of the brain. Pulmonary tethering can be directly life-threatening, so once a thrombosis occurs after a fracture, surgical intervention is needed to branch the umbilical cord to the common iliac artery to prevent DVT in the lower limbs from passing through the heart or reaching the lungs, which can lead to the corresponding complication. In addition, you need to take anticoagulant drugs to prevent the further formation of blood clots, and you can also drink more water to promote blood dilution, which can effectively prevent the formation of blood clots. After the fracture, it is still necessary to perform joint and muscle function exercises at an early stage to prevent muscle atrophy and the formation of blood clots.
