The CHIVA procedure is a hemodynamic-based outpatient varicose vein procedure that has the disadvantages of being time-consuming, costly, varying skill levels, and expensive. 1. Time-consuming: It requires doctors to master standardized ultrasound hemodynamic assessment techniques, and the assessment takes at least 20 minutes or more. 2. Large difference in skill level: The theoretical system of CHIVA procedure is more complicated, its training cycle is relatively long, and the skill level varies greatly for doctors. 3. High cost: Although CHIVA surgery is an outpatient surgery, it requires outpatient clinics to be equipped with ultrasound equipment, which leads to high cost, and it is not possible to reimburse the surgery cost with medical insurance, which has certain requirements on the patients’ affordability. 4. Easy recurrence: The biggest disadvantage of this surgery is that the diseased venous vessels are found through the examination of blood flow, and for the saphenous vein trunk, there is a possibility of retention, and there is a possibility that new capillaries may be formed on the basis of this, which will make the varicose veins appear to recur. It is recommended to consider the surgical situation and choose the appropriate procedure under the guidance of a specialized physician.
