CHIVA, this technology was first put forward by French doctor Professor Fran Ceschi. After 30 years of accumulation and summary, it has matured and proved to be a better solution to varicose veins. It is a new surgical method based on a new theoretical system, which can preserve the trunk of great saphenous vein and the normal reflux path, only minimally invasive treatment is performed on the reflux point of the cause, and the normal hemodynamic path is restored to achieve the purpose of treating varicose veins. It can be simply understood that this is a protective operation.

CHIVA has obvious advantages: (1) the trunk of great saphenous vein is preserved, which reduces trauma and can be used as a vascular graft material for other diseases in the future; (2) local anesthesia can be performed, and patients can walk below after operation without hospitalization; (3) Most of the veins are preserved, and there is almost no pain after operation, which avoids the injury of nerve and lymphatic reflux that may exist in other operations.

From 2065438 to 2005, Cochrane evidence-based medicine database summarized several RCT studies of CHIVA compared with traditional surgery. The results showed that the recurrence rate of CHIVA surgery was significantly lower than other traditional destructive surgery, and the treatment effect and experience were better.

However, CHIVA has the following disadvantages: (1) It takes at least 20 minutes to evaluate the patient's hemodynamics by ultrasound. (2) The theoretical system is complex, the training period is long, and the number of doctors who master this technology is very small, which limits its popularization. (3) Outpatients must be equipped with ultrasonic equipment, which increases the cost.

Therefore, the implementation of conventional CHIVA technology needs to have CHIVA training qualification and standardized ultrasonic hemodynamic evaluation (more than 20 minutes, the surgeon personally operates and provides the surgical strategy map); Patients can walk normally after operation without hospitalization, nerve injury and local anesthesia.

Doctors without the above experience will have worse results if they do CHIVA surgery. A study pointed out that the recurrence rate of CHIVA after 5- 10 years was significantly lower than that of traditional surgery. At the same time, if doctors who have no mature experience in CHIVA surgery implement an inappropriate CHIVA scheme, their patients will have a low cure rate and a high failure rate, even worse than traditional surgery! Among doctors who have considerable experience in CHIVA, the cure rate of CHIVA is obviously improved, which is obviously better than traditional surgery.

Of course, surgery can be done, but everyone's situation is different. Only after a detailed evaluation by a professional venous disease center doctor can we tailor a more perfect operation!
