Signs of hyaluronic acid embolization

With the development of society and the progress of human civilization, people's pursuit of beauty is getting higher and higher. Plastic surgery has become a problem that people are more concerned about. Various beauty salons have also begun to emerge, and their beauty projects are also diverse. Among them, hyaluronic acid injection has become a common cosmetic method. Generally, there are no side effects, but the possibility of accidents cannot be ruled out, which may lead to embolism after hyaluronic acid injection.

Vascular embolism can be divided into two types: arterial and venous. Arterial embolism tends to occur quickly and has obvious symptoms, such as pale skin and severe pain in the supplied area; venous embolism occurs slowly, with gradual darkening of the skin color and obvious dull pain within 24 hours after injection. Once arterial embolism occurs, the hyaluronic acid particles that enter the blood vessels can cause antegrade embolism, leading to skin necrosis in the blood supply area, which often occurs at the tip of the nose and nasolabial groove. The most serious complication is that the hyaluronic acid that enters the blood vessels flows retrogradely due to excessive injection pressure, causing blindness.

1. Direct embolization. During the injection, the needle directly penetrates into the thicker blood vessels, and the hyaluronic acid is directly injected into the blood vessels, causing physical embolism. Because the blood vessels on the face are mostly thin, it is not common in reality.

2. Indirect embolism. During the injection process, the needle tip causes trauma to the blood vessels when it penetrates or is withdrawn, causing blood to flow out slowly. The operator continues to inject hyaluronic acid into the tissue gap outside the blood vessels without noticing. The bleeding and the injection of hyaluronic acid increase the pressure between the tissues. When the external pressure reaches a balance with the systolic pressure of the blood vessels, but exceeds the diastolic pressure of the blood vessels, the blood will flow back, and the mixture of blood and hyaluronic acid in the tissue gap will be pressed back into the blood vessels, forming an embolism.

Injectable beauty requires aesthetics, medical science, and medical technology to support it. The patient should have an objective and calm attitude: there are too many informal medical studios on the market that use pricing tactics, but you get what you pay for. Whether the product is regular and the doctor's skills are up to standard requires knowledge of sterility, anatomy, and medical technology. The person performing the operation must be a doctor with the necessary medical ethics, must use regular products, and must be strict, conscientious, meticulous and responsible in order to control the risks to the greatest extent possible.
