A lot of candidates have been taking photos of their faces after autologous liposuction, and they feel like a different person. The premise is: this is a successful surgery. Although the autologous fat comes from the candidate’s own body, the filler has no risk, it does not mean that the filler surgery is absolutely safe. 1, the risk of injecting fat into blood vessels This risk is the biggest risk of fat filling. The consequences of fat into the blood vessels, generally, the blood vessel blood supply area of the sensory-motor function of the loss of skin and subcutaneous tissue lack of nutrients and oxygen, continued for a period of time after the occurrence of tissue degeneration and necrosis and ulceration. In more serious cases, fat injection into large blood vessels may cause death. Blunt needles are safer than blunt needles, but if they are overly fetishized and you lose your vigilance, it can be a bad thing. The consequences of fat injection into blood vessels is very serious, whether blunt needle or sharp needle have the possibility of fat injection into blood vessels, the focus is familiar with the anatomy, standardized operation, skilled technology. 2, the risk of postoperative unevenness or asymmetry on both sides This symptom, not necessarily a problem of the doctor’s operation, for example: uneven filling during the operation, uneven absorption after the operation, postoperative pressure touching of the filling site and so on, this situation may occur. Postoperative fixation with adhesive tape can prevent unevenness and have a certain leveling effect, while also having a certain reduction in the survival effect. 3, the risk of postoperative fat liquefaction Fat liquefaction is related to infection, postoperative should pay attention to the application of antimicrobial agents, effective prevention of infection occurs. The consequence of fat liquefaction may form radicalization and hard knot formation. Facial fat filling is relatively rare, but it is prone to occur in fat breast augmentation, usually after 0.5~2 years after surgery, which only affects the hand feeling and has little effect on the shape. There is basically no way to deal with it, and it may gradually soften through several years. 4.Risk of low fat survival after surgery The survival rate of fat is related to various factors, such as: the quality of fat, the instrument used to take fat, pressure, anesthetic concentration, the process of fat treatment, the instrument used for injection and so on. 5, the risk of high fat survival after surgery We are all worried about the low fat survival rate, why is high fat survival also a risk? It depends on which way you use to improve the survival rate. For example: increasing the number of fills. If you increase the number of wrong filling too much, the fat cells are too much survival, there may be “longevity male forehead”. 6, the risk of postoperative bruising Fat filling process if the injury to blood vessels, or the patient recently ate anticoagulant drugs, or the patient coagulation function problems, can cause bruising. Bruising is generally temporary, mostly within 2 to 4 weeks to subside, individual candidates may need more than 3 months. 7, the risk of serious postoperative swelling After liposuction, the degree of swelling varies, the majority of people swelling degree is relatively light, but individual candidates swelling may be more serious. For cases with severe swelling, you can give antihemorrhagic and anti-swelling medication after surgery, and ice packs within 3 days will help reduce swelling.
